Hello Jim and group, successfully decoded the Jason signals from M0BMU on friday night. The 400mw ERP signal was audible, but frequently interrupted from strong static crashes. Interestingly the wate
Hello Jim, RRR - here at least one report: Sorry, didn't successfully decode you yesterday. There was "something" on the waterfall but not you I'm afraid. Will try again tonight from the club station
Dear Jim, Alberto, Stewart and Group, Just played around with Jason V0.94. Phantastic ! Perfect decode of an old wave file recorded in a previous test transmission from M0BMU which gave no copy at al
Hello Jim and group, signal level - here you have to take care not to adjust the RX gain (and keep the AGC turned off) between calibrating and measuring. To interpret the noise level you would have t
Hello Walter, Markus and group, thanks for triggering the activity. I took a miniature direct conversion RX with a ferrite antenna to the office, and so could observe the CW transmission the whole da
Hi Andy, Thanks for the info. I will take a look for other controllers, possibly a "MicroConverter" from Analog Devices (8051 core, 8k FLASH, ADC with 12..24 bit resolution). Disadvantage: 52-pin PQF
Hi Johan, Grumble... I was just going to get QRV on 80 meters again, but horrible wheater made listening impossible (lotsa static crashes). Will the Jason QRPPP becaon reappear ? Regards, Wolf DL4YHF
Hi Sandy, from own experiments with several soundcards I found only marginal differences as long as simple waterfall display is concerned - so I confirm Alberto's comments. (Instead of a bit more dyn
Hi Walter, Markus and Group, ufb, already looking forward to the event. Will try to connect a small light bulb to the long wire, tuned to your frequency; hope you get it to glow ;-)) 73, Wolf DL4YHF
Hello Giulio, Here a translation of the text below DF8ZR's diagram: The Circuit The picture shows the classic design of the three stage amplifier. Only commonly available parts were used. Only the co
Hello Geri, Wil, Fabian and others visitors of the German-Netherland's amateur meeting in Bentheim, I received some mails directly addressed to me, and as some of you don't use such evil Unuseful Hig
Hello everyone, Just a quick reminder that coming Saturday (Aug 24) there will be a hamfest in Bad Bentheim, close to the PA/DL border, near Enschede. It would be nice to meet some friends of LF ther
Hello Brian and Jose, Congrats for another crosspoint in "The LF Matrix" ! A tough job transmitting slow CW by hand - I also tried that once, having no connection cable between LF rig and the noteboo
Hello Group, Sorry no reliable trace from ZL6QH here in the northwestern part of DL. WX very bad this time of year (QRN, sferics). Looking forward for the winter season, at least for the sake of LF.
Hello Group, Thanks to Matti's Info, I found this website which may be interesting for you if you also have an old OXCO in your junk-box: http://www.vectron-vti.com/products/ocxo/ocxo_archive.htm Unf
Hello Matti, Brian and others, Thanks for the info about the OCXO. Think I will carefully 'dremel' it open to find out. The enclosure is brass so should be possible to solder it later. Regards, Wolf
Dear Group, I am also looking for details for a 10 MHz OXCO(?!) which I bought at the HAM Radio fair in Friedrichshafen this year. The dealer did not have much info about it (i still await his email)
Hi Alberto and group, Jason V0.95 successfully downloaded and installed, looks fine. Also pleased to see the decimated file logging function at work - I will do some compatibility checks with my own
Hi all, Copy on Johan's beacon gets worse though the noise (QRN) gets weaker. Shortwave is so much different than LF.. see attached image. The 7 MHz signal suffers from multipath, every Jason symbol
