[TowerTalk] Old Mosley PRO 37

[Yuri]

Hi
Just arrived to Zone 2 for the Contest and found Mosley Beam having high SWR 
(~ 4) on 20 m.
Other bands (15 and 10 seem to be Okay, however the bandwidth is 
suspiciously wide on 15 (over 400 kHz up down from the resonant frequency).
The antenna analyzer shows perfect resonance around 12 MHz with good SWR 100 
kHz up and down.
Any idea what could happen?
The visual inspection did not show anything suspicious.
Thanks.
