 RADIOHF - TenTec Omni 545 with Digital Readout FS  

TenTec Omni 545 with Digital Readout For Sale:
-
The 160 thru 10 meter HF transceiver is technically
an Omni 545 analog. However, a frequency counter
has been added, so that it now has a digital readout.
So it is basically similar to an Omni 546.
-
It produces about 100 Watts and has a very good
receiver. An audio CW filter is built in, which
is extremely effective.
-
This is a "Series B" Omni.
-
Cosmetically it is very good, but not mint.
Everything works as it should.
Buy the rig with the counter and manual for
$300, plus shipping from Florida.

Thanks. 73,

 RADIOANQ - FS: 275V regulator 4 516F-2 and PM-2 PS  
Due to old 1956 design of 516F-2, or PM-2 power supply for Collins KWM-2 (A) or 32S series transmitters runs on 125V AC power Voltage, the 516F-2 supply should deliver 275V Low Volt becomes 330V Plus minus during receive mode of KWM-2(A), vacuum tubes get 330V which will shorten life of tubes and cause extreme hot temperatures affect other parts. KWM-2(A)and 32S series transmitter get lot of heat problems. I have a solution to keep the LV to exactly 275V either transmit or receive mode.Using 500V MOSFET and series of Zener regulators,LV is now tightly regulated which helps keep the VFO with no drift and no audio hum as it works as ripple filter.The board is 22mm x 30 mm by size, made with SMD components and can be fit to the sidewall of power supply. Price is $40 plus $6 for USPS. two or more it has to be shipped by priority, price is $13.check to my QRZ.com address.Other output V,150V or 250V or 300V if needed.
