I was lucky. There was an extension computing center in the basement of my dorm at Case (not CWRU then) in '67 with keypunches, and a window with a reader and a printer maned by a bored student. I

I agree some of the scores seem unlikely and there have been a few comments about the system being too complicated (for those not used to contest scoring) and how theoretically if you work 100

It certainly appears that some scores are not correct.? If you are using the N1MM+ custom template I provided above, ( Mar 26) you need to leave the last col QCX) blank if the other station was *NOT*

I looked at the scores on 3860 and to me it looks that something is not ok with the mulitpliers K0PD 32 QSOs and 32 Multipliers wouldn't that mean he ahd QSO's with 32 QCX users ? Also some others if

I made an RD06HHF external amp, for my QRP Labs rigs and for general use. https://sites.google.com/site/andyg0ftd/5w-qrp-amp I have one of my QRP Labs rigs set for about 200mw output, and pass it via

Hi Michael, Thanks for your post on this. I understand how to replace the standard transistors with the Mitsubishi device. But how did you configure the extra bias pot? Did you simple replace this, or

I recently had a QCX to look at and T1 had already been removed to rewind and wasnt likely to survive another removal/ replacement sequence ( well the pcb wasnt going to survive) So although you cab

While the upper hf bands are not particularly stellar, I'm using the QCX-17, largely, on the 30m band. Just worked Marty, K1FQL in Florida on 10101.7 kHz, while running 4 watts from the QCX-17, with

If you have access to a 3D printer, you can try to make this small and lightweight key and see if you like it. The design can be downloaded from Thingiverse

I have started to do some more precise frequency measurements using the Progrock and the QLG1 with "inverted logic" PPS output, with a 1kilohm resistor in the PPS line between the two boards (at the

Hi Dan It wasn't YouTubed last year, but the audio was recorded for a podcast. http://qrp-labs.com/dayton2018.html has the slides and the link to the audio. Same procedure this year. 73 Hans G0UPL

But you managed to avoid TECO. John F5VLF

Does anybody know if Hans' presentation will be captured in any way? I'd love to go to FDIM just can't swing it. I will go to Dayton this year. I know one of Hans' presentations last year was

Thank you Hand for preserving a very cool bit of history so comprehensively on your website. Chaz Fletcher G3DXZ also had a minimalist 1 chip stabilizer I thought was very clever and looks pretty easy

Hi Steve Yeah, happy days. By the way, the URL is http://hanssummers.com/z80.html - but because the site has an old version of Joomla content management system, there seems to be some issue, sometimes

Hi guys, I’m waiting for Hans to complete the design of the QRP Labs computer. But wait. He’s already done it http://150.ip-149-56-110.net/z80.html Have fun! Steve G0XAR

Hi all Huff & Puff was a passion of mine. I was licensed in 1994, but for various personal reasons did not go on air. I did keep reading RadCom (monthly journal of the RSGB) and was fascinated by the
