Hi Wolf,
Thanks you for your comments.
Are there any circuits available for this type of transverter please ?
The annoying thing is that I used to have an IC706 & sold it when I gave up
mobile operating but before my interest in LF.
So yours is a 1st model, then that would make it a much better purchase
option with lower price when I find one.
Probably have to sell the JRC NRD-345 receiver first.
Cheers,
Gary - G4WGT.

Hi Gary,
I use an IC706 (first model) for my 136 kHz transverter, and it works like
a charm (with the CW filter of course).
The nice thing about this radio is, all oscillators are derived from a 30
MHz master oscillator, which can easily be synchronized to the 10 MHz
OCXO. In my tranverter, this OCXO drives the transverter (10.136 MHz <->
0.136 MHz), so everything is driven from the same reference.
I didn't check if the IC706 can be modified to generate a signal at 10.503
MHz (+/-). If so, it could be used as a duoband transverter for MF+LF,
using the same mixers, only different bandpass filters in the frontend.
Cheers,

Hi All at LF,
There has been mention in the past on the LF group of LF & MF
operators using Icom IC706 as a transverter driver due to its
frequency stability, how many of you out there use the IC706
this way & is the receive capability good on 136 & 500 KHz ??
I am considering selling my JRC NRD-345 receiver & moving on
to a linear system for LF & MF employing a transverter driven
from a HF transciever like the IC706.
Any comments, ideas & circuits etc on this subject will be much
appreciated.
Thanks in anticipation.
