Equipment / Up the discone!!
« on: May 15, 2020, 0010 UTC »
Today I started my little project to get some elevation on my DJ-130 discone.  Itís been mounted on a 2nd floor deck, but I want to try and raise it above the roofline if possible.

Its new home will be a tree so I broke out the fishing pole, lead sinker, and slingshot. I was pleasantly surprised to manage to get the line on a decent branch without the lead sinker breaking any windows or heads.  So far so good....

Next was to swap the 20lb test for something more substantial.  Unfortunately the 550 cord I thought I had was nowhere to be found beyond bits and pieces, but nowhere near the length necessary.  Amazon to the rescue, but that means itís in a holding pattern for now.

Maybe CW?  Broadcast on 7335 and 7365 kHz 20191116 0216 UTC until ?????.  Captured from central MD, but also noted on Kiwis across eastern US (didn't check western US).  TDoA suggested SE US, maybe Florida....

Someone on HF chat commented that these are Radio Marti freqs.....

HF Mystery Signals / UNID pips ~ 14220kHz 1337 UTC 7 June 2019
« on: June 08, 2019, 1806 UTC »
These came up at multiple frequencies (although I don't recall if they were concurrent) on the morning of 7 June.  Interesting thing is the train on a frequency would cycle up in magnitude and back down again....maybe a directional antenna sweeping around?
