Re: Belar FMS-2 Meters

No, I don't think so. I already have a fair amount of time and effort invested in this unit, and if I sold it, I'd just have to go out and scrounge another similar unit and start over. Now, if you had the matching TFT stereo monitor that goes with my TFT 723 modulation monitor (TFT 724) in good shap...

Re: Viavi Eastcap-1 B3030 Crashes

Well... the plot thickens. Viavi was able to use putty to check out the EAS unit and discovered that the hard drive was bad. Why they didn't discover this when they had it back for repair the last time is anyone's guess. So... back it goes again. Fortunately, I moved the installation of a patch bay ...

Re: Viavi Eastcap-1 B3030 Crashes

Thanks for the reply, Kevin. The unit has a built-in power supply fed by a standard computer power cord (I forget the NEMA number for that three pin connector, but I'm sure you know what I mean). I am wondering if it is RF related, but it is unusual in that only the top layer of software (the Viavi ...

Viavi Eastcap-1 B3030 Crashes

I'm curious to know how many of you are using the Viavi (formerly Trilithic) Easycap-1 EAS EnDec. This is the new model which supposedly complies with the latest FCC / FEMA requirements. We are using one and it will not run for more than 24 hours without crashing, requiring a power-on reset / reboot...

Re: Suggestions for FM Tuner

One rack unit would be nice, but it probably isn't a must. Here's a photo: KWPB Rack Annotated.pdf If I can figure out another place for the station automation computer, I'll have all kinds of room.... but the Belar (about three rack units), a 2 rack unit jack field, some sort of amplifier (would li...

Re: Suggestions for FM Tuner

Thanks, but that's an order of magnitude too expensive. I probably don't need to have sufficient quality to make measurements; just enough to recover the audio in the transmitter room. I have probably upwards of 500 hours and a fair amount of money into the TFT and quite a few hours and some additio...

Suggestions for FM Tuner

I am re-thinking the configuration that I want to use for monitoring at the LPFM I am taking care of. I am currently working on a Belar FMS-2 that I was going to interface with the TFT 723 FM monitor that I set up for the station. The TFT has a number of unobtanium parts in it (Z1000 nixies and its ...

Re: Studio360 Digicarts & Ubuntu NFS server?

Disclaimer: I know nothing about Linux. However, I do know someone who is a network systems programmer, so I posed the question to him.

There are a number of medium power dummy loads available as pulls from cellular phone service.

Re: ADC Punch Block Tool

Re the XLR pigtails.... The jack field is here (about $30). The punch block tool is here (about $50). The patch cords are on the way. It is too late to back out now. :D Plus, there are other advantages to being able to jack into the system at various points as I mentioned above. One other obnoxious ...

Re: ADC Punch Block Tool

For all who asked why I need a patch bay: I probably shouldn't fess this up on-line, but it isn't my station and I'm not on the board or anything, so I think I'm safe... especially since it is Trilithic's (now Viavi's) fault. Their new Easycast EAS box was crashing as often as two or three times per...

Yes, I'm also 99+ % sure... so much so that I have started looking for patch cords. They are a bit pricey. I think I'll put a want ad here in the Virtual Engineer For sale / Trade / Items wanted forum and see if anyone has some used ones lying around that are more affordable. Fortunately, I have onl...

Re: ADC Punch Block Tool

Thanks for all the replies. There seem to be some differences between the Mark II and the Mark IV patch panels. I could not find a consistent relationship between the "Krone" system and the ADC blocks... some people said the same and others gave an indication that they would be different. The Marker...

ADC Punch Block Tool

I just bought a used ADC jack field (patch panel) from eBay. The ADC catalog number is PPA3-14MK11N0. In looking at Marketek, they have a couple of punch block tools supposedly for ADC, but one of them prices at over $400. That's in excess of 10 times what I paid for the patch bay, and way beyond my...
