A friend asked me to repair/align his Yaesu FT-107M transciever.  The various boards in this rig are stacked onto a pair of motherboards, much like PC add-in cards.  Does anyone have access to the extender boards that are used to raise the boards out of the rig for adjustment and servicing?  If so, please email me directly at <my call sign> _at_ ARRL _dot_ net.  Thanks in advance!

MEM: "Some 20 years ago I was a General. I went to the testing station and took the Advanced and Extra class written tests, and the 20 WPM Morse test. I left there with a Extra class license. I had been a design Engineer for 30 years at the time. It helped a little, with understanding some of the concepts, but good test preparation was the key to passing the tests."
Maybe because it was "earned" it meant a bit more than the ticket does today?? Good point! (Pride in ownership.)

A B&W coil is a coil made by:

As I mentioned in another thread, B&W no longer sells to individuals.  Despite what the B&W website says, they are not listed as a manufacturer in the Ham Radio Outlet catalog.

You can also roll your own.

Probably your best bet.  There are how-to websites all over the interwebs.

Hi Cecil - I’d been thinking of moving the inductor up the wire to increase radiation resistance on 40m.  This calculator is helpful:
http://www.66pacific.com/calculators/coil-shortened-vertical-antenna-calculator.aspx

And with this design, mechanically it’s easy to do because the radiator either hangs from a tree branch or is supported by a fishing pole. 

I’ll give it a try.

Ok, thanks, got you now. Maybe some magic fingers not being Harry Potter has made something......

The other confusion comes as it appears this model was released with the S version having input of 250 watts PEP and Motorola output transistors.
Do have the service manual, got it last night. I am for a good adventure, here.
Cheers

Bill, how did you excite the HV diodes and capacitors when you bypassed the step start circuit?

...I just picked up an old Heathkit DX-60A. I going to give it new life with a custom DDS VFO and see if theres anyone on AM anymore.

I've always enjoyed the notion of AM, even though I never made many contacts using it.

My father had a dx-20 with external VFO and a bunch of Hallicrfters. I had an S38 on my  ight table.

I also remember a Gonset or 2 and a lot of lafayette stuff. We'd go there almost every week.

On a plane headed home.  Yes of course the HV in not connected during testing. The single connector is pulled so the shorting bar is out of the circuit. I will check R17 tonight..also tube pulled...I fix many Alphas however this one is a winner
