500 Ohm 450 degree pot, for a G-5500.
Yaesu is the only option for that exact piece.
Not a standard item. I used a 1k, three turn pot. Using Goody's
rotator controller, analog reference enabled, 3.3V and a two
resistors, it worked just fine. Would not work with Yaesu's controller
box, period.
It would, however, work mechanically and provide a reasonable
reference, electrically.
Using a 540 degree pot in a 360 degree rotator (5500 pot in a 5400)
might present some problem. I.E. calibration issues with the control
box.

I have been inside several 5400s - there is a wire soldered to the wiper on
the pot. This wire twists as the pot turns. It is worth your while to make
sure the wire has not failed. I have seen that twice. If you replace the
wire make sure to use something with many strands.
I do not know if the 500 is the same.
Saved me replacing the pot...
73 and Good Luck!

I don't have a 5500 but my 5400 did the same thing. I ordered the
replacement 500 ohm pot from Yaesu in California. That was over 5 years ago
but it is worth a try. The pot needs to have the same stem length as the
original so it can be accessed via the hole in the back of the control box.
Here is the info I have on file for Yaesu parts. I hope it is still good.

Matt,
Thanks for your comments.

> Like Mike said, you don't have to spend $1000 to get started on linears.
There are plenty of used rigs to be had for cheap, like the ft-290, older
model 817s, etc. No, you probably can't go buy a brand new in the box linear
sat station for the same cost as a baofeng and arrow. But with a little bit
of hamfest and eBay hunting you can get on the air for much less than $1000.
Over the years, I suppose I could have saved up my dollars and bought
one of
the rigs that you mentioned (wasn't even acquainted with the FT-290). I am
one to tinker, though and I've always had pleasure in building and
learning.
Also, whatever I build, I can always repair. Don't think the same can be
said for a commercial rig. Anyway, that's the choice I have made.
> I'm not sure about cw being simpler to operate on sats, I find it kind of
difficult while operating portable at least. Too many things to do with not
enough hands! As long as people keep their power down though, it seems to
work fine as far as the transponder is concerned. I've heard just as many
QRO guys in SSB causing problems as I have on CW.
I'm not surewhether your are referring to something I said, or something
Mike
said. In my original post, I figured that while a CW-mode rig might be
less
expensive to field, other 'barriers' would arise.
> Your idea for a rig is interesting Mac, and might be worth exploring. I
just don't want anyone to think they have to go out and buy a brand new pair
of 817s or a 9100 to operate linears! If you've got an 817, 857, IC7000, or
similar all-in-wonder rig then you've already got what you need. Else, check
around for some older, used v/u rigs. You'd be surprised at the amount of
people who are on linears every day using setups just like I've described.
I understand what you are saying Matt. I'm truly curious,though, to see
how
low the cost of a rig can be driven. The use of DSB vs SSB in a possible
venue of really driving down the cost, while maintaining voice-mode
compatibility. The only downside is the doubling of bandwidth of the
channel
and the attendant lower power efficiency of DSB compared to SSB.

I've found that ham gear is probably the most user serviceable you can get
commercially.
When NJ7H was nearing the DP field in NWT my downlink 817 decided it would
quit receiving. After downloading the service manual and following the
schematic I found it to be a failed shift register that switches filters,
TX/RX, etc. Not having the time to get a new part I removed the IC,
installed a toggle switch and manually switched between VHF and UHF as I
needed. It's still this way, the Franken-817. I only paid $200 for it used
so I'll probably replace it before investing in a proper repair.
With a very modest amount of testing equipment and no EE degree I was still
able to repair a commercial rig all while under the pressure of missing some
grids that will probably never be on again. Most rewarding grids I've ever
picked up.

installed a toggle switch and manually switched between VHF and UHF as I
needed. It's still this way, the Franken-817. I only paid $200 for it used

A pair of 25'' 5.8ghz 29dBi Teletronics International dishes fell into my
lap this week and I'm trying to decide on some projects.
Here's a pic: https://i.imgur.com/W9oeVSv.jpg
I have a G5500 rotor from my previous ground station, and I'm thinking of
doing some solar radio astronomy or transponder chasing.
Without the covers, the dishes weigh 13.2lbs each. Could the G5500 safely
handle the load of one or two of these dishes? I'm not considering roof
mounting, and prefer to do things closer to the ground for the time being.
Via a SDRPlay, my highest receive capability is 2ghz. Short of changing the
feed, what might I do or be able to use to bring the frequency down to
something more manageable or will the dish still feed signals at lower
frequencies?
I'm not beyond changing the feed, or building transverters, but some
searching isn't producing more than commercial wifi applications.
Anyone have any plans, ideas, advice or direction to offer?
Thanks in advance!
Cheers,
Lou

Yes. It is a great program.
How is it working for you?
