Same thing with the LDG Tuners, I have tried a few other auto tuners and they all have this kind of problems even if they are connected to a radio that has a "Tune" interface for them like the Kenwood TS-480 or Yaesu's small Radio's if there left in full auto mode.
As Jim suggested just tune them up with 10 to 15 watts then turn off the Full Auto mod and your all set to go. I run my LDG 1000Pro Tuner with my Ameritron AL-80B and it works GREAT using the above setup. The only thing with the LDG tuner's, it just takes a quick button push to make the tuner go between full Auto and Semi-Auto. 73's Bret WX7Y -----Original Message----- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Jim R Sent: Friday, February 20, 2009 11:49 AM To: b...@photinos.com; k9...@rnacs.com Cc: FlexRadioReflector Subject: Re: [Flexradio] external tuner control Bill I have a 998 and yes, when in the full auto mode I have experienced random retuning in the middle of a QSO and sometimes it ends up tuned for a high SWR. To avoid this I just leave the 998 in the semi autotune mode. When I want to tune, I hold the tune button on the 998 in for 2 seconds to arm it for a one time tune and select tune on the 5000 until the 998 completes the cycle, then deselect tune on the 5000. No further action on the 998 is required. Maybe you are already doing this.
