Version 5 SoftRock, anyone?

kb9yig
 

Hello Everyone,

I am working on a version 5.0 of the SoftRock receiver and want to
see if there is interest enough to do a kit. The version 5.0
SoftRock oscillator will be at the fundamental frequency and depend
on 90 degree phase shift network to generate the quadrature clocks
for the QSD. This should give more flexibility in finding suitable
crystals for various bands.

The version 5.0 will consist of a two board stack with each board
having dimensions about 1 inch by 1.5 inches. The bottom board of
the stack with have a 5 VDC regulator, two voltage comparitors, the
QSD circuit and the low noise audio amplifiers. The upper board
will contain the oscillator circuit, the 90 degree phase shift
network, and the BPF for the desired band. The two boards will be
joined electrically by a row of header pins on the top board and the
corresponding sockets on the lower board. A threaded standoff
between the two boards will provide for mechanically holding the
upper board to the lower board. Corner mounting holes will be
provided on the lower board.

External electrical connections to the lower board will include,
supply voltage (9-12 VDC), an antenna input and a stereo audio cable
for line-in connection to the PC.

Target kit price is in the mid-twenty dollar range for one set of
boards and components for a single band. Additional band kits might
be on the order of $12 each with 80 meters through 30 meters and
possibly 20 meters also covered.

Please let me know if there would be any interest in such a kit.

Thanks and 73,

Will it be able to be driven with an external oscillator? How many thousand
kits will there be in the first batch?
73/72 - Mike WA8BXN

Yes, that would be one of the considerations to make it easier to drive the QSD from an external quadrature clock.

Thousands, I was thinking more like doing a prototype run of twenty-five.

sign me up for at least one. it would be nice to make the layout easily
accomodate something other than the usb power approach as well.

No money now for sure!? I am thinking I could have a limited number of kits ready by the first week of November.?
?
Incidently, I am considering the possibility of including an option for a third board in the stack that would be a QSE, quadrature sampling exciter.? This would open up generation of CW, SSB, and digital transmission modes.

Tony and all.......

YES, please do...especially the third board! W1TAG has already designed a LF exciter using a slower analog switch, and it works well at 137 and 190 Khz.

I have severe reservations about the practicality of cw transmissions generated by a computer. The top of the line SDR-1000 has dreadfully annoying and nearly intolerable delays associated with software when operating CW. I would have bought one of those I think, if it wasn't for this problem.

I'd buy it and use it though, it would be an awesome little rig! Had no idea you were doing further development Tony. Was going to ask you whether you need someone to collect parts and put the kits together and sell them....but it sounds like you have the situation well under control.

After your prototype is beta tested, I hope you will be prepared for the tremendous response you will have....plan on a run of 1000 though, especially if you are doing the companion low power exciter!

Regards,

Art
 

Hi Tony
Count me in for the Two Board Unit.

Might need an Mute Circuit and Antenna Relay!

Here we go again, another 1000 kits!

Hi Tony,

I am interested in the newer version.

I am not sure whether you have knowledge of the shipping process of the 1st one.
The shipping started Sept 29 and I am on the list. Are they shipped in batches and is it
still on going?

Hi Tony,

Yes I would like one as well.

One thought came up today at work... is the image nulling setting dependent
on the softrock used or can I use any softrock once I get it nulled? I
didn't know when I get my other softrock built if I need to go through the
nulling or not or if it is once per soundcard.

Hi Chris,

As I go through test on the SoftRocks I am building for people, I find image null from unit to unit is fairly uniform. It does take a little adjustment each time to get the best image rejection as I go from one unit to the next. Changing soundcards would probably require a change in the image null adjustment. What I typically see using a mother board soundcard in my PC is a phase slider setting around -100 and a gain slider setting near zero to null the image. I wonder how that compares to what others are seeing?

The SDR-1000 includes an impulse generator circuit on the RFE board. PowerSDR software changes in the future will include an automatic image null feature. This could be done on a receiver as simple as the SoftRock also.

joined electrically by a row of header pins on the top board and the
corresponding sockets on the lower board. A threaded standoff
between the two boards will provide for mechanically holding the
upper board to the lower board. Corner mounting holes will be
provided on the lower board.

External electrical connections to the lower board will include,
supply voltage (9-12 VDC), an antenna input and a stereo audio cable
for line-in connection to the PC.

Target kit price is in the mid-twenty dollar range for one set of
boards and components for a single band. Additional band kits might
be on the order of $12 each with 80 meters through 30 meters and
possibly 20 meters also covered.

Please let me know if there would be any interest in such a kit.

Thanks and 73,
Tony KB9YIG

Hello Everyone,

I am working on a version 5.0 of the SoftRock receiver and want to
see if there is interest enough to do a kit.? The version 5.0
SoftRock oscillator will be at the fundamental frequency and depend
on 90 degree phase shift network to generate the quadrature clocks
for the QSD.? This should give more flexibility in finding suitable
crystals for various bands.

The version 5.0 will consist of a two board stack with each board
having dimensions? about 1 inch by 1.5 inches.? The bottom board of
the stack with have a 5 VDC regulator, two voltage comparitors, the
QSD circuit and the low noise audio amplifiers.? The upper board
will contain the oscillator circuit, the 90 degree phase shift
network, and the BPF for the desired band.? The two boards will be
joined electrically by a row of header pins on the top board and the
corresponding sockets on the lower board.? A threaded standoff
between the two boards will provide for mechanically holding the
upper board to the lower board.? Corner mounting holes will be
provided on the lower board.

External electrical connections to the lower board will include,
supply voltage (9-12 VDC), an antenna input and a stereo audio cable
for line-in connection to the PC.

Target kit price is in the mid-twenty dollar range for one set of
boards and components for a single band.? Additional band kits might
be on the order of $12 each with 80 meters through 30 meters and
possibly 20 meters also covered.

Please let me know if there would be any interest in such a kit.

??? That would be super, Tony!! I WILL be buying that option WHEN you make it available. It would be neat to have the first SDR Xcvr in an Altoids tin.

No money now for sure!? I am thinking I could have a limited number of kits ready by the first week of November.?
?
Incidently, I am considering the possibility of including an option for a third board in the stack that would be a QSE, quadrature sampling exciter.? This would open up generation of CW, SSB, and digital transmission modes.
