John,

I would suggest somewhere between 137.680 and 137.720 for QRSS3. A lot of
the EU grabbers are centred on 137.700, so you're more likely to get noticed
if you operate in this frequency range.

I doubt that you'll be able to get to the UK in the daytime with 30W carrier
power, but with QRSS30 it should be possible after dark.

Antennna: inverted L.  Estimated effective height 6 meters,

Feed current: 410mA,

Frequency: 137.000Hz from a HP3325B generator plus Class E PA delivering
nominally 30W QRSS3.

What would be the best frequency please?

Any other suggestions?

Thanks.
