In only a few weeks we will be half way through the VLF season. Is there any interest to try some more experiments? I'm testing on 8820 for the next few hours unless something fails. Dex
Everything here the same as in June except for the oak trees being about 90% bare and a slight bit more inductance needed to go below 9 kHz. Antenna current is 1 amp with a slight bit of wiggle due t
Certainly transmitting - but where is the carrier? Without GPS lock, the HP source should be OCXO stable anyway? Yes. I searched at Forest +/- 0.5Hz now maybe I have found you, 0.1Hz low? The frequen
The frequency was unstable, somewhere around 8819.9970 for a while but it also spent some time near 8819.9985. Paul, Sorry for the wandering signal. This morning I found the signal source was not GPS
With more turns added to the matching transformer secondary I was able to get a bit more antenna current. Will run until 0400UT unless it rains or something fails. Dex
Resend due to error message received: Presently misting rain here and it doesn't look like it's going to get any better today. The antenna current had dropped a few hundred ma so QRT for now. Dex
I've been monitoring near 8820 since Dex's prior transmission (assessing and mitigating noise in case Dex switches on again). Jim, I was testing yesterday afternoon and evening on several frequencies
W4DEX achieved another 'first' recently by sending a series of messages across the Atlantic at 8822 Hz which were successfully copied at Todmorden UK, range 6194km I achieved another first? You can't
Thanks for the XKO capture Henny. The last previous XKO transmission was January 2014. I didn't realize it had been that long. July will be XKO's 10th anniversary. Dex
