XG3 6M beacon W7RDP/B on the air

After corresponding with Wayne a little today, I have my XG3 running a
0dBm into a Parr 6M stressed Moxon aimed South at about 45' agl, CN87xo,
just east of Seattle. The frequency set on the XG3 is 50.025MHz, my
K3/10 thinks it is a little lower but not by much. The XG3 is set to
send 5 seconds of 0dBm tone, then W7RDP/B at 15 wpm CW, then 10 seconds
of tone at 0dBm, repeating every 60 seconds.

One thing I found out is to add a word space before the call otherwise
the first letter is truncated, and I added one after just in case.

73, Doug W7RDP

Re: XG3 6M beacon W7RDP/B on the air

Nothing heard yet. How far below 50.025 does your K3 hear it?

I have scanned from 50.020 to 50.030 on both my 6 meter horizontal loop
and on my G5RV. No signals at all except for one birdie.

Re: XG3 6M beacon W7RDP/B on the air

Hello Kevin,

Trust that all is well with you.

It crossed my mind that if your QTH is off the back of Doug's W7RDP/B Moxon
and you are some distance apart, you might not hear his XG3 beacon because
of the large f/b ratio that is typical of a Moxon. For example one of my
wire 40m beams was a Moxon and was back on to Continental Europe (DLs, Is
and such), and its f/b was a good 30ish db depending on the angle of arrival
of the Eu signals.

Also, at 0 dBm power output, his XG3 may only be audible to fairly
close stations unless there's a serious band opening.

Re: XG3 6M beacon W7RDP/B on the air

I should be line of sight to Seattle. I know I am south of it and he is
using a gain antenna. Do you think he will reach beyond the outskirts of
Seattle?

Do we have any experts at path-loss calculations (over typical
Seattlian terrain) on the list?

Re: XG3 6M beacon W7RDP/B on the air

I am at one half the required altitude. Guess I'll wait for reports of Es
and then try again. Now that the frequency is in memory and the loop is
reattached things will go more quickly.

Re: XG3 6M beacon W7RDP/B on the air

In reply to this post by wayne burdick

Not an expert Wayne, but earned my $ calculating path loss at HF up to
microwave during point-to-pont, mobile and relay systems design "back then"
using the classic 4/3 Earth Radius approach at VHF-Microwave. Unfortunately
my relevant data is packed, but I understand that the path between Kevin and
Doug is about 150 miles. So in spite of the elevation of Kevin's QTH, at 50
MHz the path would not appear to be true line of sight but Fresnel Zone
obstructed, which together with any loss added by local obstructions such as
dense tree growth and buildings could put the beacon's signal below Kevin's
noise floor.

I am 18.42 miles NW of the beacon, per Google Earth.
no sig detected yet...but as night falls and band noise drops we might have a chance.
my location is north Seattle between I5 & Hwy99 on 145th
I am at 475 ft asl...7 el LFA at 55ft......K3 of course..........

Dense stands of trees no longer exist on my mountain. Many, many square

I will post this on the PNWVHF reflector and see if we can get some east side guys to take a check.
I would like to know just what the real Freq of the beacon is, I"ll keep a eye out for it using spectran.......

I can detect the beacon using WSJT9, but I can not hear it in the speaker,
The freg I have for zero beat in CW-REV is 50.02576. and I should be close, calibrated w/ sprectran w/WWV

I see a 20 second line on the waterfall every 60 seconds and have been for the last 15 minutes.

my K3 does not have the PR6 preamp.. just using the one in the K3..
