Re: LF: RE:G4HUP aerial current meter

[<i.frith@ntlworld.com>]

Hello Allan

I assume the 10A mod is a matter of increasing the series R with the meter 
to around 800k?
I suppose a 3way switch and extra trim pot could be added to preserve the 1A 
range too.
Thanks for the note re-shipping Monday.

Look forward to getting the Kit.

It has just occured to me that the 1A range may not be high enough for some
of the LF QRO merchants. There is a simple mod which will extend the range
up to 10A though you should be aware the ferrite core has not been tested at
this level of RF. These cores are used on mains leads carrying up to 13A so
I think they will be OK.

Thank you to those showing interest, there are a few kits still available.
