Garey, Thanks for your answer. I think I will just use the linear on my other
rig, which is a Yaesu FT 1000 MD V. Sincerely, Boyd

Probably not. The problem here is that the PiNet output circuit is
designed to match the plate impedance of three tubes to ~50 ohms. By

Garey, I know we need to leave all the finals in on a TR-4 because of the
series parallel filaments, but could one leave the plate caps off one or two
tubes to cut the power output instead of using a power reducing network ? Boyd

Garey, I knew if you would answer you would know. I think you are right about
the db diff in 300 watts. Not very much so may not be worth it. Thanks, Boyd

There is a set of N.O. contacts on Pins 5 and 8 of the Jones connector
that close on transmit that can be used to ground the relay in the
Ameritron.

There's an output on the power supply, which is 120V, which you could drive
a relay with to switch the 12V.

Could someone out there help me with the interface to use between my TR4-C's
and the Ameritron AL-811. The ameritron has its own Transmit/Receive relay
which uses 12 VDC at a 100 ma when grounded. Is there anyway to use the ALC
circuit on the Amp with the Drake ? Boyd W0BUW
