[Elecraft] MFJ HI-Q Loop 1788 Will not stay on frequency.

[Kenneth A. Christiansen]

I do a lot of camping and have used several portable antennas over the 
years. Two weeks ago I bought a MFJ-1788 Super HI-Q Loop. I have been on two 
camping trips with it and it does seem to get out and receive well. I used 
my K2/100 and made 46 contacts for a total of almost 15 hours of operating 
time. My problem is the antenna will not stay on frequency. It will tune on 
any frequency easily but the only time it will stay on frequency is in the 
middle of the night with no wind. I talked to MFJ and Tom recommended I 
tighten the spring on the capacitor. I did and it improved  but again this 
week end I saw it jump and drift. I had it tuned up on 14.058 and it dropped 
down to 14.007. Another time it jumped from 14.058 to 14.076. I know others 
are using this antenna so if you are using it do you have a problem with it 
jumping or drifting around in the band. I have noticed this problem on every 
band except during a cold, clear, calm night. If anyone has been able to fix 
this problem or if my problem is not normal please let me know.

73 and thank you.
