Having read some reviews of the Eton G3 I have found out that some of the early units suffer from poor ssb sync using the built in sync function. My G3 is a very early (sub 300 serial number) unit although I only purchaced it a few weeks back.
It seem to suffer from the poor ssb sync as demonstrated in this video of Volmet on 5.505 USB shows. The first few seconds is Volmet tunes in manually and all sound fine. Then I turn on the sync feature and it all goes a bit wrong!
I have emailed Eton regarding the problem and they have advised me to send the unit back to the Uk distributor (Nevada Radio) for a replacement. I’ve just emailed Nevada so lets see what they say..
