Hello Gary.
Here I am using often my Icom 706 version
MK2.
On 630 m it delivers 1 to 2 Watts output
when you set the minimum power level "L". The PA TX radiator
stay a bit warm but not too much during long transmission as
OP8. Do not try to set an higer output
level because the PA may be becoming very warm.... An amator
said that his 706 MK2G can deliver 20
Watts ??? Perhaps there is some difference between the 2
versions ? The basic stability is nice for WSPR2, OP8 and
QRSS 3 and 10. But here I installed the OCXO option and with
it I can copy QRSS 120 on LF with no perceptible drift. I
highly recommand to build and add an external 5 poles low
pass filter to have a very nice sinus signal shape.
On 2200 m the PA stays cold but the
output power over 50 Ohms is low, about 5 to 10 mW. Also
nice shape signal if you add an external LPF filter.
This transceiver is also very sensitive
on MF / LF reception an has also a great advantage : only 1
Hz step using the VFO !

Subject: LF: Icom IC706 on LF/MF
Hi all,
I recall some while ago it was mentioned that the Icom
IC706 could
produce a low level of LF & MF on Tx.
Which version was mentioned or will all IC706 versions
produce output at
these frequencies ?
Thanks in anticipation,
73, Gary G4WGT.
