From what I can see thru messenger Carl hasn't been online in like 2 days. As my last messages are not even received yet. So I hope he is well.
Probably stick with SSB with it for now. Or run the 296 with it if I decide to do AM mode. Like you said I don't like the high SWR either. Still...
Here is the SWR on lowest 3/4w dk power with amp on.
Here it is with higher 7-8w dk and amp on. Shows as 1.9:1 on the radio display. I still get about 50-60w I'd swing on PEP mode. To like 475-500w.
Starts at the 175w dk and swings to like 350w pep with the 3/4w dk.
So I opened up the 6666. Lowered low power to like 3/4w. Lowered HI one also to like 15w. (Was at like 18w dk)
3/4 swung to like 4w with PEP hold on to get the pic.
on low 3/4w I get like 175 dk on amp which is under his 200w dk mark. Just still think something is up with the AM "tune"...
Radio and amp still up for sale. For $150 shipped this is a steal. PayPal preferred.
I can send invoice to you. Just message me your PayPal email address.
Just moved to NJ (as some know), so money orders won't work for me as I don't have a NJ ID yet as I still have a PA one. And I'm not at...
I will probably try to adjust the AM low pot on the 6666 to knock it down abit. I don't see how 1w extra on dk can make a 10 fold increase on the Amp dk when on.
I did notice in Carl's videos his Cobra 29 has like 0 w dk and then swings to like 30w. So I'm guessing he has a swing kit. That may...
Ok. Here is my Ranger 296 numbers. 3/4-1w dk on AM swings to 5 1/2 pep.
Gets a very tiny 20w dk with AMP on (meter on 200w) and swings to 350w (peak hold is on for this shot) (meter on 2000w)
So at 5 1/2w I get 350w pep. Which kinda lines up with the 250 for 2w dk. (n):unsure:
the lowest the AT 6666 will go is the 2w as shown. (was turned down inside when I had it setup for me). Just can't figure out why I'm hitting such a high DK with amp on and only 2w dk. Even my old 4 pill Palomar I just sold didn't get that crazy high of a dk. Hence me scratching my head.
just wish mine would kick on at all. Hasn't which I would think is odd. Also as noted before my voltage seems to drop and fluctuates according to my meter. Like 14.2 down to like 13.9 (which is the .2 in the manual) to 11.8, like it bounces.
Made sure like 50x that it's set to "fixed mode".
(n)Ok. Here's the radio AM DK on lowest setting. Like 2w. Swings to like 14w pep.
Amp on DK (like 260-270w). Swings to like 450-500 pep.
Reading online about some competition HD amps can take upto 200w pep (which is this ones spec). Some actually due start with a high DK and go up from...
Only downside this far is fan level. Kinda loud. Great air flow. Moved to top shelf. PS is on bottom. I'll take the nice easy swing to 500-525 without hollering in stride though.
The AM has me miffed abit. With my low drive radio (Ranger 296) which does a 1w dk and swings to 6 1/2w on AM I get...
30w of PEP from the 6666 gets me easy 500w PEP in SSB mode. Happy with results.
Amp is on the PowerMax 100 by itself at 14.20.
Got good audio reports thus far on 2 DX contacts. One in Ohio said I went from a S5-6 to S9+ over barefoot. I'll call that as a win.
Turned up SSB power for briefly...
What I noticed with just the AT-6666 hooked up tot the PM3-100LK is about a .02 in voltage drop when keying the radio and swinging to like 50w on AM or SSB. And yes I am in "fixed" mode.
Anyone else that has this model able to measure the voltage drop when running any real amps thru it?
I...
Powermax PM3-100LK came in. Was set at 14.4v on the fixed setting. Set it back to 14.1vDC
Will test for noise later on. Have my 2yo son here and he's a handful.
I'm including the 2nd bracket as shown in the pic also. So if you have a truck you can just mount up. This allows some air gap above the fins of the amp. Pic was taken on install day. Thats dust on the clear plastic film.
Drop to $150 shipped for the setup. That's like $80 for the radio and...
I managed to get a NOS 78XL and RFX-95HD today off the "bay". Both show shipped as well directly to my normal tech.
Selling my Uniden 980/203 combo to offset this cost some. I just want a basic AM rig I guess for my truck. Classic Uniden look with a kick should do the trick.
Be a week or two...
