TR on 6926

[Token]

Howdy all,

The transient beacon "TR" that normally shows up around 4060 kHz is currently on 6926.1 kHz.  Been there for the past couple hours and fairly strong.

  The TR beacon in the Northern Mojave Desert runs occasionally.  The ant. was shortened for 43m beacon signals in March 2011.  It is 100 mW. Inverted-vee.

VFO is jfet osc. to 2n3866 buffer to NTE-295 power amp. NPN -class-C p.a. (?) - forget final amp. exact number - anyway,  it is on 6930 kHz tonight past midnight PDT for Memorial Day transmission.

It can be put in a very FM-ey "AM" mode as well for low-power broadcasting to local desert on hikes.

I have a recording of that FM-ey AM mode around here someplace, both on 4060'ish and 6926.1.  I think it was up in AM earliier the same evening I made this video of it in CW mode: http://www.youtube.com/watch?v=1wDmTGZBoN8

That's a very nice video, Token, you made of reception on April 11th - I had no way of knowing it was getting out so well for about 100 mW.

  With the recent increase in solar-activity and higher MUF's on HF in the daytime now, it was decided to put this beacon back in the 6.9 MHz region rather than down on 4.0 - 4.1 Mhz region.  It usually runs when I go on trips to DX it from various locations, like nor. CA or other desert locations, etc.  The VFO mode (in an old BC-221 enclosure using that unit's var. cap and switches but with all else gutted) make for the chirp, but that is a fun charcteristic of TR. The ident came from an old Medfer beacon used in the late 80's(!)

Token, looks like you have a very excellent DX set-up in the desert! Your vids on YouTube excellent, as is your receiver - many thanks!

TR will occ. run about 6930 kHz or a tad higher so as to not QRM too badly 6925 USB xmssions.
