Bill,

 Not only was I on my HB Mag-loop, I was In my Basement shack.

Flex3000 @ 5 watts and HB Mag-loop.

It was designed for 20 - 10 but the Air Variable can pull it down to 40.

According to the design program, It only has 14% efficiency on 40 also.

Sure glad you hung in there and pulled me out.

Just goes to show, When all else fails, CW will.

FS: Ten Tec 6M xvtr 1208

FOR SALE:

Ten Tec Transverter - meets or exceeds specs of:
.15uv rx sens and 0-8 (10 w resistor change) watts out with 5 watts from a 20m xcvr.
That makes it perfect for almost any of the radios we use.
  The best about this is the wonderful manual included, that has a significant amount of
intro info for the new 6M enthusiast. I wish I had had the manual when I started on 6m.
The manual should be priced at $25 with the xvtr at $35.
If you have been watching the propagation predictions...
6 has been open a lot lately. Don't miss out on the fun. Here's your chance.
I'll pay shipping, if you want to get in on the 6m action right away.

Have a great day,

Totally awsome! The set-up was the KX-3 this morning, with a PPK minikey into the mag mounted antenna, Terry with that set-up I'll take the 559 oh yeah!
I actually heard Chas call in, you were about a 339 Chas, nice signal.
Thanks again Terry, my day is now much improved.

Hi Terry and the gang,
Well I had an unexpected opportunity last evening and wanted to try to get in on the 4State 80m net. Terry struggled mightily but hey, I'll take the 559! even if it was in between static crashes... There was an awful lot of noise on the band, I'm guessing that the crashes were lightning strikes out to around a thousand miles, well that's 80 on a summer evening I guess.
So, I dragged out the HW-8 and the ZM-2 ASTU, hooked up the W3EDP and had at it. Thanks for sticking with it Terry, in between signals you were an excellent 579.
HW-8, ZM-2, W3EDP antenna, it doesn't get much simpler than that, check out the attached pictures. The power out was a healthy 1.25 watts (QRPOmeter pic attached), yes that's a notebook and pencil for logging.
Hope to log in to the Thursday AM net this morning from the works car park.
Vy 72/3 es God Bless all de Wayne - KC0PMH

Well, rumors of my transformers death were exaggerated. It turns out the smoke was real, but the death had not occurred before I shut down. At the suggestion of the electronic shop owner I buy my parts from, I verified my output voltages from the power transformer.

So, today I replaced the electrolytic capacitor and found two new tubes (well new to me) replaced them on the radio. I still need to add the fuse. But it does work and I am getting close to 10 Watts. As soon as I get back up to speed with my Morse code I hope to get on the air. Thank you all for your suggestions.

Re: AMECO AC-1 issues

sigcom1
 

Sorry to hear about the PT in your AC-1. The problem might have been caused by a shorted 6X5 rectifier. Although I've never experienced it with any AC-1, the 6X5 has a bad reputation among the antique radio enthusiasts with shorting and taking out the power trans. (un-fused primary).

The AC-1 PT spec's are as follows:

Secondary voltages without load:

6.3 V filaments AC

300-0-300 V AC nominal. This generally varies from 290-0-290 to 325-0-325 depending upon line voltage.

Dimensions: 3" wide x 2 1/2" deep x 1 3/4" high. Stamped
with "T-141" or "T-141 H" on the end bell.

This info is from the "AC-1 FAQ" document on the AC-1 Yahoo Group.

<https://groups.yahoo.com/neo/groups/amecoac1/info>

The above voltages are from measurements. To the best of my knowledge, voltage and current spec's. for the T-141 have never been published. 40 mA on the HV secondary would be adequate and whatever the combined currents for the tube heaters is.

Best of luck with the project and

Re: AMECO AC-1 issues

Not a problem. I blame most of my typos on my tablet's auto-correct feature .

I did a little checking and the rectifier was the tube that was arcing (little lightning like sparks between conductors internal to the tube) and the 6V6-GT never got warm. I think I will start working with the power supply tonight and see how long it takes to get to the rest of the circuit.

Dave, your right! There is a failed component downstream of the transformer and I'm sure the transformer was an induced failure due to this problem. I noticed one of the tubes was had arcing inside the tube instead of the normal glow and the other tube didn't seem to have any power (no glow). I believe there was smoke coming from the electrolytic capacitor after I pulled power as well as the transformer. It looks like I will get to spend some quality time with the whole transmitter before I apply power again.

Re: AMECO AC-1 issues

And I would put a fuse somewhere in the circuit, probably a slo-blow due to the high inductance of the transformer.  You might consider putting one in the secondary circuit as well.  Fuses are cheap.

Before you replace the transformer, you should thoroughly test the rectifier and filter capacitor.  My first suspicion would be the capacitor.

Re: AMECO AC-1 issues

There is a Yahoo group, of which I am a member, that is dedicated to the AC-1 and the cult like following of this rig.

You will find all the information that you need and more to find a replacement transformer and all manner of things you never knew about the AC-1 .

I HIGHLY suggest that you become a member.

The AC-1 was the first kit, as a Novice in 1965, that I was able to buy for around $16. That was a LOT of lawns to mow in those days:)

Loved the little rig but it got away from me and I have never been able to afford to replace it. I had upgraded my license and rig when a new Novice, "borrowed" it and it never returned.

Best 73,

Charlie, W5COV

A fuse would have been a smart move. I replaced the rotten original power cord, but had neglected to add a fuse . Pretty dumb for a safety engineer. I'm not certain where the circuit fault is, but the transformer sacrificed itself to protect the cheaper downstream parts.

Thanks for this information, I will start looking into obtaining the components.

Hi Bobby,
Glad you're having fun with the rig.  I do not know the lowest voltage but considering the circuit, I'd expect it to be no lower than about 11 volts.  The lower the voltage, the more current it will draw.  It runs just fine on a 12 volt battery though.
 
I have two guys wanting the tuner - the first one has to run it by his wife, but I suspect he'll grab it and the second one is waiting in the wings just in case he doesn't take it.
 
You're #3  - LOL.

I have an Elecraft T1, QRP auto tuner,  that I'd like to see get a good home.  It will handle 20 watts (5 times normal QRP levels) with ease and it has latching relays to keep battery usage to a minimum. It will match a wide range of antenna configurations.  A special cable (optional) is available from Elecraft that integrates it with a Yaesu FT-817 and will operate using the FT-817's "Tune" button.
 
This one was built by me, tested with a 4SQRP SS40RX/TX and meets all Elecraft's specs.
 
Elecraft's price for the kit is $139.95 plus shipping.  I'm asking $130 for it, including shipping to anywhere in the U.S. (PayPal or USPS money order accepted).  I'd prefer not to ship it internationally due to the high cost of postage.
