Good Morning All,

Fivedash has a built SDR receiver offered for sale that is based on the HF RX II receiver. This built receiver board, called the RX Handy, covers a single range such as 4 MHz to 8 MHz for 80m and 40m band coverage. (Other ranges are possible, even 630m.) The RX Handy receiver is a simplified HF RX II receiver circuit design and doesn't require a 12 VDC power supply for operation since all circuits on the RX Handy are powered by the 5 VDC provided in the USB cable plugged into the board. Cables plugged into the RX Handy receiver for normal operation are just the USB plug, the stereo audio output plug and the BNC antenna. The down side of powering the RX Handy from the USB 5 VDC is more center frequency noise, about 3 kHz on each side of the center frequency.

The built RX Handy receiver board is a useful HF receiver for casual operation, I typically have on playing every morning as I work on various projects. The various 40m SSB nets make for easy and often interesting listening as I work prior to breakfast. Several who have tried the RX Handy receiver have spoken well of it.

This week's project was to take a several year old partially built 6m/2m receiver prototype board, strip off the unused components and build an RD Handy receiver on the board. The old receiver board is the same size as the RX II board and is now playing nicely on 40m. If anyone would be interested in trying an RX Handy receiver, this salvaged receiver is available for $20 post paid to a US customer. Just contact me directly by e-mail.

Best regards to all,
Tony, kb9yig

I am still actively playing with an designing things with the soft rocks. I would be interested in obtaining one of your new handy receivers Tony!

Have a good day!

Hi Guy,

Built RX Handy receiver boards for the 80m/40m band group, (4MHz-8MHz), are available on the Fivedash.com website. Multiple receiver boards are in stock for next business day mailing.

If you are wanting a less expensive copy, one built on a reclaimed receiver board, I will look into my past projects box to see if I can find another receiver board to reclaim.

Regards,
Tony, kb9yig
