Hi all, I had another sample of 183 kHz reception, around ZL sunrise, and confirm the carrier gave a solid line on Argo (30 second dot setting) for much of the time over the peroid 1759Z to 1936Z. 73
Rik and others, Thanks for various comments. Regarding path estimates: Based on the coordinates the Saarlouis TX should be in JN39IG and according to the Buckmaster callbook ZL2CA is in RE78JQ. I am
Hi all, I report quite good reception of a 183 kHz carrier around ZL sunrise this morning. I presume it is the German broadcast station, as the frequency is relatively unique, not being on the 9 kHz
Alan, OK on your efforts at installing a filtered IEC fitting in the older power supply. It is not an original idea but I decided an 'easy' solution might be to fit a filtered IEC socket into the pow
Hi all, Thanks to each who made further comments on trying to sort out the quieter parts within the range 165 - 190 kHz. Looking further ahead, if we can get our permits amended to transmit around 13
Mike, the 80 involve a The bad news is that this grey line path is likely to be VERY short duration. On 160m, openings can be as short as 10 minutes. Thus the usual long integration times are unlikel
Walter G3JKV, Thanks for your comments. .... Until you hear DBF39 you won't hear us on 136. And even then we would have to make up about 37 dB. It might be a good idea if somebody in ZL could organis
Dear Jim and other readers, Thanks for further comments on 172.0 kHz being a reasonably quiet part of the 165 - 190 kHz band in your neck of the woods. There are several participating ZL amateur LF s
Hi all, The next session of LF DX beaconing from ZL and VK is scheduled for 21 September (UTC, the "Friday night and Saturday morning" for Europe and stateside, local time in ZL is some six hours int
Hi all, My announcement omitted the call sign of Kevin ZL4MD as a participant in the TransPac tests. The following is a corrected first sentence. Would anyone publishing the material please add the c
Hi all, Following is the text of an announcement to the amateur radio media. I will email the Argo file to personal addresses, on request. 73, Bob ZL2CA A SECOND CLAIM OF ZL TO VE AMATEUR LF DX 26 Se
Jim and LF readers, Thanks for further analysis and plotting of results. My LF antenna is not very big, and has shrunk in capacitance since I did those impedance runs. I decided to "borrow" the top o
Jim M0BMU, Thanks for publishing the impedance measurements on your LF antenna. You have done a more thorough job, and over a wider band, than I did some years back on my LF antenna, but your finding
Larry VA3LK, Please, what will be his qrg? and will it be a stabilized system? We have yet to select a test frequency in the 136 kHz band for ZL6QH. It can be freely selected to within about 0.1 Hz a
John G4CNN, In response to points: Presumably the 5 watts you mention is the upper limit permitted? Yes, a ZL LF permit allows up to 5 watts radiated power. Please keep us in the picture re schedules
Hi all, The ZL6QH low frequency permit now allows access to the 135.7 - 137.8 kHz band. We need to sort out loading coil arrangements but I would expect there to be some 5 watt radiated power transmi
Pete, Hi, I am thinking of buying a new PSU, has anyone any experience with Switch Mode PSU's. Is there any sproggies on 137Kz? The PSU I am particularly interested in is the Diamond GZV-2500, any ad
Hi all, It is a fine day here today in Wellington, so there is little doubt that we will have ZL6QH running on LF from this afternoon. The DFCW emission will use 137.7896/137.7900 kHz, with 120 secon
Laurie, I published the times in UTC. The timing is for the UK sunrise on Sat 1 December, and the sunset. Most of the western European area only has the sunset phase, on Saturday 1 December. By then,
