Re: Sony BVH-2000PS. Missing TBC Card

Having said that, you're absolutely right: you need to have a good digital meter, four-trace scope, alignment tape, extender board, and the special weights and jigs ... I had forgotten how much it took - I have been out of TV engineering for nearly twenty years. I decided that I preferred radio eng...

Re: Sony BVH-2000PS. Missing TBC Card

How long have you had the machine? Have the colors always flickered since you got it? It could simply be that it needs alignment. That is not a procedure that I would recommend for the inexperienced or those without proper instrumentation and tools. More than 20 years ago I was CE of a TV station wi...

Unless you are looking at an Armstrong or Energy Onxy. in that case get the damned Gates.
I'll second that. If you buy a cheap transmitter you get a cheap transmitter - it isn't worth buying anything new that may give you frequent trouble.

Re: OMB Exciter EM 50

There are a number of medium power dummy loads available as pulls from cellular phone service. If you know any TV CEs in your area check with them. I was given a no longer needed reject load by a UHF CE after they converted to digital. It is a Bird 8201 Termaline, handling 500W from DC to 2.5 gHz. ...

Re: ADC Punch Block Tool

Just curious... What do you need a patch bay for? I am curious as well. I haven't done a new build with a patch bay in many years. The last analog cluster studio facility that I built, nearly twenty years ago, used a combination of Broadcast Tools switchers and a cross-point switcher, all under com...

Re: Commercially available replacement for the ATU-20 Coupler

After digging out my manuals for the ATU and TCU couplers I stand corrected - they seem to be the same circuit, and either can handle antenna or carrier current..

Re: Commercially available replacement for the ATU-20 Coupler

Do you need one for carrier current or for antenna matching? The ATU series (ATU-20, -30, -60, -100) were designed for antenna matching, largely for TIS stations but also for commercial broadcast. The TCU-30 is a different beast, used for either carrier current or antenna matching. The TCU-30 is som...

Re: Burk ARC-16 ESI Card

A lot of VoIP phone systems don't like modem tones and do weird things with them That is because VoIP phone systems almost always do lossy compression using a bit reduction algorithm, so the modem signal that comes out is not the same as the one that went in, and the receiving modem cannot extract ...

Re: Wanted Gates BC-1T or equivalent

I may be able to borrow and scan a BC-1T manual if you end up with one, but the transmitter itself went into amateur service years ago and so is not available. I have a scan of an ITA/Wilkinson AM-1000A manual if you end up with one of those.

Re: Barix Audio Issue

You need to answer the questions that Kevin Kidd and Deep Thought have asked before we can help you. Getting some of the Barix boxes to work over the public internet can be chancy at best because of insufficient buffering.

Re: Is my Rate too high or is the owner high?

I charge $50 per hour for stations paying a monthly retainer and $100 per hour for those not under retainer. I charge mileage for stations outside the local area. Stations not paying a retainer get me when I'm available - they don't get the emergency service that retainer stations do. I am also very...

Re: What type of "bridge" is used to tune Directional Arrays?

I think it is some sort of impedance bridge that works under power but I'll be darn'd if I can remember what it is called... and who makes them or who made them. You are probably thinking of the Operating Impedance Bridge (OIB) from Delta Electronics. 2 - Is there a procedure online or elsewhere th...

Makes more sense to insert something like a Symetrix 528E in the program line--and use that to feed the audio stream.
An Aphex Compellor is a better tool as it is designed for high fidelity audio and the Symetrix 528E is a voice processor.

A good person to talk to at Nautel is Steve Braley
I'll second that. Steve is the go-to guy in tech support for the ND and XL series transmitters, and perhaps the only person left in Nautel support who has substantial hands-on experience with those series.
