I installed KPG-49D ver. 4.02 and it worked beautifully. It connected to the radio, had all the options I needed, and now my radio is up and running. Thank you all for your suggestions!

UPDATE: After various failed attempts, I think I have finally found the right approach. HAMVoIP using IAX to communicate between my remote device (phone, laptop, etc.) and the HAMVoIP server (Asterisk+Allstar). I am using a direct connection between client and server, so there was no need to register my node with Allstar. For the client software, I am using Zoiper5. At the moment I am only using a test connection in sort of an intercom mode. But, it works. Next step is to modify my USB sound-card to add COS (Carrier detection) and PTT support. I had some fairly restrictive requirements which made this harder than it might have needed to be. First, I wanted to use a simple, inexpensive, single-board computer, like a Raspberry-Pi, at the remote radio site. This pretty much ruled out Zello, which only runs in Windows, or Wine on a i386 Linux board. I spend two days trying to get i386 emulation and Wine working on the Pi, and finally gave up. It just won't work on Debian/Raspian Buster. The next step was Asterisk with Allstar. I first tried using a special Raspian (RasPBX) image that came with Asterisk and FreePBX. That installed, but getting Allstar (apt_rpt) to work was pretty much hopeless. There is almost nothing on the net on how to do that. And then, finally, I found HAMVoIP, this is a special setup of Arch Linux with Asterisk+Allstar installed, and a simple config system. That worked. On the other end, I want to use my Macintosh as the client. There seem to have been a number of soft phones for OS-X around 10 years ago, but almost nothing now. And, I needed IAX support as well to talk to the HAMVoIP server. But, Zoiper5 solved that problem. Anyway, now that I have a working core system, I will take the next step to actually controlling a radio. Stay tuned...

Update. Installed yagis on both ends. We can understand every word on every channel now. Next phase, raising both by 6 feet and make sure the aim from mine is good. I was actually out on the roof in my underwear re-aiming it just now haha. I did the map aim and drew a straight line but didn't have a vantage point for beyond my house, garage roof mount on existing dish antenna j mount with a piece of toprail that probably barely clears the apex of the main roof, and it may not, didn't get on main roof to look. I think I'm close to aimed but I don't think I can get much improvement with a little more height. Stay tuned

I've been using this for simple line of sight. https://www.scadacore.com/tools/rf-path/rf-line-of-sight/ I like it. I'm sure the gmrs yagi is the way to go, I was just trying to save some time and money finding a dual band. The tram showed pretty low SWR for gmrs frequencies but the performance on gmrs is so so, I think. I did try to hit a standard uhf repeater in the area and was able to hit one about 25 miles away with it. If it stays sealed up, I think it's a keeper for a standard dual band omni.

I can confirm KPG-49D version 4.02 from ham files works on windows 7 installed normal with no issues also just uninstalled and reinstalled with no issues

I just purchased a BTECH 50X1. Every time the power is turned on or turned off, it emits a horribly loud beeping tone. In Gods name, someone please have some idea how to eliminate this noise. I am very hard of hearing. I spent my Naval career working the flight deck of an Aircraft Carrier. I spent a lot of hours standing next to very large Jet engines at full afterburner while waiting for them to be catapulted off the pointy end of the ship. I have to cover my ears before turning this dang thing on or off. It physically hurts my ears. Did I mention the crap I am taking from my wife. Oh Yes, I am taking a lot of crap from her over this noise. She refuses to turn the radio in the car on so we can have communications while she is out running errands because the noise scares her. Volume control has no effect on the radio or the wife. Shouting at it has no effect on the radio, however the wife... Well that's another topic. Throwing things at it has no lasting effect on the radio, again, the wife.... Well not a good idea. Placing a pillow over it and sitting on it during the insertion of elimination of power seems to be the only effective way of reducing the volume at this point. Radio quiets down, however the wife......she threatened to call the cops if I did it agian. So as you can see, I am at my wits end. Anyone have any ideas how to get rid of the annoying beep. I'm keeping the wife, it's her money if you get my drift.... Dan

I guess the wife is smarter than I am.... She proved to me that the volume does in fact eliminate the beep if you have it turned down all the way..... I don't know how I missed that, but I feel really stupid now. Well the wife's happy, so Happy Wife, Happy Life.... I'm good now. See Ya on the Air Waves.

I have the V1 the 701c and the 771. The 701c is supposed to be tuned for 150-165 and 450-470Mhz so it should help with the transmit by sending out more RF. I have not seen a noticeable difference on the receive side and that is what my V1 mainly does. Guess its time to set up a transmit test to see if there is a noticeable difference. A better tuned antenna should yield a longer transmitter life so that alone would make it worth the $15.

Hard to carry a 10 foot antenna hiking. BTECH recommends if you are going to add a different antenna that you use the 701c, not that you need a different antenna. I was hoping to gain some information here. Looks like that may not be possible.
