[Lowfer] newbie questions

RE: R75 question

Tom,

Being an LF newbie you may not realize that John Andrew's endorsement of the 
R75 carries no small amount of weight in the Lowfer community. He has set 
some pretty impressive records with that receiver.

I, too, have owned an R75 for about 2 1/2 years (in fact I bought mine after 
seeing John's) and 'Second' all the comments John made in his reply. I did 
not purchase the High Stability option but find after an hour warm-up there 
is virtually no measurable drift - and we are talking mostly ARGO usage 
which can bring out receiver drift of only 0.1 Hz.

If you are looking for a 'Best Buy' check out E-Bay. There's an active 
reflector for R75 users at icomr75-subscribe@egroups.com.

PS: Jay R, another fellow TX looper, beside John, also uses an R75. This 
obviously indicates the R75 is the 'thinking man's' receiver! (or is it the 
'looped man's' receiver?) <G>
