There's a very nice (and pretty standard) design for a pair of 4-250's (or 4-400's) in the '59 (+,-) Handbook. I have a complete set of parts (finally) for the RF deck and a companion modulator deck. Doesn't cover 160 as is, but if you need it, it shouldn't be a major mod.

Re: [AMRadio] 75 Meters Long Already
Hello Jack, > What am I missing? What is wrong with "long skip"? Nothing, as long as it's not your only choice. Normally, you can "generally" choose your skip distance by selecting the appropriate band for the time of day. 20 and up for longer distances. 40 short during the day and longer at night. 75 and 160 for shorter distances. ...there are exceptions of course. For the last few months, we've lost the choice of short skip on 75 at night. 160 is difficult for a lot of folks, antenna wise. So... No more talking to your buddies within a couple hundred miles late in the evening or night. 73', KA5MIR On Sunday 26 November 2006 21:44, Jack Schmidling wrote: > > In a message dated 11/26/06 3:27:46 PM, [EMAIL PROTECTED] writes: > >>Have you guys in the N.E., East & West coasts had the same lack of > >>short skip on 75 after dark? > > I do not understand this discussion and am not sure if it is good news > or bad news.

Re: [AMRadio] New Transmitter
Check out either amfone.net or amwindow.org . Tom, K1JJ, I thought built a pair of 813's X 813's triode connected. I don't think it was link coupled though.

RE: [AMRadio] 75 Meters Long Already
Nothing wrong with "long skip" except when you're trying to work stations close in between 100 and 600 miles. If I wanted to work "long skip", I'd work 40 or 20 M. 75M is supposed to be for "short skip", and "local" work, not specifically DX.

[AMRadio] Sunspots are coming, too
Just in time for Christmas-vacation tinkering: Item #1 Johnson "Whiteface" Messenger 1. NOT a CB rig, dangit! It's a "Ten Meter Rig, Awaiting Conversion", (just happens to have some CB crystals inside). No mike, but has a stub cable with Amphenol connector for one. No power cord and you'll need an RCA adapter for the antenna jack. Good shape and looks complete, but untested. I can at least provide power connector info. $25. Sunspots WILL return! Item #2 - Johnson "Blackface" Messenger II.(or "2", or "Two", whatever) This is the hot deal with Tunable receiver. Has a Turner mic wired in but missing the p/s cable and RCA antenna adapter. Good shape and looks complete, but untested. $25. Lord it over the poor saps who have to buy receive crystals! I'd prefer Paypal but can take other forms of legal tender. Prices do not include shipping, which will of course be at actual cost, naturally.

Re: [AMRadio] 75 Meters Long Already
This past Friday night was the best for short AND long signals on 75 that I've seen in several months. No problem talking to locals in AR, TX, OK and at the same time KL7OF in WA, New England, CA, etc.. I had big hopes for Sat night but - nope... back to long skip only. I've been off the air for 5yrs. I don't remember it being this way back then except very infrequently. Sunspot minimum, I guess... Very disappointing. Have you guys in the N.E., East & West coasts had the same lack of short skip on 75 after dark? 73', KA5MIR On 11/26/06, Mike Duke, K5XU <[EMAIL PROTECTED]> wrote: at 4:45 PM central time, Dave, W9AD is stronger into my Mississippi qth on 3885 than he usually is on 20 meters during the summer.
