Mike also wrote: > If I had been restricted to 5W in my early days I would have given up long ago, > and I am sure that Steve would have done so, too. I'm sorry if I conveyed an impression of 'restriction' in my earlier Email. What I really wanted to demonstrate was that newcomers to 136 kHz could use QRP as an 'entry level' stepping stone to this fascinating band. Let's go back to mid-March 1998, and consider my own experience. Using a less-than-optimum receive set-up, GW0GHF (42 km) was the first station to hear my 15 W signal on 136 kHz. At the time, I was using a very poor single-turn loop antenna: tuned by very lossy capacitors; and fed by a very lossy balun (wound on an EMC-grade toroidal core). By the following week, I had completed my first QSO with Graham G3XTZ over a distance of 157 km: with me still plugging away with my 15 W into that same loop - fed by a rather warm matching network! For me, that QSO was my stepping stone. > Be realistic: If you have a 40m dipole, 8m above ground and strapped as a > Marconi, over poor soil, you are wasting your time with 5W. Wow! I wish I had such a big antenna! I wonder how it would perform against my 12 m vertical (with no top loading)? Seriously though, 5 watts into a small antenna can still make quite an effective set-up for those first LF QSOs across town. I trust that I have proved this to be the case. I'll leave it to others to decide whether I was wasting my time. Regards to all, Steve GW4ALG
