Hi Clint, Not sure if this is relevant or not, but I am still in the process of finishing off my board and noted a timing issue when running WSPR with the clock free running (v1.5 firmware). I have

Hi Hans, Thanks for the thoughtful reply! I'll disable the GPS mode and look to see if the clock accuracy works as it should when free-running: I've not tried that and in retrospect, it would have

Hi Clint There's a lot of information there, I have some things to comment/suggest etc. Firstly, I think it would be wise to check that the clock divide-by-8 fuse problem isn't applicable to your

That's good to know. I was trying very hard to think of something that I'd done wrong and I just couldn't think of anything. I still have a small problem with the unit being a bit funny about

I've had a few minutes to stare intently at the display and I have made a few observations. First of all, here's what I've done to rule other things out: - I was able to issue commands to the GPS

Interesting about the re-application of power to get the unit to start- I recently had a PIC based project that had the same start up problem and I discovered that I had to switch from a regular 7805

I've put my 30 meter UQRSS together and have been fiddling with it for a bit now and have noticed something that has me scratching my head. I'm using a Axiom Sandpiper II GPS module that has a serial

Hi Stefan Just to confirm what others have already said - there is no change in the processor at all, they are all identical for any frequency from 0.5MHz to 20MHz. You must enter the correct

Hi Alex, There have been a number of firmware versions since v1.02, the full list is here http://www.hanssummers.com/qrsskitmm#Versions , but I do not think that any of the bug fixes are applicable

GQRP club have the 7040Khz crystal too... Also,the 3500 and 7000Khz crystals from AM Tools are the ones that will pull further and are ideal for the UQRSS kit on 40/80 QRSS. They are the larger can

Amtools on eBay also stock 7040 kHz. Also found

Hello Philip, many thank's for your info. Sometimes it is better to ask first. So I will build it up for 40 m and therefore ordered a quartz with 7,040 MHz for 40m-WSPR-band

Stefan I have a kit with sockets for the capactitors and crystal and I use external LP filters to suit each band.. The same board works on 20/30/40 and 80 so yes, you're good to go.. Philip

Thanks lads for the replies. I think that's where some confusion has arisen, because the G0PKT/ Martello website mentions using one of the kits for the G0PKT 24/7 beacon. Obviously I've been trying

Dear Hans and dear Stephen, I have here 2 kits of 30m-UQRSS. The first one I have built up, working well. Now I think about building up the second one not for 30m but for 40m. The question is: Is

Stefan & Steinar, It's working again << BIG SMILE >> I replaced the 74HC00 with a 74HCT00 (note the "T") and the transistors are staying much cooler. I couldn't get a 74HC00 over the weekend so I

Hi Andy I'm not sure exactly what G0PKT is doing. Not everyone is using the "Ultimate" kit of course ;-) So he may be using something else. In the Ultimate kit is is possible to program your own

Hi Andy, I guess you mean by the "drawing modes" the Triangles and SlantCW and FATCW these are generated by Chris DL6JAN's CWKTiny keyer. G0PKT and others use this with the first QRPLabs kit instead

Andy, Please take a look at the manual which you can download from www.hanssummers.com. It should explain pretty much everything you need to know. 73s Steve

Thanks for the quick response Hans, hope this helps better diagnose if there is a problem The software version is 1.02 Kit bought in August Receiver is connected to PC running Argo Mode selected
