 Now that I'm turning my attention back to QRP I decided that the antenna I've used for many years - an Inverted-L held up by (over the years) different supports, and currently a 10m SOTA-pole with the top few sections removed - tuned against a mess of radials and ground rods by a CG-3000 Auto-ATU - was due for a change. Now that I'm turning my attention back to QRP I decided that the antenna I've used for many years - an Inverted-L held up by (over the years) different supports, and currently a 10m SOTA-pole with the top few sections removed - tuned against a mess of radials and ground rods by a CG-3000 Auto-ATU - was due for a change.

 The Auto-ATU needs "a few watts" to trigger a re-tune on a new frequency. Occasionally it'll work with 5W but not consistently, and certainly won't re-tune at anything lower than 5W. This means occasionally having to give it a carrier from a QRO radio to re-tune before switching to a QRP radio.  The Auto-ATU needs "a few watts" to trigger a re-tune on a new frequency.
