Fred,

The 'opposite' TX INH topic has been discussed before (and confirmed..?) and
this was relevant to me as a Yaesu FT990 user. However earlier posts from
Eric claimed an amp keying loop is unnecessary with the K3/K2 and a modern
amp.

Yesterday I put K3 0145(!) on air with my Acom 1000 amp and can confirm (and
concur with Brendan Minish EI6IZ) that the K3 keys this modern amp perfectly
in full qsk with just the straight key out connection. Note also that the TX
INH feature is described under Transverter Control in the manual, not under
amp keying.

The K3 is a great radio; the problem for me now is my 30A power supply
sounds like a worn out vacuum cleaner when it kicks in - any suggestions for
a nice quiet p/s available in the UK...?

Also is there no easy way to reference earlier posts in the archives here?
Yahoo groups number their posts which makes cross referencing quick and easy
and something like that would be handy here (as above.....)

73,
