Bob:
We've had an ECO-10 and ECO-30 for several years and are currently operating the ECO-10. It does have a remote reset feature. It can also be done manually from the front panel.
I'd would suggest not having it reset with the "power-on." The overload circuit is one step in the start-up chain of events and if an overload condition occurs, it will shut of the plates, IPA, and mute the exciter. Or if the overload is activated, the transmitter will only come up to that point (just fans, air-pressure interlock, filaments, delay, door interlock, etc.) and stop.
If you sort of defeat the overload by resetting with powering on, you lose some information that might be useful when operating the transmitter remotely and maybe risk damaging other components. For instance, a few weeks back we had a tube lose vacuum and the transmitter had an overload (current overload) and shut down. We did not know that at the time, just that we were off the air. Tried to shut down and restart remotely - nothing. Then after trying to operate normally, hitting the reset remotely. With the tube with no vacuum, the transmitter would start to power up and when the plates and some RF drive was applied, back to overload but in the process would cause a lot of the other equipment (like the SINE remote control that I was dialed into, the DSL, etc.) to reset or go offline from the power fluctuation that it would cause before the overload protection kicked in. From having seen this happen in the past with a "gassy" tube (seeing the building lights flicker, etc.) we quickly figured out that there was a tube problem and the overload protection was being activated. A visit to the site allowed us to test the HV plate without a tube and then replace the tube with a standby. You need to keep the reset and power-on seperate.
We had an antenna problem a few years back operating the ECO-30 and it does have a fold-back which limit output with increased VSWR. This is adjustable. Contact Bernie Wise.
