- No-one has yet pointed out that you can 'measure' it directly! No need for
- anything electrical, electronic or radio.
-
- The characteristic impedance of a line is given by the formula
-
- Zo = 138Log (d2/d1)
-
- where d2/d1 is the ratio of the respective diameters of the inner and outer
- elements of the line.
- If the line has a solid center conductor, its easy! Get out your vernier
- callipers or micrometer, and a scientific calculator (or log-tables for
- oldtimers). Multi-stranded center conductors may need some extra
- trigonometry; measure the thickness of one strand, count the number of
- strands, work out the mean diameter..... or isnt this sort of thing taught
- in math classes these days?

- Old timers may remember a hand-held multimeter that HP made many moons
- ago. It was in a case shaped like a huge cigar, with an LED display.
- There was a switch on the unit that flipped the display so that you
- could read it no matter which way you were holding it. Must have been
- almost twenty years ago.

- Hi ---
-
- The library where my wife works went out and bought a Radio Shack WeatherRadio Alert,
- Model 12-140 to let them know when there will be bad weather, etc. Unfortunately,
- the person purchasing it did not get the instruction book. Well, they did manage to
- set it up and get it to work OK but they find the alert noise to be too unnerving
- (especially in a quiet place like a library). What they really need is for the darn
- thing to stay muted until there is an alert, and then the speaker unmutes and everyone
- can hear the message .... not the way it presently works where it squeals away until
- someone presses the WEATHER button to hear the announcement.
-
- My first thought was to open it up and clip a lead on the little piezoelectric
- sounder or whatever is in there that makes the alert noise. But upon opening it
- up carefully, it appears as though the alert noise is summed with the receiver audio
- before amplification & going out the speaker. And without a schematic, I'm a bit
- reluctant to do much more. Plus how would you know there was an alert so you could
- hit the WEATHER button and hear it ?!
-
- So here's the question(s) ---
-
- There's a little switch on the back bottom plate marked "ALERT LOCK" ---
- will this make the receiver do what I want? What does it do?
-
- -and/or-
-
- Does anyone have a schematic who can tell me what lead to lift to kill
- the alert tone & make the speaker unmute instead ?
-
- -and/or-
-
- Can someone with a schematic advise where the alert tone audio is generated
- and summed in, so I can attenuate to a bearable level ?
-
- I would appreciate any and all replies (and anyone suggesting a modification is
- absolved of all responsibility). E-mail preferred as I am posting to several
- relevant groups.
-
- Thank you in advance,
