Hi Bob, Yes, I mail a built/tested unit to you several days ago. 73, Tony KB9YIG

Tony I sent you email the other day for a sr40.I am not sure if you sent it out or not.I usually get a message from you when you send out your mail.I havent heard from you and thought I would

FS v4.0 SoftRock40 receiver
Good Afternoon All, As I continue to build SoftRock40 kits for various hams I now have ten extra built/tested v4.0 SoftRock40 receivers for sale at $38 each. This price includes mailing cost to

SR-40 changes for Kenwood IF 8.830MHz
I ordered a pair of crystals at three different frequencies close to the Kenwood IF. One set on the high side, two sets on the low side, inductors, and trimmer capacitors to see which one is the

Re: SSB demod, was Re: carrirer oscillator
Thanks Frank. That's quite clear. Is it correct to assume that "if there is no sound card, and if we have a higher sampling rate ADC, we can see more portion of the band"? Or rephrasing it this way -

Re: SSB demod, was Re: carrirer oscillator
But on the SR-40 the oscillator is fixed! if you want to listen to 7.058 you have 2KHz audio coming out, the only thing you can do is change the crystal (good luck) or use a DDS instead of the built

Re: Not working: HELP
Stan, You might also want to check for cold solder joints in the oscillator circuit. I had the same symptoms and found a cold solder joint on the ground end of the 2.2K resistor off the emitter of Q2

Re: SSB demod, was Re: carrirer oscillator
Agree. Why I talked about software is that the only way I can conclude the center frequency is 11.025khz is by looking at what the software is trying to do. I do not yet have SR40 hardware beside me

Re: Computer and Sound Card
The SantaCruz will be a fine card for the SoftRock. The software will surely work with it as it was the original card recommended by Flex-Radio with the SDR 1000. The reason you're seeing a lot of

The other part of the equation is the computer and sound card. What is recommended ? I know that previous SDR discussion revolved around some of the better Creative Labs sound cards and at one time

Finally got it. NICE RECEIVER!! Went through touching up pins on the IC's and the filter again. Hooked it up and VOILA !! Stan Rife W5EWA Houston, TX K2 S/N 4216
