[amsat-bb] Modern Equipment Matrix

[Patrick STODDARD (WD9EWK/VA7EWK)]

Clint,

Thank you for your positive contribution to this discussion thread with
your question. As you know, the list of radios currently in production
that support full-duplex operation on FM satellites (going from KE9V's
original message) would be short. If we limit the list to those able to
work SO-50 full-duplex, transmitting on 2m while simultaneously
receiving on 70cm, there is one HT:

Kenwood TH-D72A

a few dual-band FM mobile radios:

Yaesu: FT-8800, FT-8900 (I haven't tried the newer FTM-350/400 yet)

Kenwood: TM-D710, TM-V71

Icom: IC-2730A, IC-2820H (I haven't tried the ID-5100 yet, and Icom
America still lists the IC-2820H - a radio I use on FM satellites)

Alinco: DR-635 (I haven't tried the DR-638 yet)

and the two satellite-ready base transceivers:

Icom IC-9100
Kenwood TS-2000

This doesn't include using two radios to make a station capable of
full-duplex operation on SO-50. I have not tried any of the 2m/70cm
FM mobile transceivers that are coming from China, and - as far as
I know - I have not seen any reports of those radios being able to
work SO-50 full-duplex.

Not all of the rigs listed in other posts are "20-year-old ancient rigs",
as you characterized them. Some came on the amateur market after
1995, but yes - they are no longer in production. Since many of these
radios are still considered good performers on SO-50, why not include
them in the discussion?

Andrew KE5GDB took a stab at compiling a list back in 2009. His
web site no longer has that page, but the Wayback Machine cached
a copy of it from back then:

Other radios, in particular HTs like the Wouxun KG-UV8D in current
production, and many others like newer versions of the Icom IC-W32A
that have gone out of production, should work fine with the upcoming
Fox-1 satellites that use a 70cm uplink and 2m downlink - reversing
the uplink and downlink bands as used with SO-50.

73!
