Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?
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.

Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?
Nice work, Ken. On the amps and the cars. I was wondering the same thing about "rolling your own". I suggested that doctor who said he could build pretty much what he wanted could build the enclosure. He owns an electronic lab which builds his stuff and farms the enclosures out to another professional. Not sure subcontracting is the Ham Spirit, but we're all in this hobby for different reasons.

Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?
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. 73, Ron AC7AC -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of James Bennett Sent: Monday, August 1, 2016 11:23 AM To: Elecraft Reflector Reflector Subject: Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?

Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?
Huh? How does my situation even closely border on producing “ill effects”? This is NOT the situation here, so let’s set the record straight. 1) My stealthy wire doublet is 45 feet in the air. I experience ZERO RFI problems even at the 500 watt level. Nor do my neighbors, who I’ve asked several times if there are issues. 2) I would be interested to see what sort of person or animal is going to come into contact with an antenna at that height. Actually, maybe I don’t want to see - might be pretty scary sight. 3) Don’t know where my post mentioned whips or short wires. None here at this station. 4) True, but again, not here. My post simply was intended to convey my desire and reason why I do NOT want to run any more power than I already do, and any correlation of my installation to someone with a dipole five feet off the ground or experiencing RFI is off the mark.

Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?
Sorry Jim. What I was referring to were your words "I run my station in a HOA/CCR neighborhood and use thin, stealthy wire antennas." I'm sure you realize that many Hams in that situation have antennas running along fences, even sometimes indoors, or short whips and loops on a balcony. It's good that it doesn't apply to you specifically but a great many Hams in an HOA/CCR environment must live with a "stealth" antenna systems like those. 73, Ron AC7AC -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of James Bennett Sent: Monday, August 1, 2016 3:05 PM To: Elecraft Reflector Reflector Subject: Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?

Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?
Ron, No offense taken - I understand your intentions for the reply. Low antennas are a formula for trouble if proper precautions aren't taken. Common sense "should" come into play, but we've all seen or heard of examples of hams so focused on the antenna itself, they fail to think about what might happen if it falls, someone touches it, etc. And who knows, maybe we'll meet on 30 meter CW - I hang out there quite a bit, too! 73, Jim Jim Bennett / W6JHB Folsom, CA > On Aug 1, 2016, at 7:54 PM, Ron D'Eau Claire wrote: > > Sorry Jim.
