Re: Hmm, maybe you were the guys who sent us our parts to Kansas? :D

Well, when I started there, I worked in the Order Entry Dept. We did everything! I took parts orders, helped troubleshoot equipment, edited large orders from the salesmen. Each of us even did a solid week of after hours emergency response to off air stuff. I can recall shipping more than my share of...

Re: Harris PT-5 Module Repair

That's really sad. When I worked in the sales office in Quinky in 1965-1967, we were supporting stuff clear back into the late 1930's. In fact, not. bragging - of course - I helped a guy out on a very old AM 500 watt rig getting pars to get him back on the air. I made a comment of my age and the xmt...

Re: ND-25 Problem

Never worked on one myself, but a wild thought comes to mind.....is there a "FAIL SAFE CONNECTION" that mutes the rig when control path is lost"? If that opens, it might mute the RF.

The flashing lights, however could could indicate what Doc mentioned as a place to look.

Re: Oh those viewer calls...

One Saturday afternoon while working at a 50kw AM in Tulsa, I get a nice pleasant call from a fellow telling me he was getting our station in his hi-fi. I asked him where he lived and he told me. I asked him that when he looked out his window to tell me how many towers he saw. He replied ONE! I then...

Re: The Looming Engineering Age Crisis

Rich: Enjoyed your comments, But it ain't looming, it's here. Showing my age....my radio engineering career started in September of 1956, my first year in college. I have been stuck (my choice) in this position since then, except for the 4 years I dodged the draft board by enlisting in the Air Force...

Pat Higgins passes away

I just learned that Pat Higgins, founder/owner of Higgins Tower in Wisconsin has passed away. I don't have any other information at this time. Pat ran a very good operation and his son continues the tradition. He will be missed by many.

Re: Gates 5--no audio

Chuck..... Yup, sold that one too. Only one I ever recall being very troublesome was Rhinelander. Real jittery. Stopped in there to see the manager and he told me about troubles. Short answer to problems was that their engineer never tied the ATU to the ground system. Onl;y ground was on coax at the...

Re: Gates 5--no audio

RE the MW1 blowing diodes. Every MW1 I ran into that had issues related to lightning damage, AC power surges, etc was found to be poorly grounded/installed, or had a poor station ground. The only other area that I can think of is the ATU. Always have a static drain choke installed. In addition to th...

Re: Gates 5--no audio

I was hoping than nobody would ask that question.....becuz I forgot what it was called. Having a Fossil moment here. (actually it was kinda rattling around in the noggin along with the rest of the debris) I did have to look it up. It was called "PROGRESSIVE SERIES MODULATION. And that....is "the res...

Re: POLYPHASE PDM

I would like to enter a comment regarding the invention date of the Harris Polyphase PDM modulation technique. While the patent documents date it at 1984, the actual invention and implementation preceded that date by quite a bit. The Harris SX series was introduced like in 1980-ish. It was a Polypha...

Re: AM Digital NPRM

I have stayed in the background on this as I have a rather O.F. opinion , and will more than likely stir up some comments. I think this is going to follow the same path as the old AM Stereo stuff. As that famous cartoon character so eloquently puts it...."Phhhhhhhtttttttt"!!! However, in order not t...
