Yaesu 7800 TNC

ginericLC · 10-28-07, 04:32 AM

Anyone use the TNC for packet? I’m curious as to how it works. I sold my Kenwood TMV7A yesterday as it won’t work in the 100. I can get the 7800 for 229.95 with the remote head kit before the 31st. It looks like a great radio for my needs other than being able to do the APRS. However, I have a Tiny Traker 3 that I could plug into the TNC to do the APRS. My big question is can I leave both hooked up and have them both running at the same time?

No... if you are doing APRS you need you radio tuned to 144.390 for each of your becons. You can use a TNC with the radio but not at the same time as you are using it for other things.

I have a second radio to do APRS becons and if I won't to see where everyone is around me I plug my laptop and TNC into my primary radio and change to the 144.390 but it will only receve when I am on station.

I agree. It is one or the other and not both.

Could probably only do that with a radio capable of dual receive or cross-band repeat where you have 2 separate tuners. The 7800 doesn't have that.

Would the 8800 work for that?

Not really... I have the 8800 and you can only send on one side or the other... You can set your radio to TX on the APRS side and listened on the other but if you wonted to switch sides and TX on the other you would have to turn off your your APRS transmitter first so you don't send APRS burst over the other station...

Hope this helps,
