Other than the HP I just mentioned in my last post... I cut my teeth on the Halcyon... and it was actually a very easy/nice unit to use. Not to mention it is/was very well made. We beat the snot out of ours and it never died.
Helper Instruments never made a bad box that I ever saw. I have a number of their boxes... I'll even get around to scanning the rare/elusive Helper Catalog with Company History if anyone is interested. And I know a small bit about the Zetron part of Helper Instruments. Vega even made a tone/line test box... Since people often don't know what these boxes are used for... they go pretty darn cheap on ebay. cheers, skipp > "Steve Bosshard (NU5D)" <[EMAIL PROTECTED]> wrote: > I use a TIMS Meter - transmission impairment measuring > system - Halcyon, Convex, NT, even Helper Instruments > made a nice $300 box for basic testing. > Steve NU5D >
