Re: Microsoft Outlook problems?

I use Outlook "365" now but have used it under various versions for years. The only time I've had a problem is when the *.pst file became corrupt due to a hard disk issue about 12 years ago. Are you using it as POP3 or IMAP for inbound? Also, what are you using for outbound SMTP? Are you sure your ...

Re: Harris FM 20 K pro and con views

That "free" transmitter will cost you more over the next 10 years in added electrical use and maintenance than a new solid state would. If your electric rates are a bit high then the payback is even faster. Right on! A 20kW solid state will cost about $100k in round figures new. Figure a 20 year li...

Re: Tower replacement for Two combined NON-D AM's

This wouldn't be Cookevile, would it? I used to be the engineer there in the early 2000's. Back when they were owned by Clear Channel. Got jokingly accused by the GM of buying a new transmitter one part at a time for the crappy SX1 on 780. That 780 tower wasn't in the best of shape then either. The ...

Re: Harris HT5 IPA replacement

I ran a HT5 at my former job that way for many years. Needed 3,800 watts TPO and 125-150 watts drive from a Nautel VS series did just the trick. The drive required varies with the tube a bit. Use the exciter mute control line to enable the output with the plate supply. Ran it that way until it was r...

Advice on refurbing an Optimod 9100

I have an Optimod 9100 still doing main duty here that has developed the dirty pot syndrome. Just putting your finger on a control makes a nice scratchy sound on the air and levels jump all over by themselves. I figure if I am going to pull it and fix it, I might as well plan on replacing the 30 yea...

Re: Small and robust sound card. Recommendation?

In PCI/PCIe interfaces and not spending the big bucks for a pro card like an ASI, look at the Asus Xonar series. I have good luck with them. The are unbalanced I/O though. Available in sizes to fit a small form factor case. I have been using the Focusrite Scarlett USB devices of late. Put one in our...

Re: ARC-16 problem

By chance would you still be using the original ribbon cables between the interface panels and the main unit? I have had a few where the crimp on connectors got just enough corrosion after 25+ years on the IDC "forks" that erratic operation was the norm. Replaced them with some generic DB37 cables a...

Re: FM Antenna Tuning

Just to update the thread, this Saturday we'll pull the top bay to the ground to make repairs of a lightning hit that ripped a hole in the bay. I'll shut down the other class C that has the antenna located directly underneath this one and take some measurements with my SA/VSWR bridge combo both befo...

Re: Replacing sample lines

Thanks, folks. You gave me just what I needed. Sounds like LDF4 is the way to go if they need to be replaced. The TDR shows the bad spot in the cable is right about where it crosses the swamp, so I am betting on it being an actual bad cable, but it wouldn't hurt to swap the Delta TCT's and the short...

Re: FM Antenna Tuning

You may be on to something there, Kevin. The other station has a big gray ERI barrel sized filter in its line to pass its frequency and reject the other. This station has one of the filters, but it is not inline. Why it is not, I have no idea and no one is left that could answer that question. Both ...

Re: Replacing sample lines

The station is WAAV licensed to Leland, NC. It is 5 kW Non-D day and 3 towers night at the full 5 kW. The night pattern is a parabola pointing straight at Wilmington and out to the ocean. I am aware that all the sample lines must be the same electrical length, hence a buried vault at the rear of the...

Replacing sample lines

I have a bad sample line to the reference tower on my 3 tower 5 kW DA. The existing line is Cablewave FCC38, no longer made and unobtanium. So what style of line would be best to replace it with considering cost, long term availability, and appropriateness to the use? I haven't been involved in a jo...

FM Antenna Tuning

In the process of prepping the site to install a new GatesAir FAX40 I worked all day Saturday to remove an old patch bay, install a coax switch, install a BDI power monitor and switch controller, and re-plumb the retiring Continental back in. Ran on the aux site for the interim. After getting the Co...
