Re: V5.0 SoftRock design (volunteer for alpha testing)

Bruce Beford
 

Hi, Tony.

Sounds real good. Put me on the list as an alpha test volunteer.
Would be willing to evaluate each board as it becomes available.
(i.e. main Rx board, plus each band/filter board, plus TX when
available.)

Good Morning All,

There has been good response to doing a version 5.0 SoftRock so I
started the board layout this morning.

The board size of 1 inch by 1.5 inches for the top and bottom
boards
looks like a good fit for what needs to go on each board. The
bottom
board will have the four corner mounting holes with the holes
sized
for #4 hardware. A 10-pin connector will be located along one of
the 1.5 inch sides of the bottom board to mate to a corresponding
row of pins on the top board. Pins on the top board will be
double
ended to pass power/ground and various signals up to a possible
third board for future use. (Future use could include a transmit
function.)

A receiver mute connection will be provided on the bottom board
and
require a logic low signal to mute the receiver.

Schematic and board layout will be done in the ExpressPCB
software.
The ExpressPCB software is free to download from the internet and
as
I get the design entered I will post the files for others to exam.
I hope to have the design files in pretty good shape by the end of
this week.

If the design looks like it will fly, I want to get boards and
other
parts on order the week of October 17 so that kits can go out to
alpha testers the first week of November. Fifty kits in the alpha
run looks possible with kit price in the mid-twenty dollar range.

Your inputs would be appreciated.

??? Sounds great Tony. I don't think I would make a good beta tester. I am not that proficient at electronics. I do well at putting the kits together, but some/most of the "what makes it tick" part escapes me at this point.

Subject: Power SDR going deaf?

I initially started using the soft rock with the Power SDR software
but last night downloaded the SDRadio and am hearing a lot more
signals with it. I was able to easily null the image in the Power SDR
setup and when there are a lot of siganls I don't notice anything
except that it sounds real nice.

So, I was wondering if anyone else has done and A/B with the 2 pieces
of software and were able to tell a difference?

Re: Version 5 SoftRock, anyone?

Good Morning Edson,

Yes, we did get a chance to test the SoftRock with the PCM2900 chip and did a alpha run of kits that included the PCM chip. The receiver works fairly well with this chip and Bill, KD5TFD, was able to fix the sample time-offset problem in software. I like how well the little receiver plays with even a mother board soundcard so I am not sure if I will do anything else with the PCM2900.

Thanks for the info on the second USB "soundcard" chip.

Hi Tony,

The modular approach for the new kit sounds really nice.

Did you have a chance to test the PCM2900 with the SoftRock? Perhaps
another little board with a PCM2900 could be added to the kit. This
way, people could just connect the SoftRock v5 to the computer and use
the internal computer/laptop soundcard only for listening and mic
input. This would be helpful specially in a transceiver configuration.
Another advantage would be the elimination of soundcard adjustments,
extra cables, etc. Adjustments could be done only once since the
soundcard would be part of the receiver.

There is another chip that could be used instead of the PCM29xx, the
UAC355x from Micronas. This chip is a little more complex to use, but
does not have the sample delay problem like the PCM2900. The chip is
currently used in the iMic USB audio interface.

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.

Softrock on 60 Meters

Bob Hillard
 

I found a 83 cent crystal at Mouser that will put the SR40 on 60
meters. (Digi-Key also has this frequency xtal). It's a 21.4772 mHz
xtal, resulting in an oscillator frequency of 5.3693 mHz. The Mouser
part number is 695-HC49US-214.

This is not the ideal oscillator frequency for this application, but
it does give you three of the five 60m channels; 2, 3, & 4.
Unfortunately channel 3 has the oscillator sitting in the middle of
it, so it's not very useable. However channels 2 and 4 work, and
channel 4 is probably the most active 60M channel.

A 21.562 xtal would be a better (but more expensive) choice; resulting
in an oscillator frequency of 5.3905, which would reside in the 29 kHz
gap between channel 4 and channel 5. This crystal would give you
channels 3, 4, and 5 (channels 4 and 5 are probably the most active).

The SR40 on 60M (or is it a SR60 once converted?) works great. No need
to change the band pass filter either.

Re: XG-1 and XG-2

Well, that's kind of what I decided esp. since I
already had an XG1. hi. I agree that the frequency is
not that important. I actually use my PIC-EL with DDS
card more for things like testing the SR-40 than I do
the XG1, but once in awhile the accurate output is a
plus.

Eric,

I'd looked at the two schematics and decided that
the XG-2 wasn't worth 20
bucks more. The series capacitors are used to trim
the crystal frequency
similar to what I'd done in Rock-Mites. I'm not too
concerned about
frequency accuracy but do want signal level
accuracy.

I sent a message to Elecraft to confirm what you
already knew and what I
had thought about using pretty much any crystal.

On the Accuprobe thing, didn't seem to practical to
me to have an RF probe
that big. I've used one in my field strength meter
and another one is
partly modified to use with my NoGaWatt directional
coupler. Need to get
that done -- it will be a WM-2 work-a-like. I have
one more to use with
what ever project Chuck Adams was doing. Haven't
heard from him on that
one lately. My RF probes, non powered, will fit
inside a 22 magnum
