Re: 8-Tracks Only

KHOI-FM, an eclectic Class-A station a half-hour north of me in Story City, IA...easily heard in nearby Ames. The full episode may be on Youtube.

Gotta love the matchbook azimuth adjusters...doing it old-school!

Re: CSP phasor controller

Those paralleled resistors in the middle of the cabinet sure look like hell, too.

Re: CSP phasor controller

On the 50-year-old Multronics controller I care for, 120VAC is used for position status. If I recall correctly, the interlock relay closes only when 120V is returned from the contactors at the towers and in the phasor. I wonder if some failure is pulling down the status voltage in day mode. Are the ...

Re: GATES AIR FULL DOCUMENTATION LOCATION

Walter gave me the login credentials a few years ago. I don't know if they were intended for wide distribution. PM me and I'll pass it along.

Re: Harris THE-1 stereo Pilot issue

Not familiar with the David, but check to see what control (pot or software) is used to control pilot injection level. Been bit by that before.

Re: RX1290 decoder failure

RX1290s have been out of production for some time now; bad capacitors would be my initial suspicion. On the other hand, 1290s are newer than the initial surge of RoHS equipment, so they probably aren't falling victim to the tin whisker failures from lead-free solder. (Nearly all of our original Ter...

Re: ADC Punch Block Tool

screw terminals (I forget what you call them) that accept your audio cabling and plug into a marching male connector with a row of pins which mounts The Phoenix connectors. Why the EasyCrap box can't use XLRs is one of the most annoying features of that box. I have made my clients aware of the Sage...

Re: Harris HT5 IPA replacement

Those transmitters are known to have problems with the RG213 jumpers between the IPA and PA. They would crack and short out or go intermittent. Harris had a issued service bulletin and sold a kit of replacement jumpers. Might want to check that out. As well as the RG58(ish) exciter to IPA. I have h...

Re: ADC Punch Block Tool

I have never used one in a broadcast facility.” Heh. Young whippersnapper! I participated in a major studio buildout in 1995-96. We used patch bays extensively. Not my design, though. I was kind of surprised but ok with it since we were so used to operating that way. In the end we didn’t use them n...

Re: Orban Optimod 9300/9400

It's kinda funny...15 years ago music had all but disappeared from the AM dial.

Now, there's all sorts of music on AM again thanks to translators.

Thanks, Jeff!

Our cameras aren't on the list, but it's good to know, just in case our cameras should have been.

Re: NBC Namedropper Trigger Configuration / METAR server

For those of you who have been missing the temperature on the Today Show graphics since last week: the current known working METAR IP address is now 140.90.101.79 . It's changed several times over the last few months, and Evertz got me this latest address this morning -- and both of our Namedropper...

Re: Wind Farm

Define "very close". If they are more than several dozen wavelengths from the antenna I doubt you'll notice anything. At STL frequencies they become a fairly effective reflector so the 950 MHz anecdote doesn't surprise me. Still haven't heard from the owners, so I don't know how close very close is.
