Why yes, I have one 70cm turnstile for smaller animals like squirrels and a 2m turnstile for larger animals like opossums and raccoons.

No just me having fun playing radio.

I am working on a satellite project. I have two turnstiles that I will mount in my attic. Each antenna will connect to an 5w HT which will then connect to a Digirig connected to my computer. This will be an always on installation so I will be using a battery eliminator for each radio. Any suggestion on what HT to use? As suggested by the title I am looking at the TH-UV88 and the GT5R which both have an available Battery Eliminator. Thanks, Robert

Thank you for the suggestion of Radio Mobile. It is interesting to compare results from both sites.

At our last ham club meeting we had a presentation about terrain assessment and antennas. The website https://www.heywhatsthat.com was brought up. You can put in your location your antenna height above ground and see how far you can "see". Because of my location, I can hit repeaters east of me with not much height but I found out I can put an antenna at 50 ft and still not go west.

It it is everything but a computer.

Here is what I came up with: $16.88 2 K-connectors $79.98 2 Radios https://www.buytwowayradios.com/tyt-th-uv88.html $29.98 2 battery eliminator https://www.buytwowayradios.com/tyt-tyt-elm-uv88.html $80.00 1 Interface box https://www.masterscommunications.com/products/radio-adapter/dra/dra30.html So a bit over $200

Allstar and Echolink are both ways that analog repeaters can connect to each other through the internet. The node I am building will just a very low power in house repeater connected to Echolink and Allstar. Echolink also has a computer app and a smart phone app that allows you to connect to repeater without having a node.

You setup the radios on different bands. One radio on 70 cm and one on 2 meter and the transmitting radio on low. Specs say one watt but most likely less so there shouldn't be an issue.

The next project I plan on doing is a dual radio Allstar/Echolink node. http://allscan.info/docs/diy-node.php I am planning on using two RT85 or TH-UV88. I realize they are clones. The plus to the TH-UV88 is that there is a battery eliminator for it.(Using the same battery eliminator on the RT85 is hit and miss) The plus to the RT-85 is that it is cheaper when you buy a pair. My question, for those who have used both, which is a better quality radio? The reviews for the RT85 are better but is that true? Thanks

Michael I think you are on to something. I could take the 4 remaining wires wire those to a female RJ45 jack and splice into power and ground and that should work. The stock microphone would just plug into the female jack. Thanks for the idea.

I received the SM-01 microphone and foot pedal yesterday. I did have to rewire one connection. The PPT connection was different between the microphone and the radio. The other 3 connections were the same. One thing to note you have to do ground wire to ground wire and not worry about the mic ground for it to work. To fix the PPT connection you have to wire the orange striped wire that connects to the radio to the brown stripe wire that connects on the microphone assuming you are using a T568B coded Ethernet cable. Of course you could just cut off an end and reconnect an end with moving the PPT to the correct spot and crimp on a new end. I didn't have any RJ45 connectors on hand so I did a splice in the middle. I tried the microphone out today and people said it sounded fine. The downside is you lose all controls on the microphone but if you need to be hands free it is a nice trade off. Thanks again for everyone's suggestions.

I finally found a pin-out for the radio. https://www.project-ats.com/connecting-to-anytone-at-779uv/ Retevis said the SM01 was incompatible but I wonder if it would be if I made a made a custom cable. I am thinking the incompatibility is the cable not the mic itself. I do have one question. The radio has a ground and a mic ground and the SM01 has a ground. Which grounds would one connect? Should the SM01 ground be connected to the ground or the mic ground of the radio? Thanks

I asked Retevis if I could use the SM01 with the radio using the RJ45 cable or would I need to make a custom cable? I received back that the the two are incompatible. I assume the issue is all the control buttons on the stock microphone. Thanks for all your help.

I just realized something tonight. The Retevis RA25 is the same hardware as the DB20G / AT-779UV. I just sent an email to Retevis tech support if the radio and microphone are compatible since the carry both. I'll let you know what they say. Thanks again to both of you for your help.
