Re: Sage EAS 1822

A ham radio group might be interested to decode wx alerts for a rpt OR you might could use it as a confidence monitor for customers EAS transmissions. As far as I know, it should decode and log (serial...) most data even if the new codes aren't recognized. If you are going to junk it, I will pay shi...

Re: Recommendations for EAS box?

100% on the Sage. Easy to program , use, etc. They are also charging for the new TLS certificate, but it's only like $300. I concur on Sage. I am highly upset at Dasdec. As far as I know, Sage, DasDec and Trilithic are the only units available and Sage is by far the easiest to setup and operate AND...

Re: Equipment Performance Measurements

Well I started with the IBOC measurements right at the transmitter. Those failed. High baseline noise level and more than just a few peaks exceeded the IBOC mask and even the 73.44 mask. We noticed the mod monitor seemed to be reading low negative modulation so we spent a few minutes checking the b...

Re: Tower Lighting

I just had a tower retrofitted to LED top flashing and steady side lights. The tower crew removed the 300mm beacon and replaced it with the 120vac top beacon (complete with IR beacon) and replaced the side light fixtures with the new LED fixtures. I built a new controller / alarm for the new lights ...

Re: IS GATES AIR STILL THERE?

I haven't seen anything on any of the other lists that I am subbed to.

The last that I heard, they were more stable but who knows.

Re: Equipment Performance Measurements

I concur on Deep's thoughts and will add that a former FCC EIC told me that they are as interested in a stations diligence to comply as the compliance itself. I have zero experience with NRSC testing on an IBOSEC site. If you want to cover all bases, do a test on the backup with a note that the stat...

If you are really into self flagellation... You can do the measurements and calculations yourself.

Re: Quick STL Question

Keep in mind that a lot of the older Marti and other STL transmitters use RF modules that are unobtainium. Often another available module will work at lower power but I haven't had real good luck long term with those conversions. Additionally, some of the Marti receivers have VCO (IIRC) modules that...

Re: MOLEX CONNECTORS FOR AUDIOARTS R10

Seemed like I juat dug out this information not long ago--maybe on the Broadcast mailer. They are not molex--made by TE Connectivity. Have all the part numbers--but not on the office computer. Will post them tonight. That was me looking for the 12 position shells and pin/sockets for an R5. I ordere...

Re: Where are EAS Location Codes ?

What brand EAS decoder? The Sage programming software shows counties and states, which is really all you need. As does the Dasdec IIRC. You shouldn't need much beyond the local county/state names for any compliant EAS unit. Some of the OLD, OLD, OLD EAS units required a direct FIPS code entry. If t...

Re: Sample lines: curiosity question

And then there was the large Iowa array that someone thought it would be OK to convert the 3/8in unequal length sample lines to equal with various lonnnnnmg lengths of RG8. Some of the RG8 was inside, some outside... It didn't work out very well long term. I have only worked on a couple of arrays th...

Re: Replacing sample lines

Cablewave 3/8" FCC38-50J is 81% while Andrew LDF4-50 is 88% velocity. Bad things happen when you replace one with the other. Andrew FSJ4-50B is 81% but is really too fragile for long runs. From an FCC standpoint, the lines must measure equal in electrical length within 1% and within 2 ohms characte...

Re: FM Antenna Tuning

You could also be seeing some of the other 100kw signal as reflected power. Ask the other station to reduce power to 50% for a few minutes and see if your reflected power drops. If so, your new power meter is reading their power coming back down your feed line.
