National NCX-5 MK 2/ Nice rig: National NCX-5 MK II $350 W matching power supply in kinda sorta working
The radio receives, and the radio transmits , The transmitter puts out over 100w on 80m down to maybe 60 or so on 10m. It is in need of an alignment as the receiver is sensitive on the CW portion of the bands and the phone portion. In the CW portions, it's actually a pretty hot receiver. RF gain control is scratchy but works
. The part I could not get dialed in was the rx/xmt alignment. xmt frequency was always off by maybe 300 hz from receive. This is a known issue with these radios and can most likely be overcome by someone with the proper knowledge.
The power supply works as it should.

Hammarlund HQ-110 for Sale: Hammarlund HQ-110 for Sale. And Original Optional Speaker.
Radio Works. Clock also works and keeps good time. I am sure radio needs an alignment. The Manual (copy) has a pretty good procedure for it.
I have had the radio for almost 20 years. Bought it from the original owner. Visually in good condition.
The "cal set" knob is missing. Its a very small knob. Between the two frequency displays. Everything else is there. More Pictures available.
I am thinning the herd, before that final retirement.
Make me a reasonable offer.
Located in South Aiken County, SC
Thanks for looking.
