RXTX+Xtall v6.3 transceiver
- Hi Gert,The kits now available are listed below:SoftRock Lite receiver kit information is given below. Also now there is
the v9.0 Lite+USB Xtall receiver kit and one watt RXTXv6.3 SDR
transceiver kit. Band coverage from each center frequency 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 v9.0 Lite+USB Xtall kit provides an all HF coverage receiver where
center frequencies are set via a USB connection to the v9.0 circuit board.
The v9.0 receiver has MDS of at least -118 dBm on each of the amateur
bands and covers the range from 1.8 MHz to 30 MHz with four plug in
BPF moducles supplied in the kit. The v9.0 Lite+USB Xtall kit is priced
at $44 for US/Canada and $45 for DX where each kit price includes
postage cost.The RXTXv6.3 board includes a Lite+Xtall receiver function along
with the RXTX transmit function. A four-position DIP switch at the
edge of the circuit board provides for setting sixteen possible
center frequencies for receive and transmit functions. The
Lite+Xtall BPFs are used with the receiver function for band changing
and a PA/Filter module plugs on top of the RXTX board for changing
the transmit band. As with receive, four PA/Filter modules will be
required to cover all HF ham bands. Also included on the RXTX board
is the Rocky 3.x serial interface function for control of the PTT
input to the board and to provide paddles input to the Rocky SDR
program.The RXTX+Xtall v6.3 kit price is $50 for the RXTX
board kit along with the receiver BPF kits for all HF ham bands. The
$50 price would include the CMOS Si670 device used on the board.
(Without the Si570 included in the kit, the kit price would be $35.
The RXTXv6.3 board also provides for use of the LVDS Si570 part.)
Each PA/Filter kit would be an additional $15 per kit. Thus for two
or three band coverage the RXTX+Xtall v6.3 kit group would cost
$65. Additional PA/Filter modules would expand the band coverage
such that all HF bands could be covered at a total kit price of $110
The DX price for the RXTX+Xtall v6.3 kit is $52 and each PA/Filter
kit pirce is $16. In each case the kit price includes mailing cost.
PA/Filter kits are for band groups: 160m, 80m/40m, 30m/20m/17m,
and 15m/12m/10m.Now available is the USB I2C interface kit at $10 for US/Canada and $11 for
DX. The USB I2C interface kit provides a means of setting the Si570 device
on a v6.3 RXTX+Xtall transceiver desired frequency from a USB port.
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 atwhich 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:Flex Software

I pulled out my old Softrock RX V 6.0 for a demo in a school and
noted that there a new developments in hard- and software.
Is currently a TRX kit available? What are the costs?
