 AMPHF - FS: SPE Expert 1.5-FA Amplifier  
I bought this amp used, direct from Bob Hardie, from repair work replacing the final. I've never taken it out of the box except to take pictures and thus never used since the repair. It has the ATU also. It's in mint condition with original box, carrying case, CD, warranty card and extra air filter. I believe it is a series 1? These sell new for $5995 now. Asking $4150 shipped. Contact info good on QRZ.

 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
$285, plus shipping from Florida.
-
Thanks. 73,

 RADIOHF - For Trade: Yaesu FT-1000MP MkV  
Looking to trade my MkV for a portable QRP rig. Something like a KX2, KX3, IC-705, FT-817/818, FT-857D, etc. Radio works perfectly, 200w all bands all modes, and has the narrow SSB and CW filter. Not sure which ones as I would have to pop the cover to check. If interested I can do so and check. I would also consider a trade for a TX-500.
Face to face deals only. I can travel a reasonable distance from 32084 to meet. Email or text only please.

 AMPVHF - FOR SALE: W6PO 2 meter amp  
This is a well built W6PO designed amplifier employing "plumber's delight" tubing for the resonator tubes. A turns counter operates the Plate cap. The load cap is adjusted from the rear panel. Adjustable input matching provides for fine tuning of the input SWR. An Omron Technologies Time Delay Relay provides proper warmup for the 8877 (3CX1500A7) tube. The RF deck is mounted in a rack mount case that sits atop a custom built roll around cabinet. The high voltage transformer and filter caps are mounted in a separate housing sitting inside the cabinet. High voltage is manually controlled by a Variac. The amplifier is wired for 240 AC voltage. Driving the amp with 35 watts easily produces a 1KW signal. 45 - 50 watts brings it to full legal limit. Asking price for this amplifier is $1100.00.. This amp cannot be shipped, pickup only in Elkhart, TX. For additional info, contact me by phone or email only, no texting.. Tnx, Nick KM5FL.
