Hi Martin ,
I am using a rather old
Kenwood TS940 with Dave,s pre- amp which performs very well with a built in 270
Hz crystal-filter combined with the built in Audio Peak Filter which reduces a
lot of noise .The S-meter calibration will be 50 microvolts for S9 if you put an
adjustable attenuator ( a simple potmeter will do ) between the pre-amp
and the receiver .
I think this goes for a
lot of other tranceivers as well like the TS430 and TS440 with CW filters built
in and outside Audio Peak Filters . I also tried the G0MRF preamp in front
of a Yaesu FT847 but the 847 is so deaf on 137Khz. that the gain of the pre-amp
is insufficient which is a pity as the receiver of the 847 is doing a fair job
with the built in 500Hz Mech. filter in combination with the adjustable bandwith
control in the LF DSP on the HF bands .
73,William
