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.

Of course, because it will be brought up.

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.

Re: AM station to shut down at end of May 2019

There is no STA for surrendering the license since it is not "temporary". The station just submits a letter with the license (or a copy of the original) and requests that it be cancelled. In this case it appears they're still hoping that someone will buy it if they are filing for STA to remain sile...

Re: AM station to shut down at end of May 2019

I have had a few AM's go totally dark over the years and IIRC, they just had their attys send the FCC a letter saying that they were turning in the license. I think that they also included a copy of the original license and received a letter from the FCC giving them something like 30 days to reconsi...

United Rental Hacked

Heads up! It appears that United Rentals web server, email and possibly database has been hacked and scammers are sending out fake invoices.

Re: UNI

I don't think that's a feed skirt...I suspect that wire is the entire antenna and is not connected at the top. Performance probably sucks bigly. The FCC won't authorize a single wire shunt feed anymore. An STA app filed by Stu Graham noted "a single unipole wire" feed... It would also appear that t...
