Jeff,
Thanks for the quick reply.

I noticed from your message the Perl machine's carrier frequency is set at 27 Mhz versus the GB4000 set at 2.1MHz to 3.6MHZ. I am not clear on why the Perl machine's carrier frequency is set so high versus the GB4000.

If possible, could you possibly explain the differences between a machine with a higher carrier frequency compared to a machine with a lower carrier frequency such as the GB4000?

Is it better to have a higher carrier frequency?

I noticed that the GB4000 has a higher "Frequency Range in Hertz" but not sure what that has to do with carrier frequency.

Any clarification would be enormously appreciated!

Thanks!

Regards,

Wes
