IF frequency range for Transverters
Posted: Sun Sep 12, 2021 6:56 pm
Hello all,
A new Anan 7000 DLE MkII owner here and new to the Apache Labs community. So far I'm very impressed with the hardware, software, and the supportive community!
I'm testing the waters of VHF operation with one of the Ukrainian 2-m transverters, so I'm trying to get everything set up properly. I ordered the transverter for my prior radio and got the main frequency at 146 MHz with a 28 MHz IF frequency. Using an offset of 118 MHz and the 10m band as IF, it all seems to work well above 144.46 MHz. Below that, all signal drops out. That translates to a bottom end of 26.46 MHz in the IF.
I was able to use the 12-m band as the IF (under the Antenna setup tab) and it covered up to about 145 MHz with the transverter.
So my questions are:
1) Am I understanding this issue correctly or am I missing something in the operation of the hardware or software?
2) Does anyone know the frequency ranges by band supplied as the intermediate frequency for transverters?
3) Is it ok to run with multiple bands selected as transverter input under the Antenna setup?
Thanks for all the help. I apologize if there's existing info out there on this topic...did my best to find something but had no luck.
Thanks,
Tom
