Hi,

I use this homemade one - works into the current range you are looking
for:

Works great.

Have fun,

Hi all at LF,

I have been conducting tests with QRS & DFCW now that I have completed the
DDS VFO & the antenna is back up after storm damage & everything seems to be
ok.

The main reason for this e-mail is to ask this question,

"When I have looked at designs in amateur radio magazines or internet for a
clip on RF Ammeter the designs seem to be limited to 2 ranges (100mA & 1A
FSD), is there a limit to the range of this type RF Ammeter or can the
ranges be extented to say 5 Amps maybe? is there a calculation to extend the
range ?"

My LF antenna seems to be showing in excess of one Amp so I need an RF
Ammeter with a greater range than 1A.
