Re: Tower Lighting

American operated/manufactured Duro-Test went out of business about 15 years ago. The name, IP, and other assets were bought by a Mexican company. They try to represent and produce the same product as the original Duro-Test and I am unclear where they're made or as to their success as I have not use...

Re: TV OTA antennas

But they're all still designed to go up to 698. What's available that's been redesigned for 470-608?

TV OTA antennas

Saw this thread on another list and am running into the same situation with couple clients who have OTA, but are concerned about the repack and reception matters. Their installations are marginal at present and they want to improve performance. Does anyone know of any new directional RX antenna desi...

Re: FM Antenna Tuning

That was a really informative read. Luckily, I have a HP8751 and HP directional coupler to effect the sweeps needed.

Re: FCC extends Phase 5 deadline

But only for the areas impacted by Doria.

Stations in areas not impacted by the hurricane still need to meet the deadline.

Re: Sample lines: curiosity question

Having done a few AM arrays from scratch myself, including the 2nd licensed MoM array in 2010, I vowed to never repeat the mistakes of others who cheaped out. Beyond the physical durability of direct burial rated line is ultimate reached phase stability over time and across various temperature range...

Re: Belar FMS-2 Meters

This isn't an analog generator. It's only AES/192Kbps output....er digital.

I like the concept however.

Re: Belar FMS-2 Meters

Before going nuts replacing costly meters, simply see if the zero adjustment works. It's entirely possible the spring tension changed and a simple adjustment is needed. And have you consulted Belar's tech support? Another thing to keep in mind is the monitor system has a zero (0%) adjustment and the...

Re: VOIP replacing analog

In a small multi-studio environment, go with the Telos VX Prime system. Sure it's costly. But you get what you pay for with the ability to route lines to studios and not have barge-in's like the old 1A2 or Direct systems. And the audio is really good. If calling in by SIP, it's audio is ISDN quality...

Re: Arrakis ARC-10 USB Noise

If you have an audio level meter, prove me wrong about the maximum output both voltage (bridging) and current (terminating). I suspect you will not see anything more than +12 however...if that. I'm seeing a lot of so-called professional USB sound cards which top out at +2(!!) due to the very fact th...

Re: RDS Question

Relaying the HD subchannel as an analog emission on a translator is permitted and it may originate RDS in that regards. But the content must also be present on the host/parent station. This is the rare instance other than the permitted one sponsorship per hour which the translator can "originate" co...

Re: RDS Question

Deep Thought is right. Except for the FSK legal ID, all items carried on the co-owned main emission must also appear unaltered on the translated signal of a co-owned translator. The only exception is a commercial translator not affiliated with the main station licensee where the translator owner may...

Re: Arrakis ARC-10 USB Noise

We looked at the Tascam products and found their low cost two-track units will not do more than +10 out as they use the PC's power supply or a wall wart. We've looked a lot of places and the Henry is the best thing going ...even at $500 for stereo I/O...for a professional studio. It's very quiet and...

Re: Omni FM with Parasitics?

Yes, for stations wanting uniform and balanced coverage both in azimuth and H/V distribution, adding "optimization" parasitic elements is common. Particularly with wide face towers. Several of my stations have them. It really makes a difference where the tower is centrally located in a given populat...

Re: Continental 816-R2 air chimney screws

My 816-R2A and forward had that deck plate as 1/8" (or maybe thinner) fiberglass. As I recall, none of the socket is attached to this plate. It's strictly an insulator and mounting deck for the chimney. Your's maybe an even earlier model as the one's I had (1984 vintage) and used a different materia...
