My G5500 control box won't command the rotor left, but right works fine. No
voltage to the #4 connector when I press "left", but if I put some pressure
on the relay the voltage intermittently returns. So, guess the relay
contacts are dirty.
Looking at the schematic it looks like both the right and left relays are
the same, but use different connections. So. thinking I'll just remove and
the two and swap relays. (This unit has been in daily use since 2002!)
Are these relays available from Yaesu or someone in the US? Did a quick
Google and DigiKey search but didn't find them.
Just noticed there is a little lid on the top of the relay. When I popped
that open there is a lot of black residue on the inside of the lid and I
just might be able to clean the contact!

Just curious, why are so many of you on this board having problems with the
G5500?Looks like I will? make my own AZ/EL rotor with high torque stepper
motors and controlledeither with Arduino or Raspberry Pi.

Unless RS-44 is dead, which it appears to be. :-(
I'd finally gotten my station all set up for a contact today, and never
heard the beacon. Looking at the status page, I was not the only one.
(I was also thwarted on an AO-7 pass just a bit earlier due to it being
in mode A.. such is life.)

The Virtual Ham Expo is soliciting speakers for the next event in March of
2021. I presented at the one back in August and have signed up again. I
wanted to see if someone from AMSAT or Field Ops would like to join me as a
co-presenter. I would like to see if we can create a better than last year
presentation. Please let me know if you are interested.
The presentation part is pre-recorded so editing a video is a good way to go
beyond PowerPoint. There is also a Q&A session is live on Zoom. I had 130+
in the Q&A session back in August. Last year, I added a video of working
RS-44 from my Driveway. Other things could be done as well.
Also they do have an "Exhibit hall" which is a "Pay for your space" deal,
but perhaps AMSAT would like to buy a space and we could coordinate a group
of us to work the virtual table through the weekend. That would be a good
way to help bring personal interaction as is always the case for events like
Hamcation, Hamvention and Ham-Com. Now is the time to begin planning and
arranging, not 2 weeks before.
Let me know what you think and maybe we can investigate further.

Hi All!
Over the last couple of months I?ve been having a lot of fun with 3D
printing and design, working to make a 70cm parasitic Lindenblad that is
easy to manufacture and assemble. I?d like to share the design files with
the amateur community, inviting people to build and improve on this design.
This design heavily leverages the previous excellent work by Tony Monteiro
(AA2TX), who created and published the paper: ?A Parasitic Lindenblad
Antenna for 70cm? AMSAT Proceedings 2006. The AA2TX design uses a central
driven dipole surrounded by four tilted parasitic elements.
One of the biggest challenges to construct the AA2TX design is holding the
parasitic elements in the crazy geometry defined by a Lindenblad
configuration. The AA2TX design used irrigation parts, requiring careful
alignment by hand and tedious bonding operations. Today with the
availability of 3D printing it is possible to remove literally all the
critical alignments, designing these spacings and angles into the 3D
printed part!
Design files, pictures and construction notes can be found on Thingiverse
(search for my call sign K7ZOO). I welcome any ideas for improvement and
would really enjoy seeing the results of any construction efforts.
