Roger G3XBM’s Amateur Radio Blog: 10m with simple antennas


See on Scoop.itKH6JRM’s Amateur Radio Blog

There is little doubt that when 10m is in the doldrums a beam and QRO would probably be helpful. Every bit of power would help. An HF beam is unlikely to add more than 5-6dB gain (1 S point) so when the band is in good …

Russ Roberts‘s insight:

Another great, to-the-point article from 10 meter expert Roger (G3XBM).  Like Roger, I’ve always believed simple antennas, properly designed and  built, can reap big rewards on problematic bands such as 10 meters.  I still have a few converted CB antennas that work very well on 10 meters once they were  cut to the proper length, had an adequate radial system, and were  elevated approximately 1/2 wavelength above ground.  I agree with Roger that "there are very few times when QRO really matters.  It may help, but it is much more fun with QRP…"  He adds that "QRP can be great fun, especially with simple homemade antennas."  If you prefer a vertical antenna for 10 meters, why not build a simple ground plane antenna using a converted CB whip antenna (108 inches/274.32 cm before trimming) in conjunction with four sloping radials cut to the same length?  You should get a good match for any 50 ohm coaxial cable feed line.  Wire antennas can be educational, cheap, and fun to use.  Aloha de Russ (KH6JRM).

KDØBIK operating as W1AW/Ø | AmateurRadio.com

Colorado’s first week to host the W1AW/Ø portable station in celebration of the ARRL Centennial events has come and gone. This particular week was a busy week for me both at work and in the hobby of amateur radio.

Russ Roberts‘s insight:

A nice recap of Jerry Taylor’s (KD0BIK) role as host of the W1AW/0 portable station in Colorado.  The special callsign has been given to select amateur radio stations to celebrate the centennial of the ARRL. Jerry spent a busy week battling bad weather, maintaining an operating schedule as W1AW/0, presenting two Summits On The Air (SOTA) programs to area ham clubs, and, of course, managing to work at his full-time job.  Despite the pressure, Jerry said "It was a lot of fun!"  Aloha de Russ (KH6JRM).

This past Monday was Memorial Day in the US. A day to remember those who paid the ultimate sacrifice in defense of Freedom and our Country. I am grateful for the dedication and patriotism of these Americans.Memorial Day …

Russ Roberts‘s insight:

A nice Memorial Day tribute from Mike Crownover (AD5A).  As a veteran, I appreciate the kind remarks you’ve given those of us who served our country in both war and peace.  The remainder of the article described Mike’s hectic, but successful mini-SOTA (Summits On The Air) DXpedition to the Ouachita Mountains in Southeast Oklahoma and West-Central Arkansas.  A lot of miles and a lot of contacts….Aloha de Russ (KH6JRM).

Solar indicators continue to weaken. Average daily sunspot numbers declined from 129.4 to 103.3, and average daily solar flux went from 128.5 to 110.3.

Russ Roberts‘s insight:

Here’s the latest propagation analysis and forecast from ARRL propagation expert K7RA.  Look for a slow degradation of solar indicators for the next week.  Hopefully, things will pick up before the ARRL Field Day on 28/29 June 2014.  Aloha de Russ (KH6JRM).

Russ Roberts‘s insight:

Thanks to Mike Terry for this interesting story.  The BBC has introduced a new experimental program service called "BBC Explorer"–a kind of on-demand service for active radio listeners.  All you have to do is "type something that you’re interested in, and the service plays you clips and programmes that it thinks you’ll like."  I tried it for Amateur Radio and got quite a bit of fascinating sound bites and news stories relating to amateur radio.  For details, visit http://www.bbc.co.uk/radio/explorer.  Aloha de Russ (KH6JRM).
