Re: Harris Z FM FET replacement

As much as I hate to write (or have written) an oversized/inflated check to Harris/Gates/GatesAir, we have always returned the pallets in pairs on a heat sink to the OEM for reasons previously outlined as well as scale of economy (cheaper by the pair). Particularly the bias matter. In another part o...

Re: FCC FM Query Data Base

Don't confuse the FCC's use of HAAT and AGL/ASL. The latter two are absolute. Rarely does the AGL/ASL match the HAAT. HAAT is a derivation of an average of 8 averaged radials 10 miles long. In fact, there are many instances where the HAAT is a negative number. Such as when a site is located in a val...

Re: solar power

It's common in areas where utility power is a PIA and the needs are modest. It really boils down to your needs as the array can be as big or small as you want/can afford so long as the inverter is the right size. Couple things to keep in mind: 1) Will you generate more power than consumed. Then you ...

Re: BE AM-6A RF Out Problem

Dave.... When you adjust the matching network into the dummy load, does it change the reflected power at all? Do you see any current on the base current/common point meter when driving the antenna? If not, then the TX is clearly not putting out any power at the stud. I agree with Kevin that it could...

Re: Negotiating with the tower conglomerates

Not entirely true. The 501c-3 is a PIA to account for on the donor side. Especially in non-tangible things such as services and space-available amenities which there are no otherwise paying customers being displaced or obstructed. More over, all the buildings I've ever dealt with which didn't requir...

Re: Tower Identification

This looks like a Blaw-Knox. They were popular in the 1930's to early 1960's before Blaw-Knox left the tower business. Especially with AM's not needing super heights. I will say this does not appear to be a Truscon as it doesn't have the trademark triple member legs and is not a conventional triangl...

Re: Looking for a Sage ENDEC 3644

The matter of charged firmware updates was specifically brought up in various NPRM's over the years as an undue burden foisted upon licensees. The FCC simply sniffed the matter and said it was a cost of doing business. Well....so is the fact most stations have thumbed their collective noses at the F...

Re: Rad fiber "demarc" device--aka modem (?)

We find this every time we get in new IP service. You need to call the ISP vendor tech support and have them either open up the desired ports or walk you through the steps in their modem's firewall when on site. ( you better have the account number, circuit ID, all security PW's and customer selecte...

Re: Harris DX-50 raise and lower problem

Is APC enabled? Can it be toggled on/off?

Can you adjust power by the remote control terminals? As I recall the DX series, the remote terminals are different inputs to the master controller.

Re: harris gates one retune

I will be retiring a 1985 SX5A shortly (barely working) and a dead 1980 SX1 next year. I also retired a 1991 Gates5 (working well) 4 years ago. All for the same reason---support is largely gone. It is unfortunate that Harris, then Gates, now GatesAir has dropped the ball on AM TX's. Even if they com...

Already sold.

I may one coming available at the end of the month after a station sale. Would be in the same price range.

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

It's the money. Plain and simple. Most institutions are cashing out since it takes money, more than many will admit, to operate schools stations. What doesn't appear on station bottom lines are hours and hours of labor by administrators and assistants to manage the stations and their underwriters ab...

Re: Audio dropouts on Yankees game broadcasts

They don't shut off the HD or profanity delays for real time monitoring, they shut it off the for the fans to hear the PBP. There is way too much latency in the feed to the station, let alone the transmission chain, to have the broadcast team listen off-air. Many local stations will also willfully d...

Re: Sage Digital Endec logging best practices

Our practice, vetted by counsel, is to just print that week's activity and then simply attach that printed document to the Station Log. Nothing more needed. Don't over think the matter. You don't even need to manually enter the date/time. The activity log when attached becomes part of the Station Lo...
