The silly thing is that the component cost is so small!
Two NPN transistors, possibly only four resistors, a high resistance
piezzo-electric device , battery, a light sensitive diode, and something to
put it all in!

I was thinking of a light probe that would just see if a LED is lit.
A number of us (including myself) have older variations, but a newer one at
an affordable price would be helpful.

Hi Tom
Do you actually mean a light probe for "reading" or just seeing if a LED is
lit?
I have my old and trusted one in a square case, which, when on its side the
diode is just at the correct height to check the LED's on my KAT500.
I agree with your suggestion of an antenna analyzer.

Terry and all:
I still think a stand-alone affordable talking watt/SWR meter to replace the
TW1 and TW2 is essential.
Also, an affordable stand-alone talking antenna analyzer would be
beneficial.
Finally, how about a newly-designed and affordable light probe for reading
LED read-outs and the like.
In saying all of this, I know there are some on this list who are at various
stages of designing or at least considering the design of these items, so
I'd not want to duplicate efforts.

Hi all,
The RSGB President collared me last night at the GMDX Convention. The =
Society wants to do something (spending some capital) that would be of =
benefit to its members and enhancing the amateur radio experience for =
people with disabilities is one thing that's being considered.
Whilst this initiative would be aimed at RSGB members in particular, it =
could also be of potential benefit to others.
I'm in no position to make promises and have no part in the decision =
making process.
I was asked, however, to come up with suggestions and I'm concerned that = I
don't just propose a re-invention of the wheel.
So, what would we really like? Power meters have been mentioned, but I =
think these already exist, albeit in some expensive options. I had some =
thoughts about the experience with digital modes, but perhaps there are =
already solutions here too.
So, come on, let's hear it and I'll try to draw some kind of = constructive
consensus.
Cheers and 73,
Terry
