QRO - 1 Watt WSPR on 40m

Just took down the 1 Watt 40m WSPR into a 1/4 Vertical with 8 Radials.    I had been up for  a couple of weeks now and have learned a few things mainly that the Antenna performs better in the W SW direction vs the E NE direction.  The Antenna's Ground Plane is tiled so towards the South Pacific the throw angle is lower then the theoretical 30 degrees  and towards Europe it elevated.     So I would like to build the same antenna on the opposite side of the hill favoring Europe!     There is just one tiny little problem its about 600 ft from the Ham Shack.     I do however have a solution and its called " LDF4"   I have a ton of it that was discarded from where I work the only problem is that its in 200 ft chunks but again I have a plan!   Connectors are expensive and ackward but I have a plan to splice the cables together .... again I have a plan!


So here are the results on 40m for the past 2 weeks.....

Top 10 ....



















There were 481 unique spots ...













































I was comparing my WSPR to a local ham VA3UAL.    He was running 3 db less then me at 500 mw and I have no idea what Antenna he is using but he had better SNR into Europe and I had better SNR into the American SW and the South Pacific ....this more or less proved my suspicion about the hill!

Sotabeams recently added a new feature  that allowed some pretty good comparisons.   This will be particularly good when I am comparing 2 antennas at my QTH.





















CF3UAL performs 0.43 db better  then I do overall.    UAL get to Europe better then me and I get towards the South Pacific better then him!   When propagation is open to Europe the number grows to oa 4 db difference in favour of UAL and when its open towards the W SW I do about 4 db better the UAL!


1 mw 48 hour WSPR

Had to shut it down today because of power interruptions and the threat of T Storms.

Ran a 1 mw WSPR on 30m into the 1/4 Vertical with 8 Radials,  here are the results......




















 When the weather improves I am going to fire it back up and drop the power another 3db to 500 micro-watts!

 How low can you go?

Contacts 2 and 3 on the new Fan Dipole

Signals were weak but I had a 15m CW QSO with a fellow in New Zealand.  Mexico to but he was a 59.  I was expecting the Central and South America opening but not NZ at 254 degrees the antenna isn't optimized in that direction!

15, 10 and 6 Meter Fan Dipole

I have just about completed the fan  dipole for 15, 10 and 6 meters.   I haven't had an antenna on 10 and 15 since last fall and I have never operated on 6 meters.     There was quite a bit of fussing to get teh design down  but I think I have the final configuration in place and have it reasonably tuned.    The antenna is up about 30 feet and runs in an East - West direction.     I need to replace the string with Antenna Rope and may add a counterweight for tree swing or I may just leave enough slack for the movement.  

Tuning as of this post ....
Freq     VSWR 
21.0 -  1.4:1
21.2 - 1:1
21.45 - 1:1 

28.0 - 2.2:1
28.5 - 1.5:1
29.0 - 1.2 :1 
29.5 - 2:1
29.7 - 2.1:1

50.0 - 1.6:1
50.4 - 1:1
50.8 - 1.4:1
51.2 -  2.3:1

Looks to be tuned about right....low end of 10 is  a bit high but the rigs antenna tuner should take care of the match quiet nicely.  

First contact with this antenna was on 15m

CF3UAL vs VE3LDP

 I am TXing a 1 Watt WSPR into a 1/4 Vertical with 8 Radials.  CF3UAL is in my Grid Square TXing a  0.5 Watt WSPR.  I don't know what antenna he is using so there is some unknowns when it comes  to comparing the results.

 My Antenna's Radials are tilted up towards the ENE and down towards the WSW.      With a more or less perfect ground plane the 1/4 Vertical has about a 30 deg throw.    There is no doubt that towards Europe I am somewhat above 30 deg in elevation and towards Australia I am somewhat below 30 deg.    I built the 80m Vert at the top of the hill to have a ground plane that went down towards the , E , W and S but is level towards the N.   The 80m antenna works really well getting to Europe!  

I would put all my antennas up the top of the hill but three is one little problem ,  its a 500' run on coax!   I am currently using LDF4 which has almost Zero loss at HF.


So here it is ..." Simultaneous Spots"  from 6:30 pm est until 12:30 am est.   Sunset was at 8:41 pm est.     Basically propagation is open East......

Spots: VE3LDP vs CF3UAL - 7 MHz















As you can see CF3UAL is 3.6 db higher towards Europe the I am.  Based on the reported power it should be the other way around.



Sunrise this morning was at 06:02 am est.   The chart below is from about 01:30 until 07:30 est time.

Spots: VE3LDP vs CF3UAL - 7 MHz



















With propagation open towards the West I am 4.5 db higher then CF3UAL.

40m WSPR

 Running a 1 Watt 40m WSPR into a 1/4 Vertical with 8 Radials.  The Antenna is just up behind the house with a gp tilted towards the sw.

 Started the WSPR around 5pm est today about 4 hours ago.  Best result would be the long path to Australia ,  21947.0 km!
