"Peter Bent" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Thanks Grant.. I will try the removal of the pilot lamp. Actually, as I told Bob, I "mistyped" Kilohertz for Hertz... so in fact the drift is 100 Hertz after 45 minutes..

The heat from this lamp is a known cause of warmup drift. There is also a "blue led" replacement module (http://home.wi.rr.com/n9oo/products/tr7lamp/d7lamp.html) for both the meter and VFO lamps, which does not generate the heat of the incandescant bulb and also solves the "where do I find blue filters" problem. I don't think the 1 Khz up/down drifting around after warmup is at all normal.
