Hi All,
I am the proud owner of a General Grant mobile radio, but it has a problem.
On USB, every time I key the mic there is about a 1 to 2 second delay before the radio transmits at full power.
Any ideas?
For the first 1 to 2 seconds of every mic key, the S-meter does not move, and there is hardly any RF output.
Relay that needs adjusting?
Please help Thanks. |

On SSB, there should be no "swing" or movement of the meter needle until modulation begans.
Does it move to show output when you modulate?

Hi Capt, as described there is a delay on TX only on SSB - if I key the mic and whistle into it straight away the radio should TX and the s-meter should move with my whisles or voice peaks as it does in all my radios. This radio, the Grant there is a delay of 1-2 seconds every time I tx on SSB.
The grant has a built in amplifier - it is as if the amplifier has been adjusted to have a SSB delay and that it needs re-adjusting to stop the delay - however, as far as I know this is not possible as the amp has no adjustments...
Any ideas please?? |

does the length of delay change if you lower power? never diagnosed that type of problem in a built-in amp, but there has to be SOMETHING to delay SSB from unkeying too soon, probably a capacitor. i've seen the OPPOSITE problem-a delay in 'receive' or actually 'unkey'-if an SSB station keys quick after you unkey, he gets cut off. try contacting GRTS on this forum or call galaxy service & describe the problem as 'IN A GALAXY 95t', NOT a general grant. they may have some info for the 95-they ARE the same radio. |
