Many people don't have the property to put up a good antenna. I myself have too many trees to make a vertical work on LF, so I am building the Ashlock loops. It doesn't matter if you have a big antenna or big amp or the best radios, this is a hobby to enjoy with whatever we can have. If you have a weak signal, it doesn't matter. Just enjoy being on LF, as it is better than not being able to operate on LF at all. By using low power or having a weak signal, it may advance the new software development, as there is a need for it with signals below the noise floor. Just look at the US operators on LF, they most likely could have never achieved the 2000+ mile receptions with the legal 1-w, without using all of this great software that so many of you generous people develop and give to us free of charge. Everyone can along from the rich to the poor and from the best-equipped station to the compromised station. Maybe just consider working the weaker signal stations as a great accomplishment on your part as being able to decode their signal. It is like chasing that rare DX station on HF that is barely readable. These are my comments and I welcome feedback both good and bad. 73's fr, Mike>WE0H http://www.geocities.com/we0h/index.html -----Original Message----- From: majordom@post.thorcom.com [mailto:majordom@post.thorcom.com]On Behalf Of Dave Sergeant Sent: Sunday, March 03, 2002 3:08 AM To: rsgb_lf_group Subject: Re: LF: RE: Diversity >>From Dave G3YMC G3KEV wrote: >Maybe your friends are transmitting on full size loops. >Let me know how you get on and try a vertical as well for comparison. As one of those 'friends' perhaps I should comment! Mal will presumably expect his large 'normal' antenna to outperform a loop at the same location unless it is very large, as he has a very large site and can erect big antennas. I have a very small site, well shielded with poor ground conditions. My loop is a means to get on the band where I would not otherwise be able to do so, and to be realistic I do not expect big results from my qth whatever I do. I have recently done comparitive tests with a 10m top loaded vertical, the best I can sensibly achieve, and there is certainly not the huge improvement Mal suggests. Details of these tests are on my website at http://www.dsergeant.btinternet.co.uk/vertical.htm. It may be that the vertical is not optimised, and in anycase is difficult to get clear of vegetation etc - the very problem Bill Ashlock in the USA has which he has overcome with loops. There are some signals which I can hear better on the vertical, but they are few and generally in the direction of the loop nulls, and in a typical urban location local noise normally makes the loop the best all round antenna. No big expectations of dx here - if Mal can only just hear me he should remember it is 325km and no mean distance for my set up. It may be a compromise, and certainly does not perform like some setups do, but the loop does at least get me on the air from a difficult qth. I am currently building an Elecraft K2 10W hf transceiver. When that is complete shortly I shall devoting far more time to the hf bands. With normal cw activity on 136 at an all time low I can no longer devote all my time to that. 73s Dave G3YMC dsergeant@iee.org dsergeant@btinternet.com http://www.dsergeant.btinternet.co.uk
