Many many people use Bluetooth with cars these days, so they do in fact have them on outside.

Not to mention a few million Bluetooth headsets.

There is traditional remote analog metering and control, IP web-based control which duplicates the front touch screen, and a button panel inside the unit to manually control it locally if the screen dies.

Almost all smartphones have both Bluetooth and WiFi and most people leave them running even though they're not being used. There is big money in tracking customers as they wander around stores using the MAC and/or BT address to identify each phone and the systems to do it are commercially available....

At least that one has a touch screen. The lower power versions just have a little bitty generic LCD screen/button assembly in that big space where the touch screen is.

You might want to get in touch with Mike Patton, who may be interested in the ND bits.

RR tracks aren't really a big problem as long as the ground system is designed to accommodate it. I did a six tower inline here in the Chicago area with a spur running between towers 3 and 4. Trains never really upset things much, and this was a critical array (back when such things existed) with hi...

The forward power meter is at the top with a low/high/off switch. One easy meter test is to set the transmitter at 300 watts (full scale on the low range) and see if the two ranges agree. If there are mechanical issues with the meter it won't go full scale on the low range, but any issues with the r...

Upon leaving the site, I encountered the entire herd standing out by the paved road. The so-called "cattle gate" was just a minor impediment to their freedom. I did a new DA tune/proof outside of Tampa once...about three gates deep into a large cattle grazing operation. The rancher wanted us to kee...

How far up is the FM antenna? Wind turbines generally don't rotate fast enough to cause major problems at FM frequencies, and any multipath from them would be unnoticeable once you got a few miles from the site as it would all "look" like a point source to the receiver. I wouldn't be trying to run a...

The meter switches on that series of transmitter are failure points. Check to see if the remote sample is working, and if it is then it's the switch.

You might try Mike Patton. He usually stock repair parts for these things.

Yeah, if it was after about 4 PM that low of a MP value can be affected by the onset of skywave propagation. I once did an antenna proof in November on a station on 830 KHz in northern California and had to quit taking readings on the backside of the pattern around 3:30 due to WCCO contaminating any...

Win7Pro. I have Grant Binghams network design and it refuses to run on "some" installations of Win7 (32 or 64) and any install that I have tried it on Win10.

Interesting. My copy runs in Windows 10 x64 without much whining about it.

What version of Windows are you moving from? If they ran in 7 they should run in 10. There are some real old programs that are actually 32 bit but have 16 bit installers which prevent them from being installed on any x64 flavor of Windows. There is a workaround, though. If you've got old DOS stuff, ...

Check the AM noise...I'll bet it is very high and the IPA power supply has issues especially if the power was going bouncy bouncy during the storm. There is a 36,000 uF/100VDC filter capacitor on the IPA supply (C4) which you might want to take a look at. Are the IPA voltage and current both "normal"?

deionized, demineralized water As counter-intuitive as it seems to those who have never worked around a water-cooled tube transmitter, pure water is a good insulator. The trick in your laptop story is that there was nothing to leave behind once it dried out. I have to imagine that the cooling fans ...
