The credit, or blame, has to go to Warren VO1KS for telling me about this great little SDR receiver. The RTL SDR dongle is a complete wideband receiver covering 25MHz to 2 GHz with no gaps. It simply plugs into a USB port and with some free software and a few head banging sessions it works great. No seriously, the installation was not THAT hard but does require a little work. You need to download three dll files and paste them into the SDR directory after you install the free software, download another program to allow you to replace a driver, and press the right buttons to get started but after that it is a snap. The receiver is available on Ebay for less than $20 and comes with a cheap little 800MHz antenna. For now I just cut the antenna off and wired the end to a BNC to allow connection to a real antenna. The antenna input to the dongle is a tiny little MCX connector. I spent most of today just playing with it listening to some ham repeaters, aircraft comms, fire departments, and some misc. 800MHz stuff just for starters. It works very well on the FM broadcast band and I even heard some 10/11m DX. It is multimode with AM/FM-narrow/FM-wide/USB/LSB/DSB/CW/and a few ECSS AM modes.

I ordered a couple extra of those SMA-N chassis connectors just to have on hand and because the price was right.I also ordered an extra cable of each type for the same reason. Lots of fun so far and can`t wait until the HF converter arrives.Here is a screenshot of what the main screen looks like.
