Re: STL dropouts....back today

Wow, I like those maps. That could also explain why we in South Mississippi are always getting slammed with New Orleans stations at certain times of year.

Re: STL dropouts....back today

The map (I assume powered by Google) had my studio and transmitter site plotted and I just put the X points right on top of each one.

I cannot raise the Tx end, but I do have room to raise the Rx end about 100-150 ft.

Re: STL dropouts....back today

There are no large lakes between the two sites, there are some creeks, etc.. We shoot from our studio to 3 different transmitter sites and this is the only site that experiences issues. The other two sites receive dishes are higher than the studio, this one is lower.

Re: STL dropouts....back today

So, more thinking on this. Perhaps we don't have enough antenna height on the receive end. STL transmit antenna site 97.5 M =319.88 ft sea level? + approx. 170 ft of antenna height STL receive antenna site 73.0 M =239.501 ft sea level? + approx. 250 ft of antenna height Distance is approximately 30 ...

Re: STL dropouts....back today

We have one of those 950 bandpass filters from Moseley and it has historically still dropped out with it in line. I stopped by the site last night and the signal was as always excellent. I did change the Attenuator setting on the Receiver to "OFF" rather than automatic. According to the manual: "OFF...

STL dropouts....back today

I think I posted about this a couple of years back. We have two 950 Moseley Starlink systems on the same path about a 20 mile hop. We have the Crescend 10 watt amps on the studio end, and we also have the big 6' Mark Grid antennas on both ends. On paper there are no issues with the separation in fre...

Blower Bearings for CSI 20KW

What size bearings are in the blowers for this transmitter? The model is Centrimax CXH33A33C 220V. I had one guy tell me that they were standard alternator bearing size...is this true?

WTB Audioarts D75 18 frame

I wasn't sure which subforum to post this in but I'm looking for a used Audioarts D75 18 frame (the frame size matters but the channel count is less critical). What have you got?

Audio Science Cards

We are currently using the AES outputs on a 6114 card for our (3) on-air outputs from our Wide Orbit automation system. It has sounded really nice for several years, but every so often one of the outputs doesn't sound as "crisp" as the others. We are running Linear PCM. There are several of these ca...

Re: XDS Relays Not Working!!

AH!!! I didn't realize, nor do I recall it saying in the manual that you must hit "set" after changing a relay to 1 for testing purposes. Now I'm on the right track. Thanks for your help!

XDS Relays Not Working!!

We're automating one of our shows for the first time and I cannot get the relays on the XDS receiver to give me closure. I've been on the phone with Westwood One and they even sent me another receiver. The receivers have a test screen where you can manually fire off the relays from the front panel, ...

Duct Fan for back-up transmitter?

We use 10" duct for the exhaust on a Continental 30KW that we use for back-up. We have been running the blower and filament at all times to keep the cavity dry and have it ready to go on the air. Sometimes the power will go out at the site and the blower and filaments will not come back on on their ...

Re: TDR for 4" line?

Well we finally were able to evaluate this system yesterday with the help of Charles Ellis of Ellis Engineering in Louisiana, who I highly recommend. The 4" line tested perfectly on both a TDR and a network analyzer. We checked it open, shorted, and with a dummy load. We were able to "cap" it off be...
