Hello, I am considering the purchase of the KAT500 Tuner. I am driving a restored Heathkit SB 200 with my K3. Currently have a manual tuner. Are there any concerns or comments with replacing the manual tuner with the KAT500? Thanks. I would be grateful for any feedback 73, Ron, K5HM k5hm.ron at gmail.com www.qrz.com/db/k5hm
