Sounds very sensible Hank. :)

Not sure I really understand the question. But if you select the coordinated tx times then you can do what you want until the two mins every 20mins the box is tx’ing the 20m signal. You would probably need to wary about tx’ing close the to the WSPR box feeding it with too much energy from your ft8 signal. I guess you probs guessed all that tho. Mike

Very useful, thanks, my firmware has been a bit behind the times for a while. :)

I don’t recall carriage being that much, just remember if you buy two then you’ll pay 20% of the total plus an admin fee. I’d check to ensure you have understood the carriage costs first.

I think they fall under the limit for customs costs. So only buy one at a time.

I dont recall having to pay customs for my three.

Yes there are plenty of us on here

I have used it above 3:1 with no bad effects

Of course you can try it, but resonance is going to be your problem. So with poor matches on other bands you will see power losses and when only using 200mw these will hsmper your best results. There are multi band EFHW antennas out there which work really well.

EFHW has been working great for me, specially now I have it up a bit higher.

Umm personally for the use of the Zachtek devices I use an antenna analyser which is close to outputting 200mw into the antenna, so sounds like it works to me.

It seems to me that the easiest way to achieve that is to have an off resonant antenna, so use the SWR to do the attenuation for you. Just a thought.

Well mine is outside in all weathers and we have really had some proper downpours this autumn, it’s been fine.

I am no expert but I have recently began using a 60w power supply in preference to my previous 12w ones and whist this is complete overkill it does seem to maintain a stability I never previously had. So I wonder that during the switching bands process that this causes a very short spike in power that lesser power supplies cannot provide and then stop as a result. It’s just a theory and I have no evidence to support this other than my own experiences.
