I seem to have some problems with my 3 day old 6600M but I hope it is down to something I am doing (or not doing).
Using either VFO knob and quickly scrolling across the band I experience a marked degree of ‘overshoot’ rather like backlash in very old radios. If I stop tuning rapidly to home in on a station the VFO keeps going (overshooting) so I have to tune in the reverse direction to accurately tune the station, sometimes going back and forwards a couple of times to do so.
At one point it seemed to work well on 20m SSB but not on other bands. I did a factory reset as per the manual and now even 20m has the same problem. It is independent of modes (SSB, DIGU, etc). I then downgraded from 2.3.9 to v2.3.7 but no change. Reverted to 2.3.9. It makes operating difficult as rapidly scrolling across the band then attempting to tune a station is a tedious process.
Another thing is that when switched on the radio used to take me to a screen asking which software version I wanted to load. Now it goes straight into the last loaded version. Although I actually prefer this I cannot explain what has caused it to change.
Yet another thing: after normal power down I switched off the DC supply and removed the PowerPole connector for several minutes. Applying power again all the control backlights came on and stayed on even before I pressed the radio’s power switch. After booting up then powering down again the backlights remain off. This doesn’t seem repeatable and only happened the once.
Regarding a reset to factory defaults, the function buttons retain the customisations I made. Not a problem at all but I would have thought ‘factory reset’ set everything back to the ‘out of the box’ setup?
Another issue is that I am unhappy with the VFO A tuning knob as when spun quickly there is a faint scraping noise.
Any thoughts on the above?
