Re: AM primary station to Translator separation

It's the greater of 25 miles from the tower or 2mv/m contour. Always check at ECFR.GOV for the current rule: "The coverage contour of an FM translator rebroadcasting an AM radio broadcast station as its primary station must be contained within the greater of either the 2 mV/m daytime contour of the ...

Re: Exciter shopping

Some models of the RVR STL transmitters--and receivers, don't have very well shielded IF oscillators. Had problems at a combined site when two receivers were put too close together in the rack. At another site, the STL transmitter blocked out a weather receiver used for EAS. Moving it to a window cu...

Re: Marti SRPT-30 frequency change

Simplest to send it back to the factory. My notes indicate it cost me $314 to add second frequency to my RPU transmitter.

Re: base insulator

Thanks, but we have the budget to go mostly new on this project. Shipping from Canada is very reasonable, too, about $130.

Re: base insulator

Heard back from Austin--reasonable price. Got to wait until the end of the month--church selling their AM & can't have full congregation meeting until that last Sunday. The Rohn tapered base section --listed as a 55TG1A--is supposedly designed for this insulator. Will be an interesting project, last...

base insulator

Looks like we are buying an Am station. And will have to move the tower. Class C/kilowatt. Plan on using Rohn 55G (I have 50' of almost new sections), found a source for the tapered bottom section--but now looking for a base insulator. The Rohn base section is designed to mate with an Austin A-4197-...

Re: Microsoft Outlook problems?

With Rackspace we are only paying about $30/year per active e-mail address, not sure what our mailbox total could be with the present account. The Outlook problem I suspect is something connected with the notorious Microsoft updates. Program will lock up, not allow e-mail to be sent or other problem...

Re: Microsoft Outlook problems?

We use Rackspace for e-mail, rarely have any problems--and when there is a problem seems to be their problem. In fact, have link on another computer (same network) for my business partner's house e-mail which I've had to resort to when Outlook wouldn't let him in.

Microsoft Outlook problems?

I don't use it, our e-mail provider has a simple interface. But my business partner and our Microsoft indoctrinated office manager insist on using it, completely impossible to get them to think of using anything else. Which is causing problems, since Outlook has been locking up, acting strange. Toda...

Re: LPB series III referb

What kills most of those older consoles is bad switches and bad faders. Switches get intermittent, faders noisy. Both difficult to replace. If these are OK, then a simple refurb would be to replace filter caps in the supply and bypass and coupling caps on the circuit boards. Easy enough to do if you...

Replaced by a Gates Air 3.5--considerably smaller, which is nice. Three stations at this site.

sat look angle calculator

There used to be a good one on-line I can't find anymore. Used google maps, had the right satellites for North America, and showed the direction on the map. Need to see if we can get SES-11 at our one studio site--may be adding a station & plan using some satellite fed programming. Site wouldn't wor...
