Some time ago I saw announcements of an igate build project from PI4RAZ, the amateur radio club in Zoetermeer. An igate is a system that receives APRS messages and forwards them to the Internet aprs servers. There is a distinct lack of APRS coverage here in Utrecht, so more places that receive those messages and pass them to the Internet are a good idea. A specialized repeater to repeat them on the air would be even better, but that needs a special radio license which is one step too far and expensive at the moment for me. The electronics came in months ago, but time to pick up the soldering iron and start with the hard part wasn't available. I started this monday with that hard part: soldering a VHF module on top using something close to surface mounting. Just with a lot more space between the soldering islands than real surface mount. Still needed good light and a magnifying glass to check my work constantly. I only had to desolder one small blob of solder which went in the wrong direction. After that I soldered the resistors. That went fine. After that my eyes were too tired, but the first step has been made.
As I mentioned before I have some future cycling goals which include some form of long-distance cycling journey, with serious influences from the book Computing Across America. Naturally amateur radio will play a part in such a cycling journey, just as Steven K. Roberts had on his trips. Via the german amateur radio club DARC I found this bit in the "Deutschland-Rundspruch 24/2020":DK3JB erreicht erstes Ziel auf seiner Funk-Fahrrad-Reise Hans-Gerhard Maiwald, DK3JB, hat nach mühsamer und beschwerlicher Fahrt, teilweise auch wegen schlechter Radwege, am 15. Juni gegen 21 Uhr sein erstes Ziel, Kappel im Hochschwarzwald, erreicht. Dabei legte er ohne E-Unterstützung 580 km mit seinem 40 kg schweren Radanhänger zurück. Dem 72-jährigen OM geht es gesundheitlich gut. Hans-Gerhard gelang es, den weitaus größten Teil der Strecke permanent mit seinem TH-D74 in APRS aufzuzeichnen. Dabei hat sich der 1200 g schwere 12 V/20-Ah-Lithium-Ionen-Akku sehr bewährt. DK3JB hat zahlreiche Verbindungen in FM und D-Star vom Fahrrad aus getätigt. Durch Ludwigshafen wurde er von mehreren Funkamateuren gelotst und seine Route mitverfolgt. Hans-Gerhard bleibt bis Sonntag in Kappel und radelt danach vorerst an den Bodensee weiter.And I found out more about the cycling tours between Siegen and Friedrichshafen in Germany via Funk-Fahrradtouren of DK3JB and it is very inspiring to me. There is also an article DK3JB wieder mit dem Fahrrad unterwegs nach Friedrichshafen - funkamateur.de with information about this tour in 2020 (all in German, which I can read but not really write). He has done this tour several years already, I found an article from the June 2008 trip: Mit Fahrrad, Zelft und FTM-10SE durch Süddeutschland (pdf). After having read a book about cycling through Europe with the Rhine as one possible route, this confirms my earlier thoughts. Combining recumbent cycling, amateur radio and a nice ride through Europe is the direction I'm thinking.
Friday evening I had a contact with PI4AA via the PI2NOS repeater. So I logged the contact with those parameters in CQRLOG. After a number of other contacts I wanted to upload my new contacts to LoTW. In an upload, CQRLOG creates an ADIF file of the contacts and lets tqsl sign the resulting file before sending the signed file to LoTW. But tqsl doesn't want to include repeater contacts (those aren't valid for LoTW, so it interprets the rules correctly) and it gives a return status 9 meaning "some QSOs suppressed" which CQRLOG displays correctly. But as a result of that return code it doesn't allow for the other contacts to be uploaded at all, leaving me with a growing number of contacts not uploaded to LoTW. I reported the bug to the CQRLOG forums: Propagation type RPT (repeater) should not be uploaded to LoTW - Forums » CQRLOG » CQRLOG - bugs with a suggestion for a program fix. From my experience, good bugreports for CQRLOG will be acted upon fast. In the mean time as a workaround I mark all contacts with propagation type 'repeater' as already uploaded to LoTW to skip them. MySQL statement:$ mysql -S /home/koos/.config/cqrlog/database/sock cqrlog002 mysql> update cqrlog_main set lotw_qslsdate=curdate() where prop_mode='RPT' AND lotw_qslsdate is NULL; Query OK, 1 row affected (0.03 sec) Rows matched: 1 Changed: 1 Warnings: 0and now other contacts can be uploaded fine.
But I forgot to write about it, because I made a very minimal number of contacts: 6. I wanted to get the Veron A08 contest group using call PA0AA in the log and added some others. And on submitting the log I didn't set the category to 'checklog' so there is a result with a ranking. I got reminded today because our friendly mail delivery person brought an envelope with the token of merit (het vaantje) which is very special for this contest. The good part is all 6 contacts were valid, so 6 contacts, 6 points, 3 multipliers making a stunning score of 18, and not the last in my category! Ranking 117 (out of 122) in single operator all band low power ssb only.
After a number of recent morse contacts with special event stations I decided to participate in the CQ WPX CW contest during the weekend. Not for getting a big score, but to get experience with morse contesting. Morse speeds in a contest like this are 25-30 words per minute which I can't decode, so I used fldigi to decode most of the morse. This means I have to enter my results as 'assisted'. And 'most' of the morse is the correct description because the important detail to decode are callsigns and serial numbers. The signal report is always 599 or 5NN which is usually sent faster than the rest of the conversation because it's a specific pattern a trained morse operator hears anyway. I really didn't participate very long and still made 65 contacts. I'm not sure they all went correct, but it's a start. If I make 10 errors each of those is only 1 error for the other station. It's interesting how this approach to morse contesting gets me 65 contacts when serious participation in a digital mode contest will get me about 120 contacts. But high numbers of contacts are quite normal in a morse contest. I have received serial numbers over 2000. Logs are processed and the first confirmations via ARRL Logbook of the world are already coming in.
It's been a very long time since I was busy with pure radio frequency scanning. Being active on the sending side too has made me less interested in frequencies where I can only listen. But recently I was looking at what is available, and noticed the marine VHF channels. I could program them all in a scanner, but I decided to use software defined radio to see if anything is active in that band. Late in the evening there is currently no activity. But I set a scanner to scan all known channels and heard some chatter on PMR channels. On one channel was a remark that there was interference and they should switch to channel 14. In my memory analog PMR had 8 channels. So I looked it up and found out analog PMR was expanded to 16 channels on 1 January 2018. There is also DMR446 (same frequencies but with time division multiple access) on the same frequencies and dPMR446 with 32 possible frequencies in the same range. So now the scanner is updated with the new analog frequencies and I can hear a baby monitor, motorcycle driving lessons and a building site.
In the past few days I used the long-wire antenna with tuner to get on 'other' amateur bands. I added contacts on the 17 and 15 meter bands to several countries around my country. Some of those countries were new on those bands, so that's nice. No spectaculair new distances or countries, but a good flow of new contacts.
As a radio amateur I like sending and receiving QSL cards. QSL is the Q-code for "I confirm reception" and a QSL card is the way to confirm a contact. I have my own QSL card design and a big box of cards to send out. With contacts I usually do a check if a fellow amateur mentions the wish for cards via the QSL bureau on her/his qrz.com page, because I only want to send cards to interested amateurs. Due to the way I process my cards I can put up to 4 contacts on one card, so it's a simple optimization that if I have one contact that I want to send a card for I also check for other contacts with the same callsign. The qslmaximizer.pl script does this for the CQRLOG database.
Two new countries in the log, now the wait is for the amateurs on the other side to confirm the contact via Logbook of the World. Or maybe not, but both seemed solid contacts. First was to the island of Curacao, part of the Netherlands Antilles. A lot of Dutch stations will have Curacao in the log because the Americas are the 'easy' DX but with my antenna position it has always been easier to get to the east. Second one was to Kenia, which was a sort of surprise contact, I suddenly saw signals from a station there without any other indication that there was an opening towards Africa. In other amateur radio experiences I've also had some really nice 10 meter openings recently. This is remarkable at the bottom of the sunspot cycle, but I guess sporadic E and other special propagation modes help. So I got some new countries on 10 meter. Earlier North Macedonia and today Albania.
In my earlier activity on the 60 meter band I had a "maybe" contact to St. Lucia. This is one of the islands in the West Indies in the Eastern Carribian Sea. But in the end the "maybe" contact was no contact. Ok, fine with me, on to the next chance. That happened Friday evening in a 10 meter opening: I came to the radio with the computer decoding FT8 signals ready to go to bed, but I saw J68HZ active as only non-European station, answering European stations. So I had to try! After a number of tries I got a reply with a very weak signal report, so I kept my fingers crossed for the next exchange and it came, closing the contact. And the next evening the contact was confirmed, giving me a new DXCC entity.
