Good Morning Group,
So far no one has showed an interest in the 4 MHz to 8 MHz receiver board detailed below. Being USB powered makes it handy to use and with it's Si570 clock any center frequency in the 4 to 8 MHz frequency range can be entered from the SDR programs. The spectrum lost due to the additional center frequency noise is quickly compensated for by entering a center frequency away from the desired signals.
I hate to see this useful little SDR receiver board sitting unused so I will offer it again at a reduced price. The new price is $30 which includes mailing cost to either a Canadian or US purchaser.
If interested contact me directly.
Regards,
Tony, kb9yig

Good Morning Group,
Looking through built receiver boards on the back shelf I find one that
might be of interest to someone. The built 3.5 inch x 2 inch HF receiver
board is for the frequency range of 4 MHz to 8 MHz. It is basically a
single range RX II receiver but is powered by the 5 volt USB voltage. The
receiver kit was developed for use by students, several years ago at the
University of Toronto, in an EE lab for students to build and measure
performance. Powering the receiver board by only the USB 5 volt supply
does result in more center frequency noise, "Christmas tree" pattern, about
5 kHz each side of the center frequency. As I type this I am listening to
this receiver board on the 40 SSB segment of the band.
If any interest in this HF receiver the price is $40 which will include
postage to a US buyer.
Thanks,
Tony, kb9yig

Thanks. I would have tought that its part of V5, but, never saw any
reference to it.
I like the V5 barebones, because I can experiment easily
