Chris, Clemens, & All: Last winter I ran a test on the Elecraft CP-1 directional coupler. This is an Elecraft Mini Kit. I had originally built one of these units with 31 turn type 43 cores, for 30dB
Chris, Clemens & All: Just a note on the HP SLM CP1 testing. I had to use a 6dB 75 to 50 ohm attenuator as the HP SLM tracking generator output is 75 ohm, which is why the HP SLM is showing -36 dBm @
Stefan I will have my receiver and antenna setup for your 136.172 signal..... 73 Mike wa3tts Much less QRN here in EN90xn this evening versus yesterday.... 73, Mike wa3tts LF, Despite massive QRN we
Hi All: I'm not sure what to think of this.... https://www.dropbox.com/s/xwnopmbl2fz5ye5/IMG_4537.JPG?dl=0 I have been experimenting with IF shifting my radio to get WG2XJM very strong signal 10 to 1
Stefan: Yes I noticed the time and frequency were off after sending the first e-mail. I was under the assumption that WSPRX was not using a predictive algorithm for call signs, apparently that is not
Tobias: Thank you for the explanation, I was aware of the multi-part transmission format, but not sure of the significance in this capture instance. 73, Mike wa3tts Hi Mike ! Your screenshot shows St
W1TAG/1 means that many weaker stations could have made the path as well, in that time slot! Stefan & All: It was "Close but no cigar" here in EN90xn last nite. A fade at the last 30 seconds of your
Stefan & All: Finally a 630m decode at 0322..... https://www.dropbox.com/s/7dfwnxapi3cjwxd/IMG_4622.JPG?dl=0 Small shopping plaza 300 meters or so to my NE likely source of carriers and other noise..
FB Stefan: Common for XJM to have ~ 10 dB better SNRs with his large circle 8 array vs my small lot LF EWE antenna, I never expected such great conditions to prevail.... Tnx for the beaconing..... 73
Laurence, Chris & All: I did a test with my eprobe which is about 30 feet away from my HF elevated ground plane that has 65 ft radials a few years back. With 100W output on 40 meters. I was getting 1
Laurence & All: It would be interesting to take one of those Array Solutions Receiver Front End Protectors http://arraysolutions.eestage.com/as-rxfep and replace the pair of isolation transformers in
Hi All: It's been two months, since my last 630m T/A capture, but F5WK popped in at 0300 UTC... 2015-12-02 03:00 F5WK 0.475652 -26 0 IN99ef 1 WA3TTS/2 EN90xn 5971 293 73, Mike wa3tts
Stefan: Very Nice signals in EN90 this evening/morning.... https://www.dropbox.com/s/nkmcnfjpd8iaad6/IMG_0038.JPG?dl=0 https://www.dropbox.com/s/xupwslfyw8rx4py/IMG_0040.JPG?dl=0 2015-12-08 05:44 DK7
Stefan (& All): Yes, I am using a pair of reversible EWE antennas, sized 5.5m tall and 21m long for NE~SW and SE~NW directional reception. The transformers are 10.5:1 on three BN73-202 cores glued to
Stefan & All: If you use wsprx, try limiting the size of your ALL_WSPR txt file. W1VD pointed this out as the file contains a record of all of your captures. Rename the file as ALL_WSPR_OLD and then
Tobias: I'm not sure why it made a difference, but I do not seem to have upload issues with wspr-x since making the change. 73, Mike wa3tts Hi Mike ! This file is never uploaded (to the WSPR servers)
Mitch: -26 pointed NW and -29 pointed West, 3dB is about what I thought could be possible with the phasing working correctly. Very convenient to have you testing on 475 to check my rx antenna pattern
