Interesting thing to add. A participating station in a "ground wave/surface wave/ line of sight" net last night noticed a signal jump (still an S0) from a switch between an Antron 99 and an IMAX2000 of another station. I heard myself it being said the Antron 99 was slightly higher mounted than the IMAX.


The distant station noticed a jump in volume upwards and the locals said there was no difference in signal.


My longest contact with an IMAX 2000 last night was 163 miles. There may well have been a little tropo enhancement. But I was speaking to stations over 100 miles away with ease most of the evening.


There was a guy using a Gain Master very close to the ground 140 miles away near the sea side who was coming in very nicely. All signals received were voice only R2-R5 S-0 signals on USB/SSB. In the UK there are "a lot" (relatively speaking given the hobby is largely in decline) of stations enjoying this way of operating. It fills the gap between the F2 layer seasons end (and the appearance of the low in the 11 year cycle) and the Sporadic E season starting in summer where we mainly talk 1-2K miles in Europe.


I have no idea what pattern the Solarcon MAX2000 (no radials, no chokes, no ferrites) just a 10m pole and 10m of coax... is creating given the many different models but it does ok.
