 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.

 RADIOHF - Elecraft K3/100 with accessories  
I have for sale or trade a very nice Elecraft K3/100 rig s.n.#808 along with a P3 panadapter s.n.# 3461. Both the rig and the P3 work as they should with no issues and are in excellent condition. The K3 was just aligned and upgraded to version 5.67 by Elecraft. Included is a Yaesu MD 100A8X desk mic with the correct adapter cable for the K3. Also included are the manuals, power cables and all connecting cables. The rig has the gold pins installed along with the KAT3 100 antenna tuner, KPA3 100 watt amp, KRX3 sub receiver, KXV3 and KIO3 I/O boards. The main board has the following filters installed 2.7, 2.1, 400, and 250. The sub receiver includes the 2.7, 400 and 250 filters. The equipment is from a non smoking shack and there are no nicks, dings or scratches. Additional pictures are available upon request. I will insure and ship the station for $1900. I accept USPS money orders as payment or would consider trades for HF equipment of equal value.

 RADIOHF - Drake C-line  
PENDING Sale…Very very clean Drake C line. R-4C with no extra filters, T-4XC, MS-4, AC-4. Excellent cosmetics on all units 9+ of 10. I have owned this C Line for twenty five years. Have used the R-4C / MS-4 recently. Am using my TR-4C more so havent used the C Line much over last few years. Hate to see it just sit there. Had a family member pass suddenly last month and have had to clean out her things. Now I think I need to reduce the number of radios, etc. so my XYL won’t have to! All units work but AC-4 has never been recapped. R-4C missing the silver tuning dial insert plate. Otherwise fine.
Prefer not to ship but will on your dime. Would need 4 boxes.
$550 for all plus shipping if needed. PayPal (you pay fees), MO or cash or personal check (ship after clears). I don’t think you will be disappointed. But no returns, as-is sale. Thanks for looking.
More photos upon request.

I could list all the features of this radio but if you're reading this you already know about it's capabilities. If not there's lots of data on the Internet. requires 12VDC for operation (not included). I believe the headphone jack is not working properly. Works perfectly on headphones or external speaker. Internal speaker is intermittent.
PRICE $399. SHIPPED (USA). REAR PHOTO AVAILABLE - JUST ASK.
