Hello Peter, Jay, LF I had the radio tuned to 501.1kHz for a couple of hours last night but found the signal to be weakish for a close to legal limit ERP UK station under normal/good conditions. The
Hello Rik, LF! This shows great similarities to some studies and tests I did together with GM4SLV (Shetland Islands) and GI4DPE (Derry, NI) around the same time of year during the past years. We call
Hello Pete, LF I'm also plagued by a "not really identifiable" mush-like noisefloor. In my case it is not affecting RX on 500kHz badly, at least I seem to hear you guys pretty well and daytime the ba
BY255 should be a suitable building block rated 1300V PIV 3A. Use equalizing resistors in parallell with each diode, typical values used are 470...820kohm. Only controlled avalanche diodes can be ser
Here is an "in between" diode, 12kV 500mA. Available at Partco: http://www.partco.biz/verkkokauppa/product_info.php?cPath=2075_11_1012_1815&products_id=2946 BR Paul-Henrik
Mal, LF Great signal from you on 137.0kHz normal CW at 1125UTC here in Vaasa KP03SD. Antenna is a PA0RDT Mini-Whip 10m AGL and IC-R75 with no CW filter, just the PBT to keep the bandedge powerhouse s
Ha-Jo, LF Yes, you are right. 100W is the limit for transmitter output power and there is no separate ERP limit according to the information I have. Paul-Henrik, OH1LSQ Quoting hajo.brandt.dj1zb@t-on
Ok Ken Further I would not worry as much regarding the voltage rating of the equalizing resistors. Use physically large units with an adequate power rating (U^2 / R) and they will probably be fine. A
LF Marcin, Jacek , Alan, Victor Thank you all for your kind input and advice. I'm still investigating the causes of this problem. I chose to sum up my comments in one reply: I also couldn't find any
Hallo Clemens, LF +1 for good T/A MF condx. Received WE2XGR/6 loud and clear in normal CW on 507.2kHz around 0430UTC. 73 and a Merry Christmas to all! Paul-Henrik / OH1LSQ Vaasa / KP03SD
Hello Mike, LF Both visible and audible here despite no CW filter and fierce BC IMD. IC-R75 & Mini Whip @ 6m AGL 73 Paul-Henrik / OH1LSQ Vaasa / KP03SD Quoting Mike Dennison <[email protected]
Hello Stefan, LF I can not overemphasize the possible need to keep the feedline "clean" and free of RFI that may otherwise make it's way to any active whip antenna. My first attempts at deploying the
LF Does anybody else on the reflector suffer from BC-splatter on 136kHz? It has been a regular occurance here lately after dark. After some identification work I have a match on the running programme
LF Copied OE3GHB and OE5ODL around 137.7kHz about 2030UTC CW mode is LSB so frequencies are inverted. Paul-Henrik, OH1LSQ Vaasa, KP03SD Attachment: Around_137_7_20091202_2030UTC.JPG Description: imag
