Jer & Fred,
You're right from a certain point of view. But also consider more generally that it's about link budget; maximize gains, minimize losses. How much of each a ham can do comes down to money & motivation within lifestyle (& FCC!) constraints. 73, Mike ab3ap On 08/01/2016 01:47 PM, Fred Moore wrote: > I'm with you Jer.. > > I always wonder that some of you guys "cost/QSO" is.. it only a hobby, > [...] > > Fred > > > On 8/1/16 9:50 AM, Jerry Moore wrote: >> I don't see the point of having a large power amp.

I have no interest in a 1500W amp ... even one made by Elecraft.

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!

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.

We just differ in opinion and I’m happy for everyone to enjoy the hobby as they are able. The issues I see is where the Amateur code is broken. Just listen on DX pileups sometime and you’ll hear guys that really make us look bad as a community.
About the only time I can imagine someone needing power is perhaps a DX station but that’s IF they can actually hear. Doing the math I am probably missing something because I don’t see much of a gain from 500w to 1.5kw into the same antenna system. From memory 500w to 1k is 3db and 1k to 1.5kw is 1.5 db, so 500w to 1.5kw is 4.5db 6db is 1 S unit (from memory) so running a 1.5kw amp gives just less than 1 S unit. Now start factoring up the DB gain/loss for antennas/feedline. Which gives the best bang for the buck?? Maybe I’m just slow. Seems to me a nice, instant on 500w solid state with quality low loss feed line into a matched antenna should rock and roll. This thread should probably die. Enjoy the hobby as you wish. Just know any station who worked em with less power just owned you regardless of your budget 😊 Sent from Mail for Windows 10 From: Mike Markowski Sent: Monday, August 1, 2016 2:03 PM To: [hidden email] Subject: Re: [Elecraft] The 1500 watt amp Jer & Fred, You're right from a certain point of view.

That would be a no for me. Money is not the issue. Just do not need more
than the KPA500 I now have.

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. And not fully appreciated. > On Monday, Aug 1, 2016, at Monday, 2:28 PM, Ron D'Eau Claire <[hidden email]> wrote: > > ...

Nice work!
I too have built my own enclosures with similar techniques. A couple of my projects can be seen here: http://sadxa.org/n7ws.html#amp Although at the time I had access to a prototype workshop, I have done similar work at home with comparable results. If possible, I avoid bends. In all of this stuff I used 0.062" 6061-T6 material so it wasn't going to bend anyway. The harder alloy drills like a dream. For all of the corner joinery I used 3/8" square stock, 8/32 threads and stainless steel screws In the protoshop, I had access to a shear but all of the sheared edges were still smoothed by hand. I had a granite surface plate and used a vernier height gauge for layout so similar parts were interchangeable. In the home shop I lay out as carefully as possible and match drill on a drill press. Most people can't tell the difference. With a lot of elbow grease a hacksaw works, although after a lot of furniture building and finish sanding, I needed rotator cuff surgery so I don't do that anymore. With extreme care and I do mean extreme, a carbide toothed blade on a table saw will cut aluminum if it's thick enough and the blade has fine enough teeth. Otherwise I use a bandsaw, which is always safer, if less precise. In the protoshop I had access to chemical dip baths for passivating the aluminum, silver plating the RF parts and a panograph engraver for panel lettering. Silver looks nice, but is highly overrated as an RF conductor.* In the home shop, before the un-elected bureaucrats in DC decided we were too stupid to handle lye (judging by the electorate they may be right), I would etch aluminum in a lye bath, rinse and neutralize with vinegar and a final water rinse. This would yield a nice satin finish. The best I have found since is oven cleaner. Another finish, if you like the look, can be had by using a random-orbit sander Play with the grit until you find something you like. Sanding it wet with a little cutting oil can be fun, albeit messy, too. Tube amplifier still have their virtues and, along with antennas, can be great roll-your-own projects that can work better than what you can buy.

Nice variation on "It was a dark and stormy night ..." Bulwer-Lytton

If cost per QSO were a concern, no one would ever work EME. Just sayin'.

You do. My alter ego is a wannabe author. Unfortunately time is a zero-sum game (think Jake and his Avatar). Cloning would be a better solution, but it's not in my budget.
