I found another source for the 2 pin plug/socket pairs... whose plugs fit nicely into the 0.5" spaced holes that correspond to the "key" socket in an Ameco...
I've been a group member for a little while, but have never posted, so thought I would at least post an intro. I ordered and constructed my first AC-1 in early...
Thanks for the story, Dave. Wow! I don't know anyone who's made contacts with an AC-1 and Ocean Hopper! Now -that's- determination, HA! 73.......Steve Smith...
Nice story Dave... I love to hear stories of you guys that actually owned and USED an AC-1. I got my ticket in 1971. I got a Viking II from a friend of my...
Never used the ac-1 but wanted too. Did use the Knight kits,both Space Spanner and Ocean Hopper in logging and confirming many countries as a SWl WPE5OL back...
Dear Ernest, Saw your post, I can sympathize on a couple of points. My wife and I are both diabetics. No real problems for me yet, but my wife had near failure...
My first rig was a Space Spanner and a Handbook 6146 Tx so that's pretty close and I made a number of contacts before adding an AM modulator to the Tx. One of...
Hello Im sorry to hear of your wife's plight.It is indeed a terrible disease.ayou can live with it but it can kill.I have been able to get my sugar from 245...
Likely asked a hundred times already but....the closest I can find in Hammond or Bud is really not ideal....any hints as to what to use here? Steve / VE7SL ...
Well actually perhaps I have spoken too soon....the BUD 1413 appears pretty usable but I only see it on BUD's web site. Does anyone know of a dealer selling...
Sometime I even amaze myself at the number of silly questions I can ask...sorry for the bandwidth. It appears that Digi Key here in Canada sells the Bud 1413...
hello, I plan to build an AC-1, but I wonder whether an HC49 would run as good as the FT243/FT241? The sheets tells that 1mW would be the max drive for HC49. I...
Raphael, from the FAQ in the "Files" section: 11. How do I avoid "chirp"? "The most significant thing that effects keying is R3 the 47 to 68 K resistor...
Will 500pf be enough, assuming I will loading into a 50 ohm load on both 80 and 40m? I see huge values used in some models...was this more a function of being...
... Steve, 500pf should be adequate for 40 meters; however, you may need to pad it with about 200pf (fixed cap) when loading on 80 meters. One way to know for...
Thanks Jim....I'll likely be running everything through my antenna tuner as well so that I can monitor actual power out as well as tweek for '0' reflected...

Hello to all: Been a loooong time, hasn't it? I recently dusted off a 6AG7/6L6 project that I finished earlier this year. It may become the subject of an ER...
Cal, Is this your valve-cover xmtr? A regulated screen may well cure the problem, but shouldn't be absolutely necessary. The screen voltage divider should be...
B+ faily stiff indeed. The p.s. is putting out around 540 vdc. I may have to revert to a half wave rectifier and see what that does. Still, the new old guy...
Hello all. I am a new member an will like to build a replica of the AC-1. But before I start I want to know a few things, I am a novice i building this king of...
Hello and welcome to the Group. The original AC-1 was designed to match dipoles with a nominal impedance of 75 Ohms. The later units with 900 pF loading...
Nothing is wrong with using that 900 pF for the plate and load caps. Don't forget some of the first gen AC-1's were equipped similarly (at least on the the...
Hi, and tnx sigcom1 and catman351 Well, I did change my mind, guess I will go for one 365pF cap and one 900pF cap as I see in other are using. And forget about...
Mark From the FAQ: 3. Where can I find 900pf variables? The original AC-1 used two 400pf variables. In these early units, loading capacitance required for a...
Here is a CLASSIC HOMEBREW NOVICE TUBE TRANSMITTER A beautifully built little MOPA rig, using a 6C4 and 5763 tube. This quality rig is complete with a 120V AC...
Hello everybody! I was thinking when you using the transmitter with some receiver on the same antenna you will need some kind of QSK unit, I would like to...
