Good morning. I've just completed the assemble and some initial testing of the SoftRock40. The green led lights up and the Fixed HW Osc @ 7.056MHz can be seen and heard. That's about all that works since the SoftRock40 does not appear to be receiving any signals from the antenna. There are two issues/questions follow: ISSUE#1: Under "Configure & Use", step#4 is not clear. It says " With the oscillator running, tune to the frequency that is as much above 7.056 MHz as the test oscillator is set below 7.056 MHz." I'm not sure what this means! Does this mean that an external signal generator should be connected and tuned to (7.056MHz -n), while the SoftRock is set to (7.056MHz +n)??? Please explain. ISSUE#2: I'm not able to null any images under "images" as described in step#4. (In fact I do not see an image, only the 7.056MHz test signal.) Any assistance would be greatly appreciated. I'm stuck. Thanks & (((73))), Jim WA2UMP

SR-40ers, PA contest this morning provided lots of signals to check out. Also a RTTY thing early this morning. Had several things running like email and such and some strong signals sounded rather choppy. I minimized the PowerSDR window to do something in email and the signal cleared up -- no longer choppy. OK if you just wanted to listen to the one signal but not too useful for tuning around...[g] Better to close all the other applications and open windows of course but interesting anyway -- maybe.

Bill, I found it (Display Tab, Setup Book) and set it down from 15 to 6. That made a big difference. I see a message from Cecil that suggests several other options for reducing the CPU busy time. I'll mess around with things and see what seems to work best for this laptop (. Thanks! Still having fun with SR-40...

Bruce and All, I had installed DIP pins for the crystal and the two capacitors to facilitate the band change.

Took a little work and troubleshooting, but it feels like a whole new world just opened up... Wow! Ed AA1WZ

Bruce and All, Just did the minor mods needed to change bands and all is working FB. Signals are fair this time of day from about -135 to -100 dBm on some sigs. I didn't have 33pF caps for C6 and C7 so I used 39pF np0/c0g instead. Will be looking to see what the panadapter looks like when there is a DX pileup happening...[g] Chuck Carpenter, W5USJ, Point, TX -|- Rains Co. -|- EM22cv -|- 72 es 73 50 years -|- 19 - K2OFN and 31 - W5USJ -|- Most fun = QRP since 1984. www.w5usj.com hosted by Hamnutz.com -|- NeTxQRP www.netxqrp.com

After 3 long days of waiting for my softrock to arrive, it finally did! Now I won't be waiting at the mailbox to meet the mailman! Took me much longer than 3 hours to build, but I made some errors that had to be corrected:>: For anyone about to go through this, I suggest the following: Don't do like I did....and put the tanatlum caps in backwards! Even with a lighted magnifying lamp, I didn't see the little X on the component indicating the polarity. Had to remove 3 of them and reinstall them, fortunately I caught this before I applied power. Software install went without a problem. I'm a little concerned that I didn't get prompted to install some other utility programs like the directions said I would....but it fired up without errors on the first try. The moment of truth came.......time to plug it in and look for smoke. No smoke, but the LED is very dim....oooopppssss, must be a problem. Turns out that's not a problem, they are all pretty dim,! The 2.2 K series resistor limits the LED current to 1.3 ma. No doubt, this was intentional due to the nature of the beast in that it draws power from the USB port. My Dell laptop has no stereo input on the sound card and my antenna was a 6 foot clip lead laying on the bench. So, I haven't adjusted the null for the opposite sideband yet. Even with the bad antenna, I heard a few signals, enough to know it works! Most of the signals I heard were noise coming from the computer though, but I dido manage to hear some CW. My computer is 59, much louder than the few signals I was able to hear with the limited antenna. So, it looks real good so far. At some point, my softrock will probably be installed in a box! So I attached both cables to the same side of the PCB, leaving one mounting hole available for the day when I want to install it in a box (both cables anchored to the same mounting hole). Took me awhile to figure out how to adjust the frequency on the flexradio software.....but that was the hardest part of the software aspect of the testing. Fired it up with SDRadio, it works with SDRadio software too. I have a problem with occasional (very brief) dropout of the audio every 3 to 4 seconds for 100 msec's or so. It also pops when the audio drops out. It does this whether the softrock is plugged in or not though. Tried setting the soundcard to use mime instead of the windoze driver, but had the same results. I can make a recording of it (I think). Will probably have time to work on it tonight after the house gets quiet. So far so good. Hope everyone's assembly goes as well as mine. Regards, Art

Hi to ALL Just arriving: I would like to get one kit too :-) Who can help, telling me what to do? YOUR suggestions are HIGHLY ***appreciated*** Many thanks in advance for ALL your support! 73 de Jose Silva CT1AXG

If you have a PC that is a tad slow for the Powerflex software or your running Windows 98 or ME, try the link below. < http://digilander.libero.it/i2phd/sdradio/index.html > The latest version of the software is Ver .95 The software is not as advanced as the Powerflex software but it will let you try out your SR-40 and see what all the raucous is about. There is no CW mode, but you can receive it in SSB mode, the filters are adjustable can be made quite narrow. It has some nice features such as the fact that the Panoramic Display can be 3KHz, 6KHz, 12KHz, 24KHz, or 48KHz, the noise filter works quite well also, and it's very simple the setup. Enjoy Cecil Bayona KD5NWA www.qrpradio.com I fail to see why doing the same thing over and over and getting the same results every time is insanity: I've almost proved it isn't; only a few more tests now and I'm sure results will differ this time ...

SR-40 Folks, Something I should have done first rather than stumble around and ask a lot of questions. There are two PDF files on the Flex Radio Systems download page. These are quick start and complete SDR-1000 operating manuals. http://www.flex-radio.com/ Some folks most likely did this first and were most helpful. But it did make it easire to understand the manuals...[g] Chuck Carpenter, W5USJ, Point, TX -|- Rains Co. -|- EM22cv -|- 72 es 73 50 years -|- 19 - K2OFN and 31 - W5USJ -|- Most fun = QRP since 1984. www.w5usj.com hosted by Hamnutz.com -|- NeTxQRP www.netxqrp.com

SR-40 Folks, Tony mentioned this to me. Hadn't seen it mentioined here on the lists so I'm passing it along for Tony...[g] Use W1AW as a signal source. Note any difference in frequency when you zero beat the signal in the filter passband. Then go to the Setup Book, SR-40 tab and adjust the frequency there accordingly. Tony sez you can get really close this way -- W1AW frequency at 47.5 is pretty accurate.

Below is a link to a company that I bought from to build up my parts stock. They have a lot of SMT parts kits for a reasonable price. They also have project kits with lot's of extra parts so you can experiment making changes. < http://www.vakits.com/ > No fiduciary interest, just though to pass on a source of SMT parts.

I completed my SoftRock-40 just before leaving for the GQRP mini-convention in Rotherham, and didn't have time to test it. I've just plugged it into my PC (running the SDRadio software) and connected it up to my trusty Marconi 2019A signal generator and it seems to be working OK - I can hear a -106 dBm signal at 7.040 MHz and can probably go lower. Has anyone else checked the sensitivity? I'll try it out with an antenna later. I've promised George, G3RJV, a write-up for Sprat. I met someone at Rochdale who is building one, and someone else who wanted one but missed out. 73, Leon -- Leon Heller, G1HSM leon.heller@... http://www.geocities.com/leon_heller --- [This E-mail has been scanned for viruses but it is your responsibility to maintain up to date anti virus software on the device that you are currently using to read this email. ]

When I click on the Power SDR icon on the Desktop, the SDR dialog box comes up and it has "Softrock 40 Edition". The loading bar moves from left to right. At about the halfway point of loading,another dialog box comes over the top of the SDR dialog box "unhandled exception". The loading stops. I have tried deleting the SDR programs and .NET Framework, and downloading again, and reinstalling them. No change - still "unhandled exception". Computer is 3.2 Ghz with 1Gb memory running win XP Home Edition. Any suggestions? My SoftRock-40 card is working on the bench. Bob Bartel

Hi All, Completed my SoftRock40 this afternoon. Took about 3 hours. I'm using the external power mod (78L05 in place of 2N3904, etc.).Current drain on a 9V battery is 29+ mA. My PC is a 1GHz Dell Optiplex GX200 with sound on the motherboard. Signals came through upon first powerup. I don't have an XG-1 to perform the image null. (Will borrow one tomorrow). I was able to make a null adjustment while listening to a fairly strong CW signal. Both gain and phase are very close to the middle of the range for a fairly good null. I don't expect much change when I use the XG-1 tomorrow. On to some on-air listening-- 73, Milt W8NUE Austin, TX -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

guys Im finally geting time to start my kit AND Ive ran into a problem. Im installing the crystal but Im finding the ground hole for the case ground isnt thru the board.There isnt any solder in it its like it hasnt been drilled.is this correct? Steve KG4JNL

Had to jump in and say my SoftRock40 is working super too. What a hot receiver! Finished the kit Sunday night, found the bad solder joint after coming home from work this Monday night. Har It sure sounded sweet when I heard signals for the first time. This is one amazing little receiver! I have been tuning around all evening copying CW on a busy 40 meters and looking for the weakest signals up next to strong signals. This SDR does work. This receiver is better than my Elecraft K1 by far. I hope there will be a way to expand the band receive range in the future. Thanks to all involved in making this kit available at such a reasonale price. 73 John N3WT

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.

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. Bob WA6UFQ

Hi, YES please. Count me in, I'll order one of these kits. Jarmo Blomster oh8kva
