[Lowfer] Thanks for information...transverter idea...

[WE0H]

I built this transverter 
http://www.we0h.us/Amateur_Radio_stuff/HF_LF_Transmit_Converter/HF_LF_Transmit_Converter.jpg
and it works excellent with my TS-930's transverter port. I changed the 
HF input to just couple in the transverter signal without all the high 
level attenuator components shown on the drawing. I also added a 7th 
order chevy lowpass filter between the mixer and the opamp stage. Tuned 
for 515kc. It drives this FET amp http://www.500kc.com/N4ICK/index.htm 
with the oscillator stage left out and adding a 74HC244 line driver 
between the 74HC00 NAND and the FET driver IC. This gave me some signal 
shaping to eliminate any ringing after the 7400 IC stage. Everything is 
referenced off of a 3mc oven oscillator.

This is my transverter receive section

I use a modified lowpass filter on the input tuned for 515kc. It makes 
for a super hot receiver good from 515kc down to DC.
