Wanted: Multimeter for Harris Exciter

For a THE-1, but the MS/MX 15 Multimeter appears to be the same. The "modulation" meter is not the same.
If you have a scrapped out unit and would consider selling the multimeter, let me know.

Re: Another Windcharger questionn

I've maintained several sites with 40's Winchargers. The galvanizing on those towers is incredible. It is pretty normal to see minimal corrosion. I have a complete set of drawings somewhere if you need them. There are two trouble areas with Winchargers- the bolts and the anchors. Over the years the ...

Re: KVM Suggestions

I have been happy with the NTI stuff. I have several in service, some over 10 years old, still operating just fine.

Re: Burk ARC-16 help

My victory was short-lived. One week in service and the PROM chip decided to annoy me by failing. Need a matched pair (same revision) to make the link work and a specific serial number to unlock Autopilot.. Since this firmware version is long obsolete and Burk no longer burns the chips, it's not rep...

Re: I THINK IT IS TRYING TO TELL ME SOMETHING

I had one site where the flat roof began to leak directly into the top of a CCA AM transmitter. Water ran across the tube compartment, down the side, behind the contractors and began to pool on the cabinet floor underneath the transformers Transmitter couldn't care less, just chugged along.

Re: Burk ARC-16 help

Just as a follow up to this, I did get the units talking to each other. It was a damaged microprocessor in the replacement transmitter site ARC-16. Swapped one in from another unit and everything worked! The original transmitter site ARC16 was pulsing the output relays on a 1 second cycle and had a ...

Re: Ecreso vs. BW for Translator

BW did not stock the power supplies ("we can't get those but we'll give you a discount on a new unit") when I had 2 failures. A Meanwell distributor did have them in stock. Since then I've had a fan controller failure (fixed by converting to 220VAC fans), an RF board failure (output device-easily av...

Re: Burk ARC-16 setup

I just finished doing this.....the autoload software just makes the job more difficult. Do the setup from the front panel: Hold both channel up/down buttons in while plugging the AC power in, then release. That gets you the setup menu. Set the unit to "Transmitter" then site ID "A" for standalone un...

Re: Transmission Lines, in the dark here

So the hood draws hot air out, does it have a fan attached? They way I build them, and TPT is likely similar, is to use a wide hood over the top of the transmitter, leaving a 10" or so gap between hood and transmitter. That gap is to keep downdrafts from air-starving the tube and from dumping the a...

Re: T'was like putting a beloved old dog to "sleep"

Can those be metered and controlled without the touchscreen/display? For transmitters on the 30 year replacement cycle, parts like that make me nervous.

Re: Burk ARC-16 help

Just to confirm, the tx readings are correct and follow the channel up and down buttons but you get no action from the remote relay commands while the local relay commands work normally? You got it. I don't have a single working Arc16 left in service Apparently neither do I. At this point it's a ba...

Re: Burk ARC-16 help

Yep... I have transmitter readings and status indicators on the studio display. I also have properly functioning raise/lower relays when I activate them using the transmitter site box. They just do not fire from the raise/lower buttons on the studio box. I talked to Burk...they think there is a fail...

Burk ARC-16 help

One of my stations uses a Burk ARC-16 remote control. This is a 2- box setup, Box "A" is at the transmitter site, box "D" is at the studio. They are connected by a telco loop. The Transmitter site Burk was damaged by lightning. Fossil fixed me up with a replacement (Thanks again!) I installed and pr...
