A $300 TS-940S

[W3WN]

So I get a call from W3WH on Saturday (in the midst of the family reunion, of course). Amongst other things, he tells me that a local-to-him ham in Washington PA was in the midst of selling off some equipment.

Did I think that KB3ERQ would like a TS-940S? With filters, speaker, PS, etc... for $300?

Long & short of it, I got them talking, and Ben took the radio home on Sunday (yea!)

He should be putting in on the air shortly. At the moment, his only HF antenna is a 10 meter Ringo, but that's a start...

Make darn sure the PSU and PA cooling fans are clean, turn freely...then place a drop of 3-in-1 or similar light lubricating oil into their lubrication points as noted in the Kenwood service manual.

Else you're going to be looking at an impressive paperweight in the future. The pass transistors are being run close to their maximum ratings as-is in that design and if the airflow is choked off they'll overheat and fail - taking lots of unobtanium things with them.

I've got friends who love those rigs, and they are nice. Those who love 'em, stock "boneyard" parts for them.

The TS-850 is approaching that status. Still don't want to sell mine, but... :chin:

I have an 830S, a 930S, but no 940S yet. Someday.....And that is about the price I want to pay for one!

Ben's been monitoring the forums... although I don't think he's posted yet. Still, I'll make sure he's aware of this.

You need a '530SP before the '940. They're a little rare.

And a TS-830M (yes, 'M'). AM transceive included for the Euro market.

I'll tell you something about 3 in 1 oil, Fred. Unless the formulation has changed over the years, with time and temperature, it tends to leave a gummy, varnish like residue. And that really plays hell with fan bearings and other moving parts. For quite some time, I've been using a very good quality synthetic clock oil that lasts a long, long time, and doesn't break down with heat. I've also used it in commercial applications with equipment in some very harsh environments without any issues. The stuff isn't very expensive (well, it is more than 3n1) and a little goes a long way. I just apply it with a small syringe/needle I get at the vet supply. Like I said, it might be that 3n1 has changed it's formulation, but back when I use to work on sewing machines, that stuff really played hell on the bearings and races. Just an FYI

Lithium grease? Aerosol type. Dismount the fans to apply.

Helps with the fan's depression as well.

Interesting, Eddie. Have a link to the product you're talking about?
