Searching for AUX-7 boards…


 

I am in the hunt for two AUX-7 boards, for my TR7 and R7. Please help if you are able…

Best 73,

You will pay a premium price for a genuine AUX-7. A workable substitute that gives you WARC and VLF coverage is what I call the "FAUX-7" board available from Far Circuits. It is a reproduction of a diode matrix AUX-7 replacement published in QST July 1982. You buy the bare board from them and you supply the diodes and connectors. There is also an article I think on wb4hfn.com on building your own AUX-7 board. Neither of these includes the provision for a fixed frequency crystal, but in all my travels I have only seen almost one person who used this.

Thanks, Jim

?????????? I had a feeling this would not be easy. I do see, however, that Nationwide sells crystal “packs”. Of course, that’s the easy part, eh?

The aux 7 from Fair Radio is the way to go..? the rest of parts you can get from Mouser or other supply houses.i have used about 10 of these with no issues.

Unfortunately, I don’t believe I possess the required building skills. I’m going to ask the individual working on my 7-line equipment.

There nothing at all complex to building the FAUX-7 Far Circuits board. Stuff a bunch of common diodes and some connectors onto a circuit board. Solder. Done.

Compared to street price for 2x genuine AUX-7 plus diode modules for the bands of interest you will save a bunch of money.

I have a bag of the Molex edge connectors used in the TR-7/R7 if anyone is interested. Looks like Mouser no longer carries them.

Yes, they do still carry them under different part numbers. Look for Molex KK series 156. Here is one example:

Actually, I would need enough to populate 2 boards. I'm not sure how many the boards take.

According to the QST article, 24 pins. Two 10-pin and one 4-pin were called out, but other combinations have been used.

Another note on the QST article, you don't actually need the 100K resistors if you have the (most common) early Digital Control board. They duplicate resistors on that board.

I think David made a typo.

Go here

The board you are looking for is this one.? According to the price list, the board is $6 plus shipping.

QST Jul82

WARC AND LF ON THE TR-7


If you are an ARRL member, you can search the archives and download the July 82 QST article.?
