Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

Nathaniel, I have aimed about 25 dishes now....many of them that Comtech dish. To me, those are the easiest. I use my digital protractor on the flat part of the back to set the elevation, then swing left/right until I see the plot I'm looking for on the analyzer. On some receivers, I've had to manua...

Re: Broadcast Technology Company?

Also, they were located at KANZ, so you might call the station and see if they have any documentation left over.

Re: Broadcast Technology Company?

Maybe a year and a half ago, I called (620)290-2263 and a guy answered...I asked if it was Broadcast Tech, he paused for a second and said "used to be"...I apologized and said I was looking for a schematic...he asked for what product...I said BT300...he asked for my fax number...a few minutes later,...

Re: Nicom BKG 77

Damon, I can say from experience, having built over a hundred translators...the simple answer is: probably not. Knowing a little more about the height, intended coverage area, etc...would help. The single bay setup with higher TPO will almost always have a more omni pattern with less multipath and b...

Re: Phelps Dodge Antenna Rebuild

If you'd like to get other opinions, here's one: Take the antenna to the scrap yard, get the money for the metal, and put that towards a new antenna. Seriously, this thing isn't worth messing with. It's not designed to change frequencies, and these never were great antennas, even when new. Depending...

Re: Gates Air Flex20 vs. Nautel NV20lt

I've done 3 GatesAir Fax installs and 3 Nautel NVLT installs recently. I'm kinda underwhelmed with the GatesAir product. I've had numerous issues with both...the most recent being that one of the Fax boxes keeps losing its metering calibration. External wattmeter will show that we are putting out co...

Re: Good ole analog

Pretty much three consistent failures on the Nicoms: 1. Power supplies. Usually either a cap or a voltage regulator. 2. Output device in power amp. They have used a few different ones over the years. Not much protection from VSWR or lightning. Either will cook em. 3. Bad solder joints. Some of these...

Re: Good ole analog

I do a fair amount of bench repairs. I have fixed a LOT of Nicom STL units. They seem to last about 2 years. Poor design. The Armstrong X-Link are my favorite of the current analog products. They are an RVR design. Very serviceable, and I have seen very few failures. Keep them cool and clean and may...

Re: Worst FM Transmitter

We kept a Channel 6 dual cabinet NEC TV transmitter on the air from 1986 to the day they made the flash cut to digital (Harris Sigma). The NEC was a great box. The audio amp transistors were impossible to get in the later years, the thing was down to 2 or 3 audio amps working towards the end. I have...

Re: More STL power needed

I have one of these Bext 40 watt STL amps on a station near the gulf coast with a 28 mile STL hop, it helped us overcome the "gulf fades"...haven't had any issues since installing it. STL dish on the TX side is a 6' Mark at 120 feet, on the RX side we have a 6' Mark at 800 feet. No preamp. http://ww...

Re: Tower rental rates

I have recently been looking at tower rental rates as part of a bigger upgrade project for one of my groups. I was actually really surprised at how high they were in North Florida. 5 bay ERI at 600 feet on a Crown Castle owned tower that's mostly empty with an 8'x10' floor space in their building, w...

FM killing C-Band

New one for me...I have a BE FM35T 35kw tube transmitter with a 3.8m C Band dish adjacent to the building. This has been working fine for years with the C Band feeding a Premiere XDS receiver and an ABC Wegener receiver. Recently the station added another XDS receiver on the Clear Channel carrier......
