[HBQRP] SDR up-date

Mon Apr 14 09:56:08 EDT 2008

Morning all,
I sent Tony an email asking for the latest info on the 'Soft Rock' kits and below is his answer.
If any of you are interested, just order direct from him.
Item of interest - one of the Pixie related e-mail groups on Yahoo has had notes from a couple of folks using the SRD soundcard software with their Pixie's and are reporting improved ability to pick out signals. Just click on it like in PSK.
Anyone tried this yet? I think I will play with it. Should work..
Have a good week all, see you after OzarkCon, next meeting is May 10th and we will be going to the park for our annual antenna day..!
(mini-field day).

Hi Dar,

The kits now available are listed below:

SoftRock Lite receiver kit information is given below.  Also now there is
the one watt RXTXv6.2 SDR family of transceiver kits.  Band coverage
with each transceiver depends on the sampling rate of the soundcard.  With
48 kHz sampling the band coverage is slightly over +/- 21 kHz each side of
each center frequency.  If the soundcard can sample at 96 kHz the band
coverage is about twice as great each side of each center frequency.

The 40m/30m RXTXv6.2 transceiver kit comes with three crystals to give
center frequencies of about 10.124 MHz, 7.014 MHz and 7.056 MHz.  The kit
price is $31 for US/Canada and $32 for DX.  Mailing costs are included
in the kit price.

The 40m/80m RXTXv6.2 kit has 40m center frequencies of about 7.014 MHz
and 7.055 MHz.  The 80m center frequencies are about 3.507 MHz and 3.527
MHz. Kit price for the 40m/80m RXTXv6.2 kit is $30 for US or Canada and $31
for DX where postage costs are included in the kit prices.

The 80m RXTXv6.2 kit at $30 for US/Canada and $31 for DX includes
crystals to give center frequencies of 3.514 MHz, 3.549 MHz and 3.579 MHz
for band coverage from 3.50 MHz to slightly above 3.60 MHz.

The 160m RXTXv6.2 kit at a price of $30 for US/Canada
and $31 for DX.  Center frequencies provided in that kit will include 1.812
MHz, 1.843 MHz and 1.919 MHz.

The 20m/30m RXTXv6.2 kit is $38 for US/Canada and $39 for DX.  The
kit includes a small daughter overtone oscillator kit to get center
frequencies of about 14.050 MHz and 10.124 MHz.

The 15m/17m RXTXv6.2 kit is $38 for US/Canada and $39 for DX.  The
kit includes a small daughter overtone oscillator kit to get center
frequencies of about 21.0 MHz and 21.05 MHz.
(A search is being made to find a suitable 17m crystal.)

The v6 SoftRock Lite is a single-board receiver kit that provides
single-band
coverage with each kit. The board size is 1.5 inches square and a height of
about 0.6 inches.   Connections on the board provide for QSD mute so the
SoftRock can be used with a separate transmitter.

A view of the of the earlier v6.0 SoftRock may be seen at

which gives a good idea of the general look of the SoftRock Lite board
except the Lite is a square board.

The software may be download at no cost with a number of programs available
that will play the SoftRock receiver.  Please see:

Documentation to build the kit may be downloaded from files area of

the website to download the documents for the kit.
