Re: High Pitched Tone in FM Audio?

If the holes in the top cover are counter-sunk, then it probably wants phillips flat-head screws. If not, then ordinary phillips round-head or pan-head screws with a split-ring lockwasher and a flat washer. The thread size will need to be determined by trying some other screws of known size, but pos...

Re: Harris CD Link

I think you're on your own. Harris did the same with their Aurora series of 5.8 MHz link equipment, wanting more than the units cost just to check them out. You should be able to buy another power supply if you can figure out what the original is supposed to be putting out. The size seems to be an i...

Re: INTERNATIONAL CRYSTAL MFG

Considering how crudely the ICM web page looks, I almost get the feeling it's fake and has been spammed. But it is an interesting coincidence that RadioShack's parent company also declared bankruptcy a few days earlier. I too want to get some Crystals for a 10M base station. At one point they were a...

Re: Quiet UPS

By the way, when I said "extension cord" earlier, I didn't really mean to lay one across the floor and incur the wrath of the fire inspector (been there, done that). I was thinking of running some conduit and making a real branch circuit fed by the UPS, so you can get the constant power from a UPS i...

Probably the next sequence after 1620 kHz.

Re: Quiet UPS

I was given an Eaton 5PX-series with what appeared to be battery issues (another one where they waited 6 years before changing batteries) but this one had an odd situation. It worked fine on utility power, running a small electric motor. When I pulled the power plug the front panel said 120V 60.0 Hz...

Re: Quiet UPS

I too have had the bulging battery syndrome with APC UPSes. I needed to take the top cover off and use a pry bar on an SU2200 that had 8 batteries inside it. In all fairness they were at least 6-8 years old and were far overdue for replacement, and for some reason the whole unit was scrapped - into ...

Re: Quiet UPS

The APC SmartUPS series, at least the ones I've encountered up to 2200VA, are NOT true on-line units that run the load off the inverter 100% of the time. They pass ordinary AC through via relay contacts then switch to the inverter when utility power fails. The larger units (SU1400 and larger) have f...

Re: Locked up browsers

When something seems locked up here, I glance over at my router to see if there's any network activity, and there never is. It seems that if an application requests data over the network, it is then suspended until that data is returned, hence the application appears to hang. It has to do with the w...

Re: TOH time tones

I can't get any of the NYC FM stations where I live due to a 450ft rock about 3000 ft SW of me in-line with NYC. It also doesn't help that WCBS-FM/101.1+IBOC is one channel away from WKCI-FM/101.3+IBOC right here in my town, so I haven't a chance of getting WCBS-FM OTA. I'm close to buying a wifi in...

Re: TOH time tones

Regarding radio vs TV audio delays, these are NY Yankees broadcasts on YES network as well as Ch5 (FOX) in NYC, and a local that picks up MY9 broadcasts sometimes, which I can't watch because their DirecTV signal is too wide to watch on a standard def TV. The radio station is local with profanity de...

Re: TOH time tones

Sometimes I get fed up with the constant jibber-jabber of the TV sports announcers, I mute the TV and turn on the radio to listen to the radio sports announcers. I will then try to synch the TV picture with the radio audio. This used to work, but the current DirecTV box I have won't let me delay the...

Re: TOH time tones

I was reading this post at 8:59:30am EST Saturday morning and quickly turned a radio to WTIC/1080 to hear it. Just as was said above, "dit-dit-dit-dah", Morse Code for "V". However it sounded a bit out of tune to me, like musical notes "A-A-A-F#" rather than "A-A-A-F". It punched through loud and cl...

Re: Valcom

"Never knew they involved a helix inside. So, basically they are oversized rubber ducks!" Well, you have to get about 200ft of radiator length into about 85ft of height somehow. Besides helical winding, there's also a loading coil in one section. Also, they aren't nearly as flexible as a rubber duck...

Re: Problem with AM-19

Another much lower probability is the SCRs that drive the relays on the input card. If one opens, it won't pull its relay in. They are all mercury-wetted relays that must be installed in a particular position so the mercury doesn't short out the contacts when it's not supposed to. You can pull them ...
