For using the Kenwood TS430 as a VFO to go into the Knight T60, yes
you can use the AM mode with audio gain turned down on the TS430 and put a
dummy load on the TS430. I don't remember what voltage is required at the
T60 input. My guess would be 5 - 10 volts PTP but it has been to long

properly on AM, will get you better signal and audio reports and keep your
band neighbors friendly.
Thanks for the
Hey Jack:
From years back when I worked around broadcast stations I always wondered
about the plates of the modulator and finals being so red that I commented
to an engineer. He just laughed and said not to worry about cherry red. It
is when they get white you should worry.

Hello Jack,
Controlled carrier has tradeoffs. You are trading reduced linearity and
tricker audio adjustment for greater PEP. Not that it can't be done and
sound reasonably good.
Another point is that tubes with zirconium or titanium on the plate NEED to
get red to getter properly. I'd

Jack,
Others have commented on their thoughts concerning carrier control. One
suggestion I have not heard however is to reduce the amount of carrier control
to no more than 3 db. This might be the ticket to gaining linear amp efficiency
without the nagging extreme carrier pump common to
The transverter socket has nothing to do with the output relay switching.
There is another socket for external switching (such as a linear) but be
careful if you have 120 VAC relays, they should be keyed with another relay
in between the two connections.
On second thought, maybe the attenuator
Hello Jack: My TS-430 works OK as a VFO. You should make a 5 to 10 Watt
attenuator to insure that the output is terminated correctly. A better way is
to use the Transverter jack (socket) on the back of the 430. The
output level
is only 50 mW and is 50 Ohms. The transverter output may not
You can also use one on a broadcast transmitter

Guess I had better get out the manual. Have no clue what a transverter is.
Good luck and be sure you are in CW mode (no Mics!!)
How bout AM with the audio turned all the way down? CW
