Hi Richard.

Mind if I ask for one for a different frequency range?

 > 1. variable frequency or fixed?

Variable - to cover the range 100-200 kHz in 100 Hz steps or better.

 > 2. output waveform type

There's two versions I'm interested in:

 a. Switchable Sine/Square wave.

 b. Dual Sinewave, with a fixed 300 Hz between the frequencies.

 > 3. power source 9vbatt or 110ac

Here in the UK, mains is 240V nominal, and I'd prefer it to work on
that, but also have a facility for running from a standard car
battery.

Best wishes from Riley.
