[drakelist] T-4XC will not unkey after warming up

[Larry Groom]

I’ve been using an earlier serial number T-4XC (#21000) and recently after being on for 25-20 mins, the radio will not unkey after transmitting for more than 2-3 mins. I then have to turn the T-4XC off and then back on to get the twins to go back to receive. I’m not using VOX and I have turn the VOX  delay to min but with no luck....   Any ideas?     Thanks Larry
