You must all remember, though, that the first rule of intelligent tinkering is "save all the pieces" :smile: Yeah, if I can figure out how to take it apart I can usually fix it. Several years ago my snow blower stopped working & I had to take it apart to figure out how it worked. I fig...

We're kind of straying from the topic here Bigglez but that's OK by me. I happen to believe that a business owes something to it's community/society in addition to owing something to it's shareholders, and that the obligation to the community/society should, ultimately, take precedence. Perhaps busi...

When circuit city fired all of their senior sales people and said they would allow them to reapply for their jobs at a lower pay rate some months down the line I decided that that was too much. I refused to do business with them (figuring that the lower prices came at the cost of people's pride &...

ATTN Bigglez & MrAl,
The adults are trying to have a conversation here and the two of you are being very disruptive.
Please go to your respective corners, take a time out and think about how you've been behaving.

Here in Wisconsin they say we have the highest percentage (20%) of OTA- only viewers in the nation. Lots of rural area and cheap people. I understand and have found through my own experimentation that the type of antenna isn't important. The RF is RF and almost any tv antenna will work if you have a...

Sounds like an impedence mismatch twixt the phone ckt & the tx amp ckt. I'm guessing that most if not all of the audio & RF are on a single chip & what's left is input & output conditioning. What are the odds that the transformer is for Z matching? 600 ohm to something lower? Excelle...

Since this is an existing building they will be using the existing phone wiring so that's not much of a consideration. OK, here's the scoop. Viking door products has a single gang, stainless steel hands free door phone that can be connected to an analog phone port programmed for ring down to the cus...

Len, OK, I gotcha. You're right about the line intercept concept. Way too complicated & peril fraught. A good example of "just because it can be done don't mean it should be done". I do not like mag locks for primary security for the reasons you indicate. As a matter of fact this will ...

Len, Excellent, this is starting to take shape. Please tell me though why you are apprehensive about connecting to the pbx instead of a dedicated line. I can think of a few reasons...compatability with a given switch, I'd have to turn my wires over to the telephone guys for them to connect and progr...

LenP, Yeah, great minds must think alike. I was taking a shower at the gym this morning when that possibility occured to me. I'll have to look into their tel. system & see what will work. I wonder if you have to actually have a phone line or if hanging the I/C adapter on a line port will work. A...

Good question. I guess I gotta say that in the long run I don't trust RF for permanant commercial or mission critical applications. I'm a communications tech by training & trade and probably spent half of my 30 year career doing two-way radio and RF system maint. & repair. RF interference, c...

Anyone out there ever use IP intercom? I have a request for intercom from one door to several places in a large building. Cable runs in this building are time consuming and iffy enough that if I quote a dedicated wire I/C I'll have to examine almost every foot of path just to be sure I get no unplea...

Come on folks, the thing is "not how well the bear dances, but that the bear dances at all". For folks like us these things are intellectual exercises, not an attempt to aquire perfection or utmost efficency. Keep tinkering, you never know when it might spark another idea and heaven forbid...

No, we had a few Olsens here in Milwaukee, but Akron was our Mecca. All things neat and far out came from Akron. We sold a line of Italian stereo amps & tuners (I forget the name) but they had beautiful cherry enclosures and the circuit boards were all hand soldered, excellent sound also. There ...

Yep, first job in the electronics industry, must have been right around 1970. Worked sales & shipping/receiving. Sold a lot of tuner cleaner and showed people how to use the tube tester. Thanks for the welcome, nifty little forum ya got here. I've been lurking for awhile but had to add my 2 cent...
