Re: Schematic Needed

I bought a couple of those old VHF GE monitor receivers a year or two ago and they work good but now crystals are getting harder to source so was hoping that someone had found a more modern replacement.

Gorman-Redlich still make NWS receivers? And can you still buy replacement dial cord? I used to have a spool of it.
Now that you mention it, I just saw an ad for his NWS RX in one of the trade mags...

Re: Schematic Needed

With the demise of Dayton and now Hamtronics... Does anyone know of a source for good reasonably priced fixed tuned FM & WX receivers? The Inovonics receivers are wonderful but are far, far out of the price range of most of my clients. I have been using Rolls FM rx's and scanners for the last few in...

Re: Translator Question...

I am going to go out on a limb and say that IF, IF your main 5kw AM tx pukes up a FET ball and it takes a week to return it to full power, the FCC nor anyone else is going to care if you leave your xlator running WFO while the main AM tx limps along at 500w. However, IF you decide to save on the rep...

The conductivity in Tennessee is so awful that it may take a bunch of transmitter power to get the 2 mV/m out to the translator 60 dBu.
And especially East TN. Localized .5 conductivities are not uncommon.

Re: Audio Bandwidth of an AM Broadcast Station

Richard,

As I have found over the years, a lot of AM stations suffer from either horribly equalized telco program lines and/or horribly mis-tuned antenna tuning & phasing equipment. A lot of the "Hispanic Tee" networks are tuned as a narrow filter with the correct impedance conversion...

Re: CBRE Cert Exam Question

Now the only "certification" I worry about is being "certifiably insane" for trying to own radio stations in the era of mega-groups. When asked if I am interested in owning or being a partner in a radio station (happens regularly), I tell people that I haven't reached that particular level of insan...

Re: OPIF Health

I received a call this afternoon from the FCC telling me that the OPIF site was repaired and working. The nice lady did comment that heavy server traffic would be a problem for the next few weeks but that the scrambled up/down loads had been corrected.

Good luck,

Re: Connector suppliers....

The cable is AVA5-50FX. According to the Commscope website, this cable is not available in the US and Canada, but it showed up at my project several years ago. As I recall AVA5-50 is a hollow center conductor anyway. Was the FX foam filled version center conductor even thinner than the normal AVA? ...

Re: Connector suppliers....

I believe that the OP may be looking more for interseries and intersize adapters than coaxial connectors. I keep an eye on Ebay as various EIA size to size and EIA to N adapters occasionally show up at very attractive prices. I have one of those kits of "make our own interseries adapters" that has p...

Re: Connector suppliers....

Beware of the new Andrew cable - the copper sheath is very thin and you have to be extra careful that you don't cut through it when installing grounding kits. The center conductor is also thin and filled with foam to try to make up for the fragility of the conductors. I would stay away from it. Ain...

Re: OPIF Health

I just called the help desk again and the call was actually answered by a live person. She advised the same thing that I was told last week... "We are aware of the problem and it is being worked on. We have no time frame for repair. Try back occasionally". The upload, download, blank page, missing f...

Re: OPIF Health

The FCC has announced that it will remain open for business at least through Friday. Apparently it has funding available to operate until then, if the rest of the government can't get its panties untwisted. Whether or not they make it a priority to fix OPIF, who knows. Thanks. I will try the help d...

OPIF Health

Does anyone know for sure if the OPIF system has been repaired and working? Last week it was reported that numerous people were receiving errors when uploading docs and the FCC help desk was aware of and working on it. Now with the guberment shut down, I am betting that unless it got fixed Friday, i...
