| 2025-01-05 12:38:52 | DJ3CE@social.darc.de | 1 | Success! | As I (finally) did my QSL card in October already, I chose to implement minor improvements and to do some design work for friends. Harder-than-thought to do something different if there's a basis, but GIMP and Inkscape have proven to be very capable tools – still learning :). Let's have a QSO so I can send you my card :).

| 2025-01-11 17:55:40 | DJ3CE@social.darc.de | 2 | Progress update... | Sometimes OH2B is audible on 20m. On all other bands my miniWhip picks up too much QRM happily…At DL0DPM, MfK Frankfurt (museum of communication), we have a printed world-map with leds lighting up for the 20m IBP-Beacons – quite often that's the eye-catcher for visitors and a good start for talking about propagation. Listening to beacons while a led shows the signals source sometimes is the moment people realize what we mean with "propagation" :). HC02 #hamchallenge |
| 2025-01-26 21:59:52 | DJ3CE@social.darc.de | 4 | Success! | HC04S For my first callsign, DO5GC, I can find no evidence it had been assigned previously. My current callsign DJ3CE had been assigned to one of the founders of DOK P05. Some traces can be found until 1995. I got the callsign in 2022. #hamchallenge |

| 2025-02-08 20:03:24 | DJ3CE@social.darc.de | 6 | Success! | This weekend hosts (one of) my favourite contests, the PACC (thanks @PA3DSB for the note!). It was one of the very first contests I took part in – and as dutch operators give a constant exchange it had been a very good start into contesting :). I managed to fit in a bit of participation today, after taking part in a more "local" contest. So I guess: HC06S #hamchallenge @hamchallenge |
| 2025-02-08 20:12:26 | DJ3CE@social.darc.de | 5 | Progress update... | … oh and I did some work on the QRZ/HamQTH pages of my callsign – but work in progress, I'm still missing a good profile picture… 🙃 (… more ham related than my profile picture here… 🤭 ) HC05 #hamchallenge @hamchallenge |
| 2025-03-12 22:34:22 | DJ3CE@social.darc.de | 11 | Success! | Thanks @mischk, your #hamchallenge report motivated me to do a NOAA sat agn (and get s.th. ready for decoding agn).Doppler-shift never fails to draw beautiful waterfall graphs :). But regarding the received image there's a long way to go until I get anywhere near my personal NOAA-reference @M0PWX ;).Setup: Ant 2m-groundplane located behind a window, gqrx & gpredict (big thanks, Alexandru Csete!) and aptdec.That's kind-of HC11S … still trying to catch up with other weeks. |

| 2025-03-29 14:54:54 | DJ3CE@social.darc.de | 9 | Success! | There is a 10m/70cm linked repeater on a nearby mountain, which is (nearly) los to my qth, so I usually use the 2m or 70cm repeaters there. Today I had two qsos via the 10m/70cm linked repeater, one with me using 10m and one where I used the 70cm part. Well, I guess it's my (compromised) 10m-setup, but 10m did not work as neatly as 70cm. Still: HC09S I guess :).#hamchallenge @hamchallengep.s. Edit, yeah, numbers confused... sri :(. |
| 2025-04-05 10:01:25 | DJ3CE@social.darc.de | 14 | Success! | As I recently kind-of-partly messed up my log a bit (part of improving #wavelog, you may find the pr, fixed before merge ;)) I know about my log-backup quite well: There are nightly MariaDB dumps, which are part of a (deduplicated, versioned, compressed, encrypted) 'default' backup strategy of the server. The resulting backup archive has a 'sporadic' manual rotating offsite offline copy (read harddisks). Weak points: encryption key and software. #HC14S |
| 2025-04-21 12:19:25 | DJ3CE@social.darc.de | 16 | Success! | Trying to get back into order with the #hamchallenge s. Made two QRP #cw SOTA contacts on 40m yesterday from an improvised shack (QMX, EFHW). They (on a summit) knew my name, i knew nothing. The ‘P’ in my callsign means ‘polite’ and ‘prepared’ 🙈. HC16S |
| 2025-04-23 22:38:03 | DJ3CE@social.darc.de | 17 | Success! | For #hamchallenge HC17S I relied on data from https://repeatermap.de (Thanks to DK3ML for this resource!). While the nearest FM repeaters are well known (1.3km for 70cm, 16km for 2m), I got some interesting other nearest ones, depending on mode and band. For ATV on 70cm the nearest one seems to be about 440km away (DB0BC), while the nearest 2m DMR repeater seems to be just about 90km away... @hamchallenge |
| 2025-05-08 15:26:05 | DJ3CE@social.darc.de | 18 | Success! | #hamchallenge HC18S took place last Saturday from a mountain with a nice lookout tower in southern germany (Hohloh, Schwarzwald) via DMR/Brandmeister with an Anytone, which was my first radio. I used a 70cm-Repeater 160km to the north and had two nice QSOs. It never fails to amaze me how far 70cm works if LOS is given. @hamchallenge |
| 2025-05-21 22:12:07 | DJ3CE@social.darc.de | 21 | Success! | Last year, I had thought about decoding DCF77 with gnuradio and failed quite miserably. So this weeks #hamchallenge was a good chance try this again. I'd never try to really implement it like this in some sort of 'product', but, I get a stream of bits out of it and with some manual bit counting, I can tell you, that there won't be a leap second in the next hour ;). HC21SAttached there's a screenshot of the flowgraph and some real-signal graphs.@hamchallenge |
| 2025-05-29 12:14:42 | DJ3CE@social.darc.de | 22 | Progress update... | Using qucs-s and ngspice for #hamchallenge HC22. I'm still hunting "issues" with (i guess) numerical instabilities, leading to near constant simulations (transient simulations of quite simple transistor circuits). Sometimes a simulation works well and with just changing back and forth a component, stops working. 🤔 @hamchallenge |
