It's amazing, I can tune up to anything with this thing, it's incredible. My only concern is radiating efficiently. I remember hearing that you can put a metal spike into a tree and use the tree as a radiator.

The best you can do is really based on the amount of space you have, if you can fit half wave elements, that will obviously be the most efficient while also keeping the 50 ohm coax happy.
 
Ah screw it, I'll just cut a 10m length of my christmas tree lights wire and do an EFHW. I wonder if I should even bother with a balun if the G90 can tune up to it, it'd just be losses at that point.
I'll find out at the JS8 activation! I'll bring the dipole setup too so I can at least listen in in the EFHW is a bust.

I don't have my yubikey with me or good enough cell service to log in to post to the thread. A quick update to the JS8 bulletin for 3/07:
- I haven't been able to spot myself on 20 meters and only get a handful of pskreport logs on the 16:00 UTC window. But around 18:00 hrs it starts to open up. I will still be transmitting the bulletin at that time, but I'm adding another additional time slot at 01:00 UTC. So the new schedule is as followed:
- 16:00 UTC - tx1
- 23:00 UTC - tx2
- 01:00 UTC - tx3
The best options to listen will be at 23:00 UTC and 01:00 UTC. (Also remember if you are listening from the US, your timezone is likely daylight standards time. So 01:00 is 21:00, 9 PM EDT) 
tx2 and tx3 will be the best listening options due to propagation conditions
Also make sure your receiver is set to 2400 Hz bandwidth, USB. Same 14085 kHz frequency Thanks!

Are you in contact with him over the air?

So I set gqrx (using a rtl-sdr dongle) to 14085 USB and js8call to 1500Hz offset?
Presiona para expandir...
The offset is automatic, I'm pretty sure, looka good to me.
I say you should test it on USB 14078 to see if you can catch normal JS8CALL traffic. People have heartbeats going on there all day
 
Approximately 3 hours to KiwiNet on JS8Call.
I'll be verifying band conditions and traffic conditions 30 min beforehand. Unless it just looks cooked, plan on using the configuration @888Flux has posted already from the last time we tried this. Reread the set up instructions again just to be sure. This is a shake off run so let's all expect some hiccups. If 1-3 other kiwis recieve its a success. If 1-3 other kiwis also retransmit? Astounding victory.

What to expect: a welcome message, repeated 3 times, 2 min of down time to allow anyone transmitting to respond. And then 2 minutes after the last response (if any are recieved) the first item of note. And another 2 minute pause. Then the next and so forth. Till the end where I'll request any news I didn't share.

The breaks are for retranmissions and for my transmitter to cool off. If I start seeing thermal issues I will let you know I'm pushing the pauses to 5 minutes. Last time I hammered it out at one time it didn't do well.
I dragged everything to work with me because they just couldn't bear to give everyone a day off today so they can pay me to play around with my radio.
 
I'm receiving a schedule broadcast on 14085 right now, matches the one in the post, glad I left it running! Low strength though so It keeps getting mangled.
Heard on offset 1771 using slow mode

I missed the 1600 time slot because of work bullshit.
I just tuned in now at the home QTH and saw this on the KF freq. Who ever 888AO is I C U

My client says 888 is using 1776 Hz offset, very tasteful. I am amazed by JS8CALL's ability to pick out the faintest signals that I can't even see in the waterfall, though the cost of that is having schizophrenic messages come up from background noise.

Isn't it 1600 UTC only in ten minutes or so? We've started already?

ya I am retarded. I messed up the savings time conversion in my head. I should have tuned in to WWV before posting

If thats 888 and he is +9/+10db to me then i am going to try going mobile and picking him up with the hamstick and then my old DX440's whip on the next timeslots

Someone else who is very weak to me is trying something but their clock is off.
SYNC YOUR PC CLOCK WITH NTP ⏰

ITS HAPPENING

I'm so felted. Windows JS8Call just stopped working, I'm desperately trying to get my arch laptop working with it and it's being arch.
 
Can't even pick up 20 meter FT8 here, it's that bad for RX for me at the moment. Trying to sort out TX issues. 1600 is probably a bust but I should be able to get things figured out by the 2300 slot.
 
FT8 on 20M is nice and busy here but no JS8 decodes on 14085kHz at my QTH. Hopefully have better results after the ionosphere clears the solar wind.
