Re: Renewal season

My apologies for resurrecting an old discussion but... How early is too early to file for renewal? A local LPFM expires in August. They know their renewal is due by April 1st, and would really prefer not to challenge that deadline -- but they don't want to be ridiculous about it. I see one LPFM here...

Re: Oh those viewer calls...

Ouch. Sure didn't want that image placed in my brain. OK, my entry. Big honking sporadic-E opening in progress. Woman calls Engineering at our station, on analog channel 3. Asks for the phone number of the Madison, Wis. FCC office. (no, there isn't one) This is pre-Internet so I tell her I'm going t...

Re: The Looming Engineering Age Crisis

What do you all think the chances are the FCC will, in the next 3-5 years, allow AM stations to silence the AM signal & operate only on the translator(s)?

Re: The Looming Engineering Age Crisis

Also, I’m primarily speaking to radio’s issues, not TV’s. TV's issues are pretty much similar. I think we're following radio's lead, just maybe 10-15 years behind. I think we're going to continue to see staff engineers in TV, but I can envision a station having only one, one with only IT experience...

Emitor Satlook Color HD spectrum analyzer?

Anyone have any experience with this? Solid Signal seems to also be selling it under their own nameplate. We're looking for something for peaking & cross-polling satellite feeds. Needs to replace an Avcom PSA-45D with a missing power supply... Looking at the PDF manual it looks like it'll do the tri...

Re: AM Digital NPRM

What happened to the FCC ruling a while back that all radios had to have AM capabilities simular to TVs had to get UHF? That's a pretty common urban myth:) The FCC doesn't believe it has the power to require radio receivers to include AM. The All-Channel Receiver Act explicitly cites television. .....

My experience with WWFD was that capture was pretty quick. Roughly half to a third the time of a hybrid-mode station.

Re: AM Digital NPRM

FWIW I just returned from a few days in Northern Virginia. Since my travel companion has little tolerance for radio experimentation I didn't have much time for these tests but... Using the HD Radio in a 2013 Toyota Prius, and all tests daytime... - WWFD was decoding about 50% of the time at a point ...

Re: AM Digital NPRM

What people are saying in the DX community is there is probably a limited cohort of stations interested in all-digital. The really big stations (the KFABs and WBALs and KNBRs) have enough AM audience left that they're not willing to toss most of them out by going all-digital. The really small statio...

Sample lines: curiosity question

So, I'm a TV guy & probably missing something dumb here but... Why do AM sample lines use such heavy-duty cable? I see discussion in the current thread of using LDF4-50, which is not exactly cheap:) Surely there isn't enough power in the sample lines to require anything that large? Wouldn't somethin...

Re: Definition of a heartstopper

Every quarter, one of our local Chevy dealers runs 30-second spots that are silent...black background with supers that slowly fade in and out. They get my attention! :D Uggh. We had a local advertiser do that a year or two ago. Drove us batty: the silence sensor would go off every other break... We...

Re: Proposal XML

XML is a rather broad standard. Saying "we need this order submitted in XML format" without elaborating is kinda like saying "I want to buy a transmitter" without specifying whether you mean 50kw AM, 100 watt FM, or ATSC 3.0 TV. There seem to be some possibly relevant XML definitions on this page at...
