Dear Dave, Gary, Jay, LF Group, Thanks for the comments - Yes, with a bit more work I hope to convert this into a publishable article. As far as achieving the "legal limit" ERP goes, the UK licence r
Dear LF Group, I have now finished the antenna experiments that I started earlier this week - this is a summary of the results. The idea of the tests was to measure the effects on LF/MF antenna perfo
Dear Lubos, Mike, Graham, LF Group, Thanks for the reports - I was doing some antenna tests, as part of the programme in my Special Research Permit application for 500k. The 1/2-space DFCW setting is
Dear LF Group, Thanks for the comments... indeed I have just re-calculated the ERP based on values of Rrad obtained using a NEC-based antenna simulator (MMANA-GAL). This should give a more accurate v
Dear Graham, LF Group, I think that is the correct locator - will check later Hopefully, the antenna won't have a chance to dry out and need re-tuning! The mains power is via about 130m of cable to t
Dear Lubos, LF Group, Thanks for the screen shot - yes, that is me doing some more antenna experiments... Cheers, Jim Moritz 73 de M0BMU -- Original Message -- From: [email protected] Lubomír B
Dear Rik, LF Group, I think the main effect of having the elevated loading coil is too reduce the voltage on the downlead of the antenna - this would have two advantages: -Reduced voltage on the down
Dear David, LF Group, There are plenty of broadband active whip designs that will work up to 30MHz or more, mostly depending on the amplifier bandwidth. I imagine an issue with using such a design on
Dear LF Group, The WOLF beacon is now running again from 2200utc. I am now using WOLF 20 mode, "by popular request". Frequency is 503.800 as before - any reports welcome, or comparison with the previ
Dear Rik, LF Group, Congratulations on your first QSOs on 500k; I think I just missed you on 503.0k - I heard the end of a call at quite good strength around 2200utc and then no more. But there will
Dear Jay, LF Group, Normally I leave the beacon running until the morning - around 0900utc. I hope to be putting out some kind of signal most nights until my 500k experimental permit expires on Febru
Dear LF Group, Thanks for the reception reports from last night. I will be runing the WOLF 20 beacon again tonight on 503.800kHz from about 2200utc. Cheers, Jim Moritz 73 de M0BMU
Dear Wolf, LF Group, Thanks for the report from last night. I will run the beacon again on 503.800kHz, WOLF 20 mode, from around 2200utc. Cheers, Jim Moritz 73 de M0BMU
Dear Graham, LF Group, Decoding your WOLF signal now - frequency appears to be 502.7980kHz, which is quite a long way off nominal for this mode. It could be down to either TX frequency accuracy, or s
Dear Jean-Pierre, John, Hartmut, LF Group, Thanks for looking out for the beacon signal last night. I will run rhe beacon again tonight from about 2200 (503.8kHz, WOLF 10) - at least on 500kHz you do
Dear LF Group, Does anyone have an e-mail address for Doug, G3ZWH? I had a QSO with him earlier, and said I would send him some info. Cheers, Jim Moritz 73 de M0BMU
