i have built the 38 special with 5watt mod and KC1 keyer/counter. i took out
the original sidetone circuitry from the 38 and use the built-in sidetone
from the KC1. that now eliminates the extreme thump i used to experience,
although i do still experience slight clicks when switching from transmit
back to receive. before, the thump was so bad i had to turn down the rf gain
and use the sidetone in my mfj bencher/keyer. haven't got the counter
portion of the KC1 working yet. i might have to build a small buffer amp to
boost the vxo signal to the KC1. anyone else using the KC1 with the 38
special and got it to work yet? the RIT mod is next. presently, i am getting
about 33khz coverage and work just about everybody i hear with just my loaded
80-10m dipole "laying" on the roof! receive audio and transmit signal are
excellent! i used bill jones ki7ds(?) method of tuning up the transmitter
and it worked real well! just tune another transmitter to your existing
antenna with your antenna tuner for minimum reflected power, then switch to
the 38 special and adjust TC2 for max forward power and min reflected. worked
great, thanks bill!
