Morning Markus - well the transmitters held up well and no issues. The two transmitters and  tx antennae are independent of each other. 475 is a 70ft vertical large top loaded Marconi with 250ft-ish top. The 136kHz is the  standard "Bill" 550ft circumference loop with 60/70ft vertical sections at each end with about 50A loop current. The only difference this year is the 136kHz loops orientation which is now 092/272degT which does not favor Eu (in theory!), and at the moment is a single conductor so a little more lossy - I have physical tree dead and active load  limits here - a bit more flimsy branches than Oklahoma, even so Im effectively "guying" a few of the trees with the antennae wire having around 1200 pound break strain :-)

Both are in the middle of the Boreal forest (100m LMR400 coax runs) which has its issues but for 136kHz its really the only solution that works where I can run a reasonable amount of power and not worry too much about setting it alight,  given the relatively lower voltages on the loop.

475 is a U3 driving the W1VD 500W PA and 136 is a U2 driving the Decca 5501 on two of three modules with 58V both with their own GPS drivers.

Due to construction and tight thermal case the U3 has a little more "drift" during the 15 min tx periods but is tolerable.

  I can still run other tx sources to either PA so will be playing with other modes during winter - Id like to do some of this coherent stuff as I have a reasonable source with the HP3336b/gps available but thats going to take me a search in my cable box for the  serial keying stuff  from a few years back.

Conditions are still "cooling off" iono wise from the recent sol/geomag stuff...and its still physicallt warm here temp wise in Alaska so environmental losses are still higher because of it. I need to build a second Jim M0BMU visual phase/power meter and Ive just love having one of those in line...
