Ingo,

Interesting. I'll try that.

I purchased them for a gallery exhibition I'm doing, the idea to mount
the aerial's on mic stands so that visitors interact with the piece, I
don't think that they will have the range though, as you have to get
very close before causing an effect.

Thanks for the advice.

regards

David

hello david,

i have an a178 theremin, but i don't use it often.
it looks like my a178 needs some time to warm up or something
like that. i'm not able to adjust the cv offset to zero voltage
until i wait for about 15 minutes, after the the antenna was
plugged in.

best wishes

ingo
