Hi Markus 8K19A and 13 characters. TX just started. Joe Great! What type of coding (8K19A ?) and how many characters will you send? 73, Markus Greetings LF, I hope to send to send the name of the cat
Hi Group, The DDS only works on 136.5 so this will take some time to fix. Will try again some day soon. Thanks and sorry for the disappointment. Joe No worries Joe, no hurry. Weekend's over and we'll
Following last night's misadventure, the VLF/LF/MF exciter seems to be recovering. On VLF, CW on 8.277 kHz was heard at just over 1 km using a crude DC receiver and a miniwhip. NAA on 24 kHz was loud
It seems the Arduino refuses to accept long messages and the cat is getting quite fed up with excuses. An 8K19A sequence with 7 characters & 2 second long symbols was started around 2300 (I hope). At
Hi Paul, The tuning coil is rather small and lossy. The best range is 5 km using a DK7FC E probe and Spectrum Lab with QRSS100. I don't have a GPSDO yet, but Markus says the dual oven osc should be s
Hi Domenico, Thanks for watching. 8K19A 2 s symbols 7 characters. Next start time 0000 UTC 24 Nov. Just started! 73 Joe VO1NA Hi Joe and all Group. I'm also recording around 137777.00 Hz and i will t
Hi Paul, Markus and Domenico, Group. There is sill something fishy in the Arduino, but there is one less instance of shoddy programming. Please forgive me. My cat is about to disown me because of my
Well done, Markus! (your RX and assistance to me). She's delighted and her faith in me restored. Thanks ! Joe, got her! Partial decode of the first half of the first transmission, at 21:10. Ver
Hi Paul, EbNaut is amazing. There was some arcing with the aerial so I've switched to the old one. Thanks for your patience and all the fun. Joe Success! 21:00 message decoded re-encode 130/608 ber 2
Hi Domenico and it's impressive that the signals reached you so early. Tangles is a big fan of Marconi! She's delighted her name made it to Italy and your's truly is very grateful for the report. I'v
The timing is off by a few seconds: the 2200 sequence ended at 22:20:19. I think the old antenna is several dB down and that isn't helping things. Oh well, at least the message arrived! It was very m
My timing is off a bit too. I expected a 0.1 - 0.2 for the propagaion delay of CHU and about the same for my reaction time, but a whole second seems like a lot. It's time to get GPS or a clock from t
Markus Paul and Domenico, Group I have new message 5 characters 512 symbols and hopefully corrected the timing offset a bit. Will start in 1 minute at 2000 utc and on the half hour. Running 50 watts
Hi Andy and thanks for tip of putting the diode across the gate of the PA MOSFET in your posting a few months ago. I'm using the class E amp at the moment. The XOR can idle with high output so I deco
Paul, The exciter quit sometime during the night. Perhaps around 0400! Nice numbers for 50 watts and poor timing on my end! I know someone who might have a source of GPS PPS to correct this problem.
512 chars, 2 seconds each, duration 17'04" What is the duration of these transmissions, 512 chars at what rate ? Andy I have new message 5 characters 512 symbols start in 1 minute at 2000 utc and on
Hi Andy and Paul, Happy to hear of your decode, Andy. As for the clock, I actually had to reset the system because the pause time was incorrect. The 2030 one was started by yours truly listening to C
Hi Markus, Good to see that the low power bits are arriving. The clock seems to be slow by 400ms which will be simple to fix, unless something else goes wrong. An output 12.21304 dB lower in frequenc
Hi Markus, My aerial current is 170mA so 3.5 uW on 8.3 kHz! Nice Eb/No values, Markus. Getting ready to start EbNaut again, hopefully with the timing offset reduced. Intended start time 2000 UTC. CHU
