Joe Tuner works just fine everything is just like a 100 / 200 watt Yaesu is driving the VL-1000 my Quadra is over ten years old and was built when Yaesu had the company it is the second version I want to say of the original released.
I use the K3 [TUNE] button for tuning the tuner and band changing, I do not change the power level. I put the amp out put into a dummy load then use the [F-set] button and [TUNE] on the K3 the amp will change bands using this method with anything over 50 watts or so. One of these days I will do up a band data cable for the band selection of the Quadra. The Quadra has worked flawless from day one.The switching power supply has been on all these years with out a hitch. I hear the maintenance feature exercising the relays in the middle of the night regularly.
