Squelch delay
During operation, received signal strength often fluctuates.
This can result in annoying repeated opening and closing of
the squelch during reception of the same signal. The IC-207H
has a built-in squelch delay function which helps prevent this.
When both stations are operating from a fixed location, this
function should be set to “short” e.g. packet operation.
➀Push [PWR] to turn power OFF.

mode.

source of the problem if possible, and replace the damaged
fuse with a new, rated one (FGB 20 A) as shown in the dia-
gram below.

If you want to initialize the operating conditions without clear-
ing the memory contents, etc., a partial reset function is avail-

14OTHER FUNCTIONS 66 DAdjusting the transmit signal output from the TNC When setting data transmission speed to 9600 bps, the DATA signal coming from the TNC is applied exclusively to the in- ternal limiter circuitry to automatically maintain band width. NEVER apply data levels from the TNC of over 0.6 Vp-p, oth- erwise the transceiver will not be able to maintain the band width and may possibly interfere with other stations. 1. When using a level meter or synchroscope, adjust the TX audio output level ( DATA INlevel) from the TNC as follows. 0.4 Vp-p (0.2 Vrms): recommended level 0.2 Vp-p–0.5 Vp-p (0.1 Vrms–0.25 Vrms): acceptable level 2. When NOT using a measuring device. qConnect the IC-207H to a TNC. wEnter a test mode (“CAL”, etc.) on the TNC, then transmit some test data. eWhen the transceiver fails to transmit the test data or transmits sporadically (TX indicator doesn’t appear or flashes): Decrease the TNC output level until the transmit indicator lights continuously. When transmission is not successful even though the TX indicator lights continuously: Increase the TNC output level.
