The Icom IC-7800 is a high-end HF/50MHz amateur radio transceiver that was released in 2004 and has since been discontinued
. It is considered a benchmark in amateur radio design, a pinnacle of performance achieved through the combination of Icom's 40 years of analog RF circuit development expertise and cutting-edge digital technology.

- RADIOANQ - For Sale: JRC NRD-515 HF receiver
- SALE PENDING: For sale is a beautiful JRC NRD-515 HF general coverage receiver. Other than a very small black mark on top of the cabinet there isn’t any other blemish I can find. All filters are installed. I am the second owner. Will come with original owner’s manual and in the factory box. Note that the frequency band spread tuning knob and pot has been changed to a ten turn pot and a small vernier dial, a big improvement over what was a very touchy dial to tune. The original pot and knob was kept and will come with the radio. This is a very popular and highly sought after legacy receiver. Works as it should, it is a joy to hear. AC power cord furnished. Price is $750 shipped.
