30m beacon on the air


"pgdaulton"
 

I braved the 100 degree temp today and got my beacon up on the air at about 2230utc(630pm cdt). Freq is about 10.140070 with some instability due to high temp.

Beacon is mounted in plastic box at center of dipole. Tx power into a resistive dummy load was 80mw(2volts peak to peak). 5volts dc power is run up to tx through rg59 cable tv coax.

Reports welcome.

Hi Paul,

10.140010mc is what I just seen on your signal.

MIke send me a capture, you are my first report.
?
I see my base line at 10.140035 right now at 930pm cdt. Freq moved around until it got heat soaked and then it settled down.Just got back from Wallyworld, themp on bank sign downtown was 85 degrees at 9pm. heat index still probably at 100, very high humidity.
?
I?have a new battery for my lowfer beacon, on charger now will install it tomorrow.

Have a look. You are in there just slightly below 10.140000mc. The top of the signal is at 10.140002mc right now. It moves up & down as time goes on. I am going to install a crystal heater in mine.

Only 64F up here today. Been cold for many days.

Mike,
?
I finally see my k0nwt on your grabber - a bit low this a.m. - at 10.13995
?
I will adjust tonight when I get home from work. I'm in the EM73ut grid.

Hi Newt

I think I see you on at 10,139,920 / 10,139,950. Massive 30Hz wide FSK CW ;-) As well as adjusting a bit in the upwards direction, you probably want to snip a bit off the "gimmick" capacitor, so that the amount of shift comes down to a more reasonable 4 or 5 Hz.

Very hard to figure out the message with his signal being so wide. Looks like my Grabber is running fine. Calibration is within 1hz calibrated to 10mc WWV signal daily.

Hans and group,

Sorry about taking up so much bandwidth!! - I will lop off another bit of the trick cap this evening when I get home. I will target 5 Hz for my FSK CW.

I cut off a bit of the 'gimmick' cap and adjusted the signal to ride between 140077 and 140082 according to the WE0H grabber. Thanks Mike - I did my adjustment this evening using your grabber as reference. I will add 4 'C' cells tomorrow night? to my margarine tub beacon before I leave for my overseas trip.

Hi Newt,

Cool, glad the Grabber is of use. When your signal comes in here it is strong. I see it is gone right now but I'll watch as the night grows older...I will test and calibrate my Grabber daily so it should always be within 1hz accuracy. Plans are to build a DC receiver with a crystal heater and put a remote Grabber 40 miles from here out in the country. It will be a very quiet location. Calibration testing on this second remote Grabber will be once a month so hope the crystal heater does it's job and keeps it on freq. hi hi...
