Nye RFM-003 3kw meter $ 375.00 shipped: I have a very nice Nye Viking RFM-003 3 KW power/SWR meter for sale. It has the 3 KW coupler. It comes with another remote meter unit that is very very nice looking with the swivel mount but I tested it and it does not work out of the box so it will need troubleshooting. My plan was to eventually get around to fixing the second monitor unit but I ended up buying a used Tele Post LP100A which I like better so now offering this RFM 003 package for sale for $ 375.00 shipped lower 48. The meter is pretty slick since you can monitor peak or AVG power and can monitor SWR or reflected power. The meter has back lights which is handy. It works 100% perfect as it should except for the 2nd meter unit will need some troubleshooting to get it online. Pay Pal preferred. Lane ku7i.

Alpha Amplifier for sale or trade: SALE PENDING. ASK ABOUT FREE DELIVERY!
Very easy Legal Limit with this amp with quiet qsk pin diode switching. The 86 used 2 Eimac 3CX800A7 tubes and these are in excellent condition with low grid, low current, 1500+ output. There’s nice circuitry protecting the amp against high swr/wrong antenna mismatch. It’s been with me for a long time but is being replaced with a solid state amp that I can remote. I entertain trades, partial trades, cash offers.
The picture shows 1500 out into my 40 meter rotatable dipole without an antenna tuner.; Listing #1734857 - Submitted on 07/03/25 by Callsign N8KR, Modified on 07/08/25 - IP: 50-104-73-57.prtg.in.frontiernet.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
