[Elecraft] Crowdfunding a 1500 watt amp - SURVEY?

[Ron D'Eau Claire]

A serious mistake some antenna-limited Hams make is to try to make up for a poor antenna near the ground with more power. A situation like Jim brings up would likely produce a number of ill effects such as:

1) Producing interference in many nearby pieces of equipment from Hi-Fi systems to DVRs, broadcast receivers, etc.

2) If the antenna is not carefully insulated and isolated, animals and people can receive very painful RF burns and in the extreme set fires. For those who have not experienced a severe RF burn, it instantly creates deep tissue damage that is very painful for days or weeks afterward.

3) Short antennas (whips, short wires, etc.) easily produce corona discharges at their ends that distorts the transmitted signal and creates broadband Hash across the ham bands. 

4) It becomes very difficult to ensure people are not subjected to excessive RF exposure if the antenna is not up high and in the clear.

Wayne, if it turns out to be a survey, put me down for a NO vote. I run my station in a HOA/CCR neighborhood and use thin, stealthy wire antennas. I’m surprised they don’t vaporize as it is with the 500 watts or so coming out of my KPA500 - on the rare occasions when I do run QRO!

(p.s. - and another reason for a no vote is that I’d be talking in a much higher tone if I told my XYL (KF6ZNT) if I was gonna buy a big buck amp!)
