Jim, I took a listen but Rugby on 73.3 was rattling away with its dirty modulation. No chance unless you're S9.... unlikely! Rugby usually goes QRT for maintenance on the first Tuesday of each month.
Dear all. Just a reminder about the LF net. Come and fight the QRM on 80m fone, 3646kHz at 1900z on Sunday evenings. The last few weeks we've been struggling for LF operators with only two or three s
Alan and all, On the subject of filter upgrades. INRAD offer an excellent range of filters, although they don't list AOR, but they are very helpful and they do take credit cards. Find them at:- http:
Geri, The link doesn't work. I found it at http://home.t-online.de/home/dk8kw/xtzyxmldo.html We've had better copy than that so maybe condx were not too good. CFH is 33dB above noise this morning tho
Dear all, Assuming that we're sticking to 1W erp then what does it matter how big the antenna is as long as the power is sufficient to give the required erp? CFH peaks 33dB above the noise regularly
Dear all. I was the other half of the QSO which started this debate, on 73kHz, I don't need FFT to work Graham on 136! I started with the 86Hz bandwidth but my PC runs so slowly that the characters w
Dear all. I understand there is an ITU paper ITU-R [Doc.3/14] which deals with Sky-wave field strength at Frequencies between About 150 and 1700 kHz. This sounds as if it may be of interest to us all
Dear all, Just a reminder. If Rugby Radio runs true to form, the 73.3kHz tx and all its lovely sidebands will be off for maintenance on Tuesday. It being the first Tuesday in February. If anyone is i
Great! Where are they all? what this letter says is, that since December 31, 1999, France has the authorization to use 135.7-137.8 kHz with 1 Watt ERP. 73 Dave G3YXM.
Good work Jim and Dave.... Snippety-snip the radiation pattern at ground >level. If the maximum radiation occurs at 20 degrees elevation, you >would have to position the measuring antenna at a height
Dear Steve and all. The PA devices in the Ropex are IRF1010N mosfets (Farnell part no. 637-397 at £3.10 each) and the driver chip, which may have gone with them, is an SG3525. Farnell part 408-359 at
Dear all. I have just added Cesare's web-site to my LF links list and it occurs to me that there may be some more that I do not know about. If any of you have web pages dedicated to your LF activity,
Dear all. I will be in GM for a few days and intend to try some QRS operation. I will have to repair the antenna so may not be on the air until Friday but, when it is fixed, I will call "on the hour"
Dear All. I have just returned from GM. Did anyone else notice peculiar conditions on Wednesday especially with shortish range signals greatly enhanced? G4GVC and G6RO were 599 in New Galloway, about
Dear all. CFH was quite strong at 2130 gmt then faded almost to nothing by 2155. It is now rising fast at 2215. Much better than usual at this time. Dave G3YXM.
Markus. 2232 71820..71817 -37dB 159 in cw (unid) someone in fast cw, no aural copy, might have been O in qrss... That was me! Sorry I didn't put out QRS at that time. I could hear nothing on RX due t
Geri. Below 72kHz seems to be quieter for us here due to the QRM from Rugby on 73.3 and all its' sidebands. If it is quieter with you somewhere else in the band then we could transmit there.. My prob
