THERE MUST HAVE BEEN SOMETHING WRONG WITH YOUR MILLEN. BILL T.

I'm not using a Millen and this post isn't a troll as someone else
suggested. The meter I use started out life as a Tradiper (Japanese)
but because it was hopelessly outdated and used old germanium trannies
with enough lead inductance to tune a VoA transmitter, I decided to
rip its guts out and rebuild from scratch.

sorry I don't really see your point. I bought my Tradipper in 67, and
it has been very useful since then, I may not use it so often now
because I've also got a Philips GM3121.
Mine operatet satisfactorily - as original - up to 140MHz, but the 2M
coil is no coil at all, only a short between to pins on the connector.
Have described how to improve on this on
http://home.online.no/~la8ak/m2.htm

The other modification is to use external +12V since the battery would
normally be flat when needed, but the original version had "positive-
ground", and some minor changes had to be done

LA3JA later bought the same model, but this had a very bad
intermittent contact in the tuning capacitor, so I couldn't repair it.

DL7QY described a dipmeter covering up to 1GHz, but I haven't really
felt I needed it because it is other ways to check ressonance than
using a GDM, and 1GHz is still not the highest frequency I need to
cover
