Martin, you may want to subscribe to the GQRP club. Their quarterly magazine, SPRAT, has many good articles especially for CW and for folks who need to operate with very compromised antennas. I think the UK folks are the masters of getting on the air successfully from very small gardens and community restrictions. I was very successful operating from my daughters house on 40 metres with wires laying on bushes with an average height of probably 3 metres from her very small garden, which was mostly surrounded by other tall stone buildings. You can get a CD with 184 back issues of SPRAT where many of the articles are for simple home brew rigs and antenna ideas. Warning, these antennas worked for some folks for sure, but most would probably not pass muster from the technical gurus on e ham. If I wanted to work DX, I hiked up into the hills with my battery power QRP rig, and could work thousands of km on 20 meters and even occasionally spanned the Atlantic back to the US. It was much more fun rag chewing with a ham perhaps a few hundred km away on 40 with good signal reports, than a quick DX "QSO" with a RST 339, tnx QSO, QSB, 73, however any place I travel, I usually much prefer operating portable from a park or trail, than from any urban area. I look forward to my next trip to the UK, where we will spend much time in remote Wales where some of our relatives have recently relocated. Cheers, Rick KL7CW
