Running on a somewhat traditional set up com port ptt Tx path :: Exciter >> Linear Amp >> Ae change over relay
where the Linera tx line / is addressed from the secondary contacts on the Ae relay , the measured Tx to on-air carrier delay is 52 mS , ptt enable > Rf wondering if this was too long [ days of amtor ] Apparently the Vara HF modem can accommodate up to
120 mS delay
may/may not affect stations using tx/rx sequencing 73-Graham g0nbd
