TR on 6926
« on: April 12, 2011, 0054 UTC »
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.

 :D 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.

 8) 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.
