I've got a Kenwood TH-F7E and NFM is 2.5 kHz, FM is 5.0 kHz. In Europe we do indeed try to use NFM. 73 de Hans BX2ABT

I have not looked up the deviation for narroband FM, but just choose that modulation method in the Kenwood Modulation menu. It is either FM or NFM. I assume NFM is what is the default in Europe?

Thanks for the link, I hadn't seen that page, yet. As for 2m: I have a nasty local case of interference here which wipes out 145.825 in most directions (local electronic billboard), so I'm not active with APRS. BTW, what do you mean by NARROW-FM? I take it that it is the deviation of the FM signal, with narrow being 2.5 kHz, right? 73 de Hans BX2ABT On 07/06/2019 09:42 AM, Scott via AMSAT-BB wrote: > There is quite a bit of detail on the possible modes of PSAT-2 operation at: > > https://github.com/alpov/PSAT-2/blob/master/README.md > > ... so far, I've seen both PSK31 and SSTV in the 70cm downlink.
