Tune Button on W0ZSW

The Tune button on the W0ZSW remote interface is now available to transmit privilege users.  It works through the Windows PC and Android apps, activating the LDG automatic antenna tuner to match the impedance of the 270 foot dipole fed with 450 ohm ladder line to the Icom IC-7200 transceiver.  When the tuning sequence is activated, you will not hear the receiver until the cycle completes.  At that point, the signals should be coming in even better, since the antenna is now tuned.  Often tuning the antenna will make the difference between hearing nothing on a given band and the band coming alive with many signals.  Always identify your transmissions.

Sometimes you will encounter a frequency where the LDG tuner has not already “memorized” the tuner settings.  When you toggle the tune button, it may then take 20 to 25 seconds to go through the whole tuning sequence as the LDG tuner tries one combination after another to get the best match.  During this time the receiver will be silent, but when it is complete you will once again hear audio.  Then you can identify and go ahead and operate.

Please email wa0tda@arrl.net to report any problems.  Have fun with the radio!
