We have a small club that runs 2A with a GOTA station. We run one phone and one
CW station on dipoles strung end-to-end in trees. Ends are separated by 30-40
ft. GOTA runs a 43 ft vertical with an SGC 237 remote tuner about 100 m away
I bring out my TS-930S *with an INRAD 6 k Hz roofing filter on the first (40
MHz) IF.* The rx holds up fine. My TenTec Orion II does as well. In fact any of
the older rigs that can accommodate one of the INRAD roofing filters will do as
well as my 930S. TenTec Eagle, TS-590DG using down-conversion... Essentially
any of the top 15-20 rigs in Sherwood's ratings should do well. Otherwise,
attenuation at the rx front end is necessary. 10-20 sB worked with my 930 prior
to the roofing filter installation.
