[Lowfer] E probes .v. loops

Thu, 11 Sep 2003 07:30:37 -0800

Thanks Steve - Ill  have a play - I last looked at "active whips" in the 
70's in Antarctica but I wanted a way of gettin a more transportable system 
but as you say the Loop will win....I dont think this is going to work for 
Mexico so I wont bother taking anything....then perhaps Ill just throw it in 
the luggage anyway..... If I had a remote cabin or whatever they call them 
it would have worked, but as its my honeymoon I may be a tadge busy 
elsewhere.

Thanks for the info on the beacon, I await audible results!

I had that annoying unresettable trip on one of the chips which, as of yet, 
have yet to determine that fault to Ive disconnected the line for the time 
being. All the inpots to the reset/trip chip are dc wise wise so....more 
work needed here but its not affecting transmissions.

and oh yes getting technical stuff foreign customs is a part of my 
portfolio...playing the part of a stupid fishing man with "tackle" boxes and 
rod tubes seems to work well  (except Africa)

Cheers
Laurence
