Power Supply — Transmitter — Ed K5KBV — (806) 683-5603
“2.5kv — almost 2.75 kv — power supply with home-brew alterations. Documentation in attached manuals. Transmitter built for Forest Service circa early 70’s.

No band switch or output coils except 20m tank roller inductor. All of this comes in a cabinet, 19” rack with rollers included. In addition, many little parts were salvaged such as bypass capacitors and transmitting caps. Asking $300 for the whole bunch.
Andrews Heliax — Ed K5KBV — (806) 683-5603
“We picked through all that was left at Amarillo Metals and found these good lengths — my fence is about 4 ft. which will give you an idea of the length of each of the rolls. I’ll be checking them out with a TDR to make sure there are no problems. Give me a call if you are interested in some of this hard line.”
“This is used Andrews 1/2” feedline, priced at $0.43 per foot. Fittings for this hardline range from $9.95 – $23.95 on Ebay.
“Each roll has been rung out with a TDR and are in great shape for HF use. The 91ft cable shows a very small anomaly at 29ft from the end which we injected the test. Inspection showed the coax was elongated when it was taken from the tower: return loss is minimal. See TDR plot screen below:”

PushUp Pole PARTS — Ed K5KBV — (806) 683-5603
Ed says “thanks to all who bought a pole. I still have bits and pieces if anyone needs short lengths or repair parts.”
A big THANK YOU to Ed (and RC), from all of us who were able to snag one or more of these great poles for our own QTH — you’ve helped us get a good start on (or add to) our own antenna farms, and we appreciate you!!
