Yes, having just had a nightmare week of S band downlink, I am curious
as to how 20% is calculated!
If its 20% of the overall pass of the bird then you are doing very well
methinks!

My assumption was that 20% of the antenna worked, and therefore removing the
80% that doen't work will leave him with a
perfect 100% working antenna.

If I had followed that logic last week then the 20% that was left would
have been an N connector!

Good after noon/evening. Or morning if you live in that part of the world
Question
Does any one have audio of the S050 pass this morning at 1409 UTC? Till about
1425 or 1430
The contact I am looking for happend around 1416-1417
I think it was KD?CES he returned my call about then
I am just trying to find out who it was and what I sounded like on the
downlink
Oh I did have my minidv recording at the time, but the audio is weak
And I was on my TH-D7ag with just the rubber duckie antenna
He (or someone close to that call) returned my call but
I just want to verify it
Thanks,
LeRoy, KD8BXP

After multiple 2.4Ghz antenna tested this wifi yagi outperform anything tested
before you can have the specs on
www.cushcraft.com and look for the PC2415N It is not cheap but watch e-bay
there is a lot at an affordable price.
I can send you the specs directly if you want to have it.

Andrew and group,
Read this post and others about the 5500, and I am trying to figure out what
do with my rotor or my controller.
My rotor has become more and more intermittent over time, so I opened up my
cables and put molex connectors in line so I can debug. I started with
impedance of the rotor. My Elevation is working now and my rotation is not.
I pulled out the schematic and see that the rotor motor is on 4-5-6 with the
common on 6 each and the up/down or left/right on 4-5. I measured the
impedance of 4 & 5 against 6, and the Ele was near 2-3 ohms and the Ele was
open. I am wondering if this is an intermittent internal limit switch?
Taking my rotor apart is a huge deal, so I want to be sure I am looking at
this situation correctly and what else should I be looking for or measuring?

Hi Drew,
At least you got 3 years out of yours. I had my G-500 a month before the
motor went out and had to send it to Yaesu.
Everything was balance as well. What I think happened is one of the
buttons on the control box got stuck in one direction and caused the
motor to burn up.
What I did was change the fuse that Yaesu uses from a 2 amp AGC to a 1
amp slow blow fuse. Just in case this happens again, at least the fuse
will blow before causing the motor to go out.

Ok, sorry for the additional post, this is a follow up. After my debugging
session today, I am fast-forwarding to what I expect will be the ending to
this little fairy tail, that is, I see me climbing up and pulling down this
damn rotor to either replace or repair.
So, next natural question is, if I am going to repair, what should I repair
while I have it open or are there people who do a good job in rebuilding
Yaesu rotors, roughly 5 years old??

"and the Ele was near 2-3 ohms and the Ele was open."
Michael I believe you have a typo and mean the AZ was open?
I have not followed this entire thread so I don't specifically know what the
"intermittent" part means. Random failures regardless of the position of
the rotator or failures at nearly the same rotator position?
Before bringing down the rotators, reseat the connectors at the rotator and
inspect for corrosion on the contacts. Also while you are up at the
rotators check your loop of cables that they are not stressed as they coil
and uncoil during rotation and are not putting strain on the connectors.
You can also open and inspect the connector.
This is not a solution for your issues but rather just some observations.
The beauty of the G5500 is that both EL and AZ rotators have limit switches
and the phasing capacitors are in each rotator. So you can swap the cables
at the controller from AZ to EL to see if the problem moves with the cables.
If it does not, then the issue would be within the controller.
If you swapping the connectors at the rotators and see if the problem move
to the other rotator it would indicate cable or connector ( male ) problems.
For those with the G5400 life is more complicated as the capacitor for the
AZ rotator is in the rotator but the EL capacitor is in the controller box.
Worse, the EL is the only one with limit switches ( AZ has thermal overload
) and neither of the rotators have that nice quick connector but rather the
terminal strip. Ya, and it goes 450 degrees AZ instead of 360. So you CAN
NOT SWAP cables to trouble shoot a GB5400B combo!

I'd rather not repeat this procedure in a few weeks. I also expect longer

Thanks Alan,
Stan, W1LE just e-mailed me direct, but will share with the group as well
some additional corrections... and, there is no thread to follow, this is
the first post...
My gut suspicion is that there is a damaged or intermittent limit switch
and/or position wiper. But I forgot I could swap the connectors at the
rotor and I will try this, great idea, just in case the cable got torqued in
the storms. A few observations,
1.) Controller: I opened the wires and put molex so I can detach and debug
easily. Controller appears fine. Using the molex approach, I switched Azi
and Ele and the symptoms moved. The meter indicator is not intermittent.
The Azi, it is at 0, no motion. Ele works fine.
2.) Rotor: I have the rotor up on top of the chimney and then another 12
feet higher because of high trees all over and to clear the chimney itself.
A superficial inspection yields little.
On Ele: impedance from 4 or 5 to 6 both 2-3 ohms including 120 feet of
cable, impressive. From 1-3 508 ohms and 2-3 504 ohms and 1-2 4 ohms
On Azi: impedance from 4 or 5 to 6 both open. From 1-3 368 ohms and 2-3, 0
ohms and 1-2 367ohms

"and the Ele was near 2-3 ohms and the Ele was open."
Michael I believe you have a typo and mean the AZ was open?
I have not followed this entire thread so I don't specifically know what the
"intermittent" part means. Random failures regardless of the position of
the rotator or failures at nearly the same rotator position?
Before bringing down the rotators, reseat the connectors at the rotator and
inspect for corrosion on the contacts. Also while you are up at the
rotators check your loop of cables that they are not stressed as they coil
and uncoil during rotation and are not putting strain on the connectors.
You can also open and inspect the connector.
This is not a solution for your issues but rather just some observations.
The beauty of the G5500 is that both EL and AZ rotators have limit switches
and the phasing capacitors are in each rotator. So you can swap the cables
at the controller from AZ to EL to see if the problem moves with the cables.
If it does not, then the issue would be within the controller.
If you swapping the connectors at the rotators and see if the problem move
to the other rotator it would indicate cable or connector ( male ) problems.
For those with the G5400 life is more complicated as the capacitor for the
AZ rotator is in the rotator but the EL capacitor is in the controller box.
Worse, the EL is the only one with limit switches ( AZ has thermal overload
) and neither of the rotators have that nice quick connector but rather the
terminal strip. Ya, and it goes 450 degrees AZ instead of 360. So you CAN
NOT SWAP cables to trouble shoot a GB5400B combo!

Ok, sorry for the additional post, this is a follow up. After my debugging
session today, I am fast-forwarding to what I expect will be the ending to
this little fairy tail, that is, I see me climbing up and pulling down this
damn rotor to either replace or repair.
So, next natural question is, if I am going to repair, what should I repair
while I have it open or are there people who do a good job in rebuilding
Yaesu rotors, roughly 5 years old??

Subject: [amsat-bb] G-5500 rotor motor intermittent
Andrew and group,
Read this post and others about the 5500, and I am trying to figure out what
do with my rotor or my controller.
My rotor has become more and more intermittent over time, so I opened up my
cables and put molex connectors in line so I can debug. I started with
impedance of the rotor. My Elevation is working now and my rotation is not.
I pulled out the schematic and see that the rotor motor is on 4-5-6 with the
common on 6 each and the up/down or left/right on 4-5. I measured the
impedance of 4 & 5 against 6, and the Ele was near 2-3 ohms and the Ele was
open. I am wondering if this is an intermittent internal limit switch?
Taking my rotor apart is a huge deal, so I want to be sure I am looking at
this situation correctly and what else should I be looking for or measuring?

Hi Drew,
At least you got 3 years out of yours. I had my G-500 a month before the
motor went out and had to send it to Yaesu.
Everything was balance as well. What I think happened is one of the buttons
on the control box got stuck in one direction and caused the motor to burn
up.
What I did was change the fuse that Yaesu uses from a 2 amp AGC to a 1 amp
slow blow fuse. Just in case this happens again, at least the fuse will blow
before causing the motor to go out.

I'd rather not repeat this procedure in a few weeks. I also expect longer
service from a 3 yr old rotor that cost almost $600. The inside was dry, and
well greased. I don't think it's overloaded either, with a M2 436cp30,
Cushcraft 10x10 2m, and 3ft S band dish near the center, all well balanced.

I believe FO-29 is operating continuously in Mode V/u analog at present.

It appears to be in its "normal" mode as Drew said. I was just listening to it
about 2130 PDST, and there was quite a bit of activity. Unfortunately my own
uplink is clobbering my downlink and I didn't have any success in making any
contacts. I'm going to try the "duplexer trick" Sunday morning to see if it
helps with the desense problems I'm having.
Using two M2 eggbeaters with SSB USA preamps, and they're only about 8 feet
apart.
