As both my KR400 controllers have blown bulbs I've modified them to use
LEDs as per https://bit.ly/2TzeHud There is however a small difference
that I'd like an opinion on as I'm not very electronically minded.
Eddie modified his KR-400RC however on my KR-400 controllers there is an
additional 100R between the transformer and bulb. What is its purpose
and should I leave it in or remove it when adding the diode, limiting
resistor and LEDs shown in the mod?

On the "Satellite Tracking" window, please click the "Satellites" menu at
the top.
In the "Name" box, scroll down to the satellite you're working with. Make
sure that the RX & TX frequencies there are fully spelled out in Hz (no
decimals!)
Click Add/Modify so that any changes you make become the active settings
for that satellite.
Back on the main "Satellite Tracking" window, check the box for "Use
OmniRig". Then click the "UP + DN" button.
When I follow those steps, my FT-857 is automatically put into SPLIT mode
with one VFO tracking the uplink freq and the other tracking the downlink
freq specified in PSTRotator.
(FYI, I always manually check on the FT-857's menus to verify that the VFO
being used for transmit has the CTCSS enabled and at the correct frequency
--- I don't depend on PSTRotator to set that automatically. In other
words, I let PSTRotator change the up & down freqs but I still manually set
everything else such as CTCSS, power, mode, etc.)

Paul,
It appears that one unit uses 28V to? light the bulb & the other uses 14V.
If the mod is for the unit that is 14V, leave the resistor in the circuit.

I currently am operating U/V with great success....Need opinions as to the
best way to get started using L Band Uplink (ie: AO-92) and other sats
later......antennas and transverters, perhaps.....
Tnx

Hi!
Twice this weekend, AO-92 failed to stay in L/V mode for
24 hours. When it was first commanded into L/V mode at
0138 UTC Sunday (Saturday evening in the USA):
https://twitter.com/AMSAT/status/1081727139974729729
it only stayed in that mode for about 3 hours. By the time
AO-92 passed over the USA around 0450 UTC, it had switched
back to U/V mode.
Mark N8MH reported on Twitter this morning that AO-92 was
put back into L/V mode at 1449 UTC:
https://twitter.com/N8MH/status/1081938639930691584
and it was back to U/V this evening at 0248 UTC:
https://twitter.com/WD9EWK/status/1082107763809873920
Before this weekend, I think there was one previous
occasion where AO-92 didn't remain in L/V mode for the
full 24 hours. Has something happened to the satellite,
where the mode change won't remain in effect for 24
hours?
73!

Hi Patrick,
As you know, the spacecraft computers reset from time to time, usually due
to radiation. Sometimes we go weeks between resets, sometimes seconds.
This weekend both AO-91 and AO-92 had two resets each, with both coming back
up in mode U/v.

Alan,
Thanks for the reply. Two resets in the weekend...
hmmm... it seemed like a reset may have happened earlier
tonight, since the uptime in the screenshot I tweeted
wasn't very long. I didn't make a note of what it was
last night.

Thanks George, I tried it with and without the resistor and couldn't see
any difference with the LEDs so wondered if it was just put in to
increase the life of the bulb. I'll leave them in and see how we go.
The controllers now look like this adding a splash of colour to the
shack. http://www.ukdx.org.uk/tv/rotator/400s.jpg

Content-Type: text/plain; charset=utf-8
I have an FT-736R and have just purchased MacDoppler from AMSAT. It will be
installed in a MacBook running OS 10.13.6.
I?m shopping for a CAT cable to go between the two units. The guy at HRO
said the original Yaesu cable to go with Macs has part# FIF-65A but I don?t
see anything yet on Google by that moniker. He also said the Yaesu CAT
cable for PCs is FIF-232C - which I DO see around.
Then I see a caution that there are lots of cheap cables around that use
terrible chips that are a nightmare to keep running. The only cable I?ve
found so far (on eBay) is $35 and the vendor doesn?t seem to admit which
chip set is used. Amazon in the UK has a cable for sale for 16 GBP, which
could be one of the cheaper ones.
Immediate questions:
1. What subset of the alleged plethora of available cables is MacDoppler
compatible with CAT on the FT-736R?
2. Who sells such cables nowadays? So far I?ve found only eBay and Amazon;
it?s not even clear they?re selling the same cable - never mind the one I
must use...

I would suggest waiting until you can hook-up the scanner.? This is
