LF: Front panel lettering ?

[CHRISTOPHER OSBORN <c.cjo@btinternet.com>]

Many thanks for all the fast replies concerning my panel lettering problems.

I suspect that my hand is not steady enough for a black marker pen and results would prove illegible.
We use white labelling machines at work so may I give that a try on a test panel.
I've ordered some 'decal' paper from E -bay as I'd never come across that before and it sounds just the ticket.

Re the N.O.V. ERP measurement . . . very interesting.
On my application I made an assumption about the radiation resistance ( rightly or wrongly) and worked back to calculate an acceptable aerial current.
It's not too tricky to measure that and keep it within limits.

The current RadCom has an interesting article on 'Understanding Field Strength Measurements' which I've read and re-read several times.
Shoot me down in flames but can't one make an RF probe to measure the volts per metre at a set distance from the aerial and then work back to deduce the radiated power
