I’m back into Ham Radio after many years of being out and I love it even more now!

I live in Raleigh, NC where I’m self-employed with wife Barbara KI4GUM. As an only child, it fell to me to care for my parents, who lived in DC. A few years ago they peacefully passed in their home, and about that time I remembered how much I enjoyed Ham Radio. As I was driving to a family reunion near Allentown, PA with my friend who helps me drive each year, Paul Apollonia, N3GCA, who is a Ham from Philadelphia, the subject naturally came up.

We stopped in HRO to buy an ICOM ID-51A because I wanted a radio that could do digital and they said that D-Star was more active on the east coast. Then I found out that we don’t have a D-Star repeater working in this area yet (fingers crossed). Check out my video “Getting Back Into Ham Radio” http://bit.ly/backintohamradio.

When I returned to the hobby I realized I wanted to do my part to help grow Ham Radio participation in productive ways. My business keeps me extremely busy so whenever I leave the house I need to make money. I decided the best way for me to fulfill this commitment is by applying my Success Coaching and marketing skills.

I am enjoying myself immensely helping people pass their various Ham exams, expanding awareness of the hobby and encouraging constructive use of Ham Radio. Yes, in our current world, people are on their cell phones a lot and yes, there are probably a thousand ways Ham Radio is not what it “used to be,” but continuing to lament these facts won’t make any difference.

For myself, a more effective approach is to ask: “what can we each do today to promote this hobby that we love so much?” In order for Ham Radio to continue flourishing, we must make peace with the existence of social media and smartphones. Almost 3 and a half billion people now use social media, the majority of them on their smartphones, which is about 3/7th of the entire planet. Instead of complaining, I say let’s put social media to work for us by using it to collect new members and to share the value of Ham Radio.

Here are the actions I’ve taken thus far:
– My Ham Radio Youtube channel, with 200 subscribers: http://bit.ly/backintohamradio
– My Facebook page, started on Dec 8, 2019, with over 1800 likes: https://www.facebook.com/ki4cfs
– My Learning Ham Radio FB group with over 160 members (started in December) https://www.facebook.com/groups/LearningHamRadio/ and
– My website for relevant resources and content http://KI4CFS.com

You may wonder if I’m getting paid somehow for these actions, or what’s in it for me. I have multiple answers: for one, I get a personal high from the idea that I might be able to make a difference in Ham Radio on a global level. I have invested about $300 of my own money to get started, now I need to invest only my time and attention.

If I’m ever selling a product, it would be just for personal fun–I will only put it on my website – KI4CFS.com (I would never mention it on the air or put it on my other Ham Radio sites). If I am given any products to review, I will fully disclose the relationship I have with that product’s seller. I aim to keep my participation with Ham Radio pure.

My mission is the constructive global growth of Ham Radio today! If you have a similar mission I’d like you to join me.

If we don’t use it we will lose it! I know that there are a lot of great aspects to Ham Radio today that could enhance the lives of people of all ages no matter where they live. I believe that if something good happens in Ham Radio and you don’t share it online then you are acting as if nothing good happened. I also believe that if you listen without at least sharing your call sign then you are robbing us all of your company and if you don’t talk, your wisdom, plus you are robbing yourself of the benefits of connecting with others.

It is our responsibility to let the world know what is fun, useful and beneficial about Ham Radio; it is not the world’s responsibility to discover it on its own. If you don’t hear anyone on the airways that is because YOU are not speaking. Please at least try to put out a long and clear call mentioning the frequency.

Want to help me directly? Offer to let me interview you on some educational topics for the Youtube channel. Visit my web pages and like, share or comment there. Share any relevant content you think has value.

For those of you who find yourselves talking about how it used to be, cut it out! Instead, ask yourself what you can do today to support this great hobby. Keep taking action in a positive direction. One more update, I just passed my Extra exam. That was hard.

Me with a few of my Ham Radios

How do you add a repeater to memory on the BTECH UV-5X3?

Steps for programing in a Repeater on the Baofengtech BTECH UV-5X3 Ham Radio Tri-band Transceiver

Contributors: Martin Brossman, KI4CFS (http://KI4CFS.com/ ) and Jim Unroe KC9HI (http://www.miklor.com/) . 

Note: This radio will let you set an “offset” in “Frequency Mode” or VFO mode but it does not let you save in memory. To save a repeater in the memory you need to first save the receive frequency, the frequency that the repeater transmits on. Then we save the frequency that the repeater receives on (including a Tone if required). For example, if your local repeater is 146.640 with no tone. The offset for that repeater is -600 (600KHz or .6MHz). Then the second number you will save in memory is 146.040 (146.640 – .600). 

BTECH UV-5X3

If you want to put in a simplex frequency, like 146.520 then you would save it once for “Receiving” Memory. 

Steps for saving a repeater in the BTECH UV-5VX3

Let’s say you want to access a 220 repeater. One in my area is 224.160 with an offset of -1.6 Mhz and a tone of 91.5 Hz. 

1st you need to calculate the Transmit frequency and that would be 224.160 – 1.6 = 222.560. This means I want my BTECH UV-5X3 to transmit on 222.560 (sending out a “sub-audible” tone of 91.5) and receive on 224.160. 

You can only add a channel to a memory location that is empty. 

We need to be in “Frequency Mode” or VFO by pressing the orange button (it toggles between “Frequency Mode” and “Channel Mode” or MR) 

You need to have the little up triangle on the top line.  Press the blue button “A/B” and notice how the little upward-pointing triangle to the left of the number point. It needs to be on the top line before you put in the frequency. 

Next use the keypad to enter the frequency of the “Repeater”, the receiving frequency or the transmitting frequency of the Repeater (all the same thing, just different views and ways to say it). 

Note: When you press “MENU” if you wait too long before you do something it will pop back to whatever was on the screen before you press “MENU” (timing out). Just press “MENU” and continue. 

Press “MENU” and type in 27 or use the up and down arrow till you see “MEN-CH”. Then press again “MENU” to jump to the lower line with the memory channel (the menu’s edit mode). If you see CH and a number something is saved in that memory channel. You can use the up and down arrows on the keypad to find an empty memory channel.  

Once you see the memory channel you want to save the repeater in then press “MENU” again and you should hear “Receiving” Memory. Now the frequency to “listen” is saved. 

Next press “EXIT” for exit and in the “Frequency Mode” or VFO mode enter the transmit frequency (In our example that would be 222.560). Note: If you are math-challenged you can set MENU 25 (SFT-D) to “-” and MENU 26 (OFFSET) to 001.600 and tap the [*] key to put the radio into “reverse” mode to display the TX frequency (an “R” will appear in the upper-status display area).

If the Repeater requires a tone follow the next step and if not skip it.

Next, you will enter the “tone” to transmit along with the transmit frequency by selecting “MENU” and go to “MENU” 13 (T-CTCS) by entering 13 on the keypad or using the up and down arrows to get to 13. Click “MENU” a second time and it will jump down to the line to select the transmit sub-audible tone. If you have not added this before you will see the word “OFF”. Press the up or down arrows on the keypad till you see the tone required by the repeater or jump directly to it by keying it in. In our example that would be 91.5. Then click “MENU” again to set the tone and “EXIT”.

You will be saving the transmit frequency in the same memory location next. Press “MENU” enter the number 27 and press “MENU” again. Make sure it is still on the same memory location and press “MENU” again. You should hear “Transmitting  Memory” and it is set. Press “EXIT” to exit. If you used “reverse” mode to set the TX frequency, don’t forget to tap the [*] key to exit “reverse” mode (the “R” will go away).

Toggle the orange “VFO/MR” button to “Channel Mode” or MR. Use the up and down arrows or key in the 3-digit channel number to get to the memory location you just saved the repeater on and click to talk. Of course call out your call sign when you test it. If you are in range the repeater should open and you will hear a response.  See this video of a similar radeo https://youtu.be/CrG0El1KkIM 

A video walking through the basic steps above?

Q&A

How do I save a frequency that I just want to monitor and not transmit to?

If you want to just listen to a frequency and not broadcast on it, here is a trick that will minimize the risk of broadcasting on a channel by mistake that would cause a big program. 

you wanted to manually program a channel to monitor a frequency and make sure you were not able to transmit on that frequency, this would be your only option.

For this exercise, we are wanting to monitor 162.450 MHz (one of the NOAA weather radio frequencies in the USA). We have already switched the radio to VFO mode, selected the top display line, erased memory 004, set STEP to 2.5 K and set TXP to LOW.

key in 162450 [NOAA WX Radio frequency] store to memory 004 using menu 27 key in 462713 (will automatically round down to 462.7125) [GMRS ch 7] store to memory 004 using menu 27

Now you can monitor the NOAA WX Radio on channel 4 and if you accidentally press the PTT button, the transmission would be on GMRS channel 7. Not strictly legal, but a much better option than transmitting on 162.450 MHz. If you are a ham, you can set TX to any frequency in the 2 meters, 70 centimeters or 1.25 meter (if available) bands where FM transmissions are permitted and won’t cause interference.

How do I save in memory a simple simplex frequency like 146.540?

There is no need to save twice. Please try this to see for yourself. Program a memory. As soon as you complete the step where the radio says “receiving memory”, stop. Switch to MR (channel) mode, select the channel that was programmed and press the PTT button. It will transmit because it is already a simplex channel. The second write for a repeater (or odd-split or cross-band) channel is just converting a simplex channel to a duplex channel. 

How do I delete something from memory? 

Press “MENU” once, then enter the number 28 on the keypad or use the up and down arrows till you get to 28 and see “DEL-CH”. Next press “MENU” a second time and notice the little up arrow (or triangle) on the goes down a line and become a down-facing arrow (or triangle). You will hear “Delete Channel”.  Use the up or down arrows to select the memory location you want to delete. Memory locations that have something stored in them look like this: “CH-127” and memory channels that don’t have anything stored in them look like this: ” 127”. When you find the memory channel you want to delete press “MENU” again and you will hear the word “Confirmed”. You can then exit “MENU” by pressing EXIT”. If you do not move fast enough it will leave the “MENU” mode and you will have to press “MENU” again. If you want to leave without deleting press “EXIT”

How do I adjust the squelch?

Select “MENU”, then press 0 and you will see “SQL” with a number under it. Press “MENU” a second time and the little triangle or up-arrow on the top line will jump to the bottom line and you can use the up and down arrows on the keypad to change the number or just enter the number. In most cases, a level of 1 or 2 will work. Last press “MENU” again and you will hear it say “Confirm” . You can then click “EXIT” to leave the menu.

A story of an Amateur Radio Emergency Communication Van

20/02/01 at 4.06pm   /   by Martin Brossman   /   0 Comment

Ham Radio History – A story of an Amateur Radio Emergency Communication Van that Ernie Martin – WØAUU, was involved, in his own words. Posted by Martin Brossman KI4CFS

The Amateur Radio Emergency Communication Van

That old 1970 Chevy step van was a pile of junk and needed everything.  We rebuilt the engine and had the transmission rebuilt. The steel studs on the inside most had rusted off at the bottom we had news ones made at a local trailer factory.  Then added wood 2X2 studs so insulation could be added. We had new lower side panels made and put on and added a window and had it painted. We insulated the floor and put in electric heat.  Then added a light bar to the top that had red, green and yellow lights. We did have a state red light permit but never used them. That old van was too big to run with red lights so I removed that fuse just to be sure.  We did use the combination of yellow and green lights a few times. There were two banks of 12-volt batteries, each bank would run all the radio gear for two hours. They could be charged from the engine or from a gas generator and we also had 13 volts of solar power that would charge the batteries.

The lights
The Van!

There were four operating stations, one for 80 meters, one for 20 meters, one for 2 meters and the mobile repeater and one for FRS and ATV.  We had a radio for aircraft communications, one for tugs on the Mississippi it even had a satellite phone that the Red Cross used several times. Yes, it even had a CB radio. It had a flip-up 2-meter beam on the top.  When we pulled in and parked we were on 2 meters in two minutes. Getting the dipoles up for 80 and 20 took some time, most of the time all the trees were gone after a tornado. We were on the air the night of Y2K, we were in a small town in southern Minnesota.  On 80 meters we were able to talk directly to the Governor’s office in St. Paul. and you know how bad the bands were that night, everybody was on.

Some of the radios

WE worked with several search and rescue dog teams looking for missing persons that is where the FRS radios came in handy because none of them were licensed hams they could not use 2-meter handheld.  We did get our county sheriff to give us a county radio number and we had a police radio in the van that was used several times. We responded several times after a tornado had gone through and there was nothing left.  The Red Cross was all ways glad to see our van because they knew we could send free radiograms for people and we sent thousands of them. IF you are going to do that, you NEED to have your forms printed and they have to check what message they want to send. they were printed what they had a choice of, we had things like……We are all fine the house did have some damage or  We are all fine house is ok the message needs to be pre-printed because if not people tend to get way too long.

More of the radios

We could run all the gear from batteries or some from solar and all from a gas generator.  We had two 45 amp inverters and one 75 amp inverter if the sun was down and the battery banks dead we ran from the generator.  IF we needed to use the electric heat then we needed to run the generator so we had 220 volts. We also put an AC unit on the top, that needs 120 volts AC so the generator was needed for that.  When we responded to an emergency we had everything with us we needed to run for four days right down to the toilet paper. Gear, tools, spare parts coax, connectors, all kids of wire and rope. Two pop up ten by tens with sides, tables even a ground rod and food and water and soda.  The rig did have a microwave oven for hot dogs and burgers and soup. The only problem we had was there was no place to sleep! So the ten by tens were used for that. It worked but could have been better. Most of the time when the van was out it was the same three guys who went they were all retired and had the time to go.

In the unit

The states of Iowa, Minnesota, and Wisconsin decided to have an emergency drill on the Mississippi River.  The plan was with all the diesel fuel and fertilizer that was being shipped up the river, Teresa’s got their hands on it and set it off and that took out a lock and dam on the river.  We had meetings for six months about how they were going to do the drill. Their plan was to use the VHF radio at the lock and dams to communicate with the mobile units. We tried and tried to tell them that that was not going to work.  We tried to tell them that their VHF signal would not be able to reach the mobile units behind the bluff. What do we know? At the last meeting, we did convince them to give us one of their radios to have in the com van. On the day of the drill we parked in a park overlooking the river, not only could we see for many miles we had radio communications for man miles in all directions.  IT was a good thing we had one of their radios because we ended up relaying all of the communications. The other problem they had, when the Teresa’s blew the first lock and dam when that wall of water hit the next dam downriver it took that dam out so they had no VHF communications. Or that is what would have happened in the real world. When the drill was over and the final report was written, ham radio got five words on the bottom of the last page.  If it wouldn’t have been for ham radio they would not have been able to have their drill.

Ernie Martin in the Navy (a few years ago 😉

The radio gear has been removed from the van but the inverters and all the wiring is still in both DC and AC.  All the fuses and circuit breakers are still in. The van is for sale if anyone is interested. Send me an email at    leewalt@powerbank.net 

We did all that with NO federal or state money! We raised all the money to do the work and buy all the gear by selling hot dogs, popcorn and burgers with NO help from the local chamber of commerce they just made it hard for us. In an emergency, we must all stand together no matter what our little differences maybe, in emergency hams will stand side by side to help. This gave us more autonomy to do what we felt was right. It is hard to describe how great it felt and how rewarding it was personally to be working together on a project like this to help our community.

In an emergency, hams are there to help. We will all stand side by side. There will be many jobs to do, not all of them connected to the radio. In some emergencies, I have been asked by the police to direct traffic. In other emergency’s I have been asked to help with the cleanup. Whatever we are asked to do we do it with a smile. We have worked with several dog search teams, whatever we do we are not there to be the news, most of the time we are behind the scene and out of sight. 73’s WØAUU

Some questions and answers with Ernie Martin:

Q. Why did you create the van?
A. Our ham radio club could see there was a need for emergency communications when we went to our first disaster and the Red Cross had no way to send messages to people in other places. The phones were out no cell phone when we started the van and we knew the ARRL had emergency message forms. WE could see that there was a lot of equipment needed. So one by one as the club had m money we added the gear that was needed. When we were done we had 80 and 20 and 2 and 440, FRS, ATV on 2 meters, aircraft and Mississippi river tug boat communications and radio for police communications and even satellite communications that the Red Cross used several times.

Q. How did you create it? and how did you fund it?
A. Well as you can see it took a ton of work just to get it ready to drive! The steel studs in the sides were all rusted off and it needed to be rebuilt from the ground up. No one in the club knew anything about bodywork so we just started working. As you can see it turned out great. Ask of the funding was done with popcorn, hot dogs and burgers! That took a tremendous amount of work! We went to every town event for miles around

Q. How was it to be of service to support traditional emergency services?
A. We had a county radio number from our county sheriff. With that radio, we were able to talk to the sheriff, police and fire and ambulance. We had a mobile 2-meter repeater in the van and that was used at all of the disasters we went to

Q. Can you share a few stories about how it was helpful?
A. The Red Cross liked to see us arrive so we could send emergency telegrams for the people that were effected by the disaster. When the Red Cross did their damage assessment they used the FRS radio in the van, we had a much better antenna than they did so we had better communications. When we were at St. peter, minnesota, the storm had taken down their AM radio station tower. They were crying OH IF we only had our radio station. We asked them what had happened to it and they told us the storm took down the tower. I said no problem we can build you an antenna and they all laughed at me. I got several guys out, some were to get me anything that could be used to make an insulator. other guys had the job to get me wire, any kind of wire. We had them get the station engineer there and from him I got the frequency. Now that I knew that I could figure the length of a dipole. On the AM radio band, I knew it was going tone very long. That antenna zigged and zagged up and down the street for several blocks. When we connected the coax to the center insulator we told the station engineer to fire it up. He didn’t think it was going to work so he gave it very little power till he could tune it, then little by little he turned the power-up. They found that it really did work and that they had a larger coverage area than their tower did. Now I know the FCC requires the AM radio stations to use a vertical but I thought this was an emergency. As soon as their tower was back up they used it

Q. How and/or why did you retire it?

A. It happens to all clubs the members get older. Some tased away, some moved away, it got down to where there were just not enough of us to do it any more. Our youngest member was 70. That was five years ago. The van has been kept inside all the time and still looks as good as it did on the outside. It would be a great emergency com van for three stations, we had to much gear in but everything was used. It would work really good for one rig on 80 meters and one on 2 meters. There is one thing we wish we would have had and we were working on it, that is we wish we would have had a good vertical antenna one for 80 and one for 20. When we got there there were no trees left so putting up a dipole was hard. We would go around and find broken 2 X 4’s, nail them together to get the dipole up and lucky if it was ten feet off the ground but it worked. WE built some very heavy duty dimples they were made out of lightning arrester cable. We had a spool of 500 feet of rope but used the rope that had already been cut but if we need more we had it. A coffee pot would have been great to have, we made coffee in the microwave oven.
