From Dave G3YMC Note the change of thread name..... 1. I would personally be very happy if the attachment size limit was reduced even more. Most of the recent .gif attachments have no interest for me

In fact this will do absolutely nothing with the Badtrans virus. It and a lot of the current viruses do not glean their email addresses from your address book - rather they get them from messages in
I assume on this frequency it was a test transmission. If he had been looking for a QSO he would have operated in the data section (137.4-137.6). See http://www.g3wkl.freeserve.co.uk/lf/136kHz.html 7
From Dave G3YMC Bandplans are an attempt to all users of a band to operate in harmony without causing each other interference. I would hope you would see these comments in that light! For instance, o

From Dave G3YMC I wasn't going to comment, but I will. The current bandplan may be unofficial and a gentleman's agreement (as surely all bandplans are) but it gives a bad impression if a key operator
From Dave G3YMC Andy will find an updated version of the huff and puff, using a CD4013 counter, in Technical Topics in the April 1978 issue. This is a reprint of the version which appeared in Ham Rad
In our country units that are derived from the names of scientists are written with a lower case letter; for instance volt, >ampère, watt, etc.; not Volt, Ampère, Watt. When abbreviated we use a cap
From Dave G3YMC My loop has been in use for well over 3 years now, so the following may clarify recent discussion and surprise some used to 'conventional' vertical antennas. 1. Loops are largely unaf

From Dave G3YMC Clearly the use of large transmitting loops is outside the terms of the lowfer licence in the US. However use of a receive type loop with many turns of thinish wire (litz or not) for

I heard CFH yesterday afternoon at over s9 - not far off the signal I copy it (when it is on) at dawn. Normally when I hear it in the daytime it is much much weaker. Are we sure we are listening to C
I have received a message via GW4ALG from Ron G6RO to say that the strong winds of this week resulted in damage to his LF antenna, and Ron is currently QRT on 136 kHz. He will repair his antenna syst
The type of capacitor to be recommended for matching loops is the Philips 386 polypropylene series. Readily available in Europe in 10/22/47 values from 1nF to 100nF and above in 1kV and 2kV ratings.
There have been a number of instances recently (one today) of spam being sent via the lf reflector. The reflector is in fact configured so that anybody can post (try it with one of your alternate ema
From Dave G3YMC It is good that there are now several on the reflector taking a re-look at loops. However I feel there is far too much 're-inventing the wheel'. There has been much information about
From Dave G3YMC I hope that is just an example. If you really have a transmitting loop with a series R of 5 ohms you are wasting your time. Mine has a dc resistance of around 0.1 ohms, and an effecti
From Dave G3YMC The main problem with transmitting loops is the enourmous current and Voltage which is generated when exciting them with decent power. It's all very well to put 1W into a loop but try
