Back in the day, KCBS (channel 2 analog for Los Angeles) used a Modulation Sciences TSG as the primary processor with an Optimod TV for backup. Both ran BTSC composite stereo into Larcan exciters which had a wide band non-preemphasized input.

I will do this in the future. I thought the whole thing might be necessary for proper attribution or if someone wanted to contact an original poster for more info. However, I can always supply the address in a PM if someone wants more detail.

Thank You,

Here is the entire E-mail thread that went by many years ago on this subject. Some highlights are for: Sauereisen Cement http://www.sauereisen.com. Parker Furnace and Retort Cement from Grainger 813's are specifically mentioned on page 11. If you scroll down far enough, the formulations for mixing s...

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...

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 ...

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 ...

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...

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...

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...

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 ...

Disclaimer: I know nothing about Linux. However, I do know someone who is a network systems programmer, so I posed the question to him. Here's his reply: Jim, I did a quick Duck Duck Go search, and came up with these. They are for memory sticks, but might have something to do with the problem. HDD m...

There are a number of medium power dummy loads available as pulls from cellular phone service. Here's an example on the 'bay for less than $50. https://www.ebay.com/itm/CELWAVE-Microwave-250W-Dummy-Load-Signal-Port-RF-DL200-50-2GHz-N-Type-BNC/223937275535?hash=item3423b3a68f:g:ZO0AAOSwIBJaa2pG Regar...

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 ...

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...
