The new EEPROM board is a great idea.Originally Posted by kc4umo
I don't know what ICOM was thinking when they chose to place configuration information in volatile ram.
I'm about half way done with the alignment, taking my time.

Battery replacement and reprogram = $$$Originally Posted by AF6LJ
Pretty simple equation, actually.

The front-end RF amplifier MOSFETs used in those rigs are notorious for going out if subject to overload or high static.Originally Posted by kc4umo

If you cannot find one of those FETs, I have a few...

Yeah it amazes me why icom did that, as John said $$$$$$
I may have to take you you on on the FET's. I do not have any. But I have yet to put a tuning stick in the rig yet. Could just be out of alignment or maybe not.
One of my old mentors told me years ago " Do not tune anything until you have it fixed". That sort of stuck with me over the years and may have saved some money. A guy brought in a 726 a few weeks ago and could not get any RX on 2 meters. The first thing he did was start tuning. Then replaced parts. Then tuned some more. replaced more parts. He replaced the correct part to start with. It was just to the point of being out of tune. Cant beat shot gunning.

Got no time at all to play with the Yaesu tonight.
Had to costumers walk in wanting some equipment looked at.
And I am not even open to the public on Monday nights. LOL
Mondays are to work on the back log.
Ended up working on an 101EE and a Heathkit tuner.
Oh well. Maybe Friday.

Well, Got up at 3am this morning. Could not sleep.
Went out to the shack to play with a few things. Put the F on the work bench and removed the covers. I did find out that the bias pot does control output power. I can vary the power from 0 to 4 watts just by turning the bias control. So now tonight I am going to take some voltage measurments in the PA and check for burnt or open resistors. I feel like this one is going to be simple.
Got to find me another high voltage volt meter. My B&K VTVM bit the dust. Now I am limited to 1000 volts.

I'll put a nickle on a blown component in the screen PA supply.

That, or the driver-to-PA coupling cap which always seems to fail...Originally Posted by AF6LJ

One of these days I'll have to pick up one of those.
That would be a fun project.
Good suggestions guy's.
Was there a problem also with the cathode resistors in these rigs?
Seems I read that somewhere.
