Re: Stationmaster type antenna available, 152 MHz., Nashville, TN
The reason I contacted Commander was because I was concerned with the lowest VSWR at 427MHz for a 449MHz stamped antenna which I picked up second hand. They were able to look up info from my antenna S/N and they said 427MHz was about right for the 6deg or so downtilt that was ordered for this antenna and the original owner said it was purchased for a 6,000ft site with 6deg of downtilt. Commander said older antennas were basically tuned lower in frequency for downtilt with more downtilt pushing the resonant frequency lower and you would just have to live with the higher VSWR, especially with more than 4deg and I trust what the antenna mfr is claiming. Later?and current antennas with downtilt have a better VSWR due to some design changes they made but they didn’t say what those changes were.?
?
It could be that exposed dipole arrays might have the phasing harness tuned to a higher freq, but I don’t know.?

Re: Recording repeater audio
I use a registered version or Recall, and have been doing that since 1996 (and still have all the audio files, so almost 30 years now).? I don't save to the cloud though, but easily could serve them up with some code.
It's run on all windows NT through Win 11.? So by experience, that would be my recommendation.

Re: Stationmaster type antenna available, 152 MHz., Nashville, TN
I think the engineer said it backwards and is wrong, because to make electrical down-tilt, you cut each collinear element shorter (a higher frequency), to obtain down-tilt.? For an example see this article by Kevin Custer. ?
?
You will also raise the SWR.?? I think an antenna exactly cut for 152 would be great for 146 with down-tilt.?

Re: Motorola GM300/Maxtrac rear rx pin not passing audio
Except he said the COS is still active and working fine.?? That would indicate at a distance the radio still works.?? But I agree, if he misstated, that's the most likely suspect.?? It's better to get a junker at a hamfest (and cheaper).?? I found some for $1 each with bad PA's? :)

I believe many people, myself included, merely jumper across the power switch when it goes bad. It's a repeater so it's always on anyway...

Re: PD526 Duplexer Tuning
I have a local friend with access to much better test equipment than I have access to. I'm trying to see if he will tweak it the rest of the way for me. I got it in the ballpark so maybe he can finish it up.
> 1 - When measuring return loss (match), the RL value will be at least
> twice as much as the loss value of the pad.?
That's correct in theory, but a problem one would likely run into in the real world is that most run-of-the-mill pads aren't exactly 50 ohms.? The result of putting the pad in line is that your S11 may look better or may look worse, or may shift it in frequency due to the cascaded mismatches.? It's a crap shoot unless you characterize the pad separately and "do the math", or include the pad in the calibration which is generally a bad idea because it only degrades the accuracy in the same way as would adding adapters or using ratty test cables.
No pads should ever be needed or used with a VNA when measuring passive devices.

I've had issues with dirty power switches over time on these units. You might try a can of deoxit or contact cleaner in the actual power switch. You could probably confirm this is the problem by wiggling or fiddling with it when its in the failure mode and see if it blinks on/off.

Re: Stationmaster type antenna available, 152 MHz., Nashville, TN
If the Stationmaster is cut for a higher frequency you will have uptilt. I had a long conversation with an engineer at Commander Technologies about this and they cut the antenna for a lower frequency to impart downtilt. I have a SuperStationmaster originally ordered for 449.35MHz with about 6 deg of downtilt and its factory tuned to 427MHz where it main lobe is at the horizon.?

Hammond Mfg. of Guelph Ontario make several versions of rack mount
power bars.? They would be available through the regular

Fred Hammond? VE3HC? (SK) was the inventor of the power bar
!
He told me that several years ago.? Their power bars
are excellent quality not like the junk that is often for sale.
I recently saw a Hammond power bar in a local hospital. (Hospital

Re: Stationmaster type antenna available, 152 MHz., Nashville, TN
Hey Robin,
Did you measure RL without the correct radials? (That could make a difference).
Also, might still be useful at 147, as being lower in frequency, you will get some downtilt.
Andy
I have what appears to be a Stationmaster type VHF antenna available. It shows a -20dB return loss at 152 MHz., so it's not cut for the ham band. The return loss at 146 MHz. is only~ -6dB. The extrior of the fiberglass is obvisouly weathered along the entire 23' length but not "feathered". I'd want to apply a new outer coat of protective paint or resin before putting it into service. Other than that, it seems to be in good mechanical condition. I think I have the radials for it somewere in my stash of too much stuff.
I don't know if it can be modified for ham radio use or if someone on the list would have a use for it as is. Open to offers; would rather it go to somone who can use it than scrap it for the copper and brass. It's near Nashville, TN.
Please email me directly, I don't read the list traffic. I'm good on QRZ.
