Powerpole voltage and current monitoring is quite nice to have. One can buy commercial meters, but due to the availability of nice and cheap modules, it is very easy to make them oneself.

To the right you’ll see my combined voltage and current meter as well as my volt-meter on top of the power supply.

Both of the modules have been bought on Ebay:

• Miniature 0-30 V DC LED 2 wire Digital voltmeter (371333527599) where the display is 22 by 10 mm. Cost slightly more than $1

• 0-100 V, 0-10 A Dual Voltmeter Ammeter (262455987311) costing less than $3. The module size is 48 x 29 x 26 mm and the letters are 7 mm tall just like the miniature voltage display.

I have “a friend” that could probably use this.

Well, here we are once again trying to get the portable ham radio setup going.

My first attempt was to place one of my mono band whips on my bike and set out a counter poise. It was with mixed results, the SWR was sometimes all over, there was a TX error message now and again on my KX3 and basically frustration trying to get it to work. So if at first you don’t succeed try try again.

Last week I was online searching again for another way to get my portable op’s on the air. I was looking for something that was easy to deploy, was portable and worked!

My interest has gone toward the Endfed  antennas. I was looking at LNR’s antennas and then I came across the Endfed 40-6m antenna by Steve W1SFR. I shot him some questions regarding the antenna and he got back to me right away with the answers. His Endfed seems to be very well built using Wireman “silky” 18 gauge wire which I have used in the past and been very happy with. There was a nice noticeable quality in both the wire connections and the 9:1 unUn.

The antenna is only 35 feet but you do need about 25 feet of coax to act as a counter poise. Also your rig needs to have an antenna tuner (mine does) to get the benefit of 6m-40m with only a 35′ antenna and no traps. Also it was nice to see on his web site a link to purchase his antenna including shipping to VE3 land.

The shipping was super reasonable the total came to 67.00 U.S. Steve also mentions that his price includes handling as well. Other sites I had gone to being very interested in their antenna to only find out the shipping at times was either 1/2 or more of the price of the antenna.

There was lots of positive reviews on Eham about Steve’s antenna  as well. I put some items I am not using in the shack sold them very fast and the funds were in place so I have placed my order and waiting for it to arrive.

I have the 25′ of coax on hand but I do have to head out to the hardware store for some rope 1/8″ nylon rope. Then I’m thinking of placing a water bottle with some sand it it as a weight to get the rope up and over a tree branch…..that is going to take some practice!

that next Monday, June 20th, is the first day of Summer. And you know what that means ..... Skeeter numbers will start to be issued that day!

Beginning this year, the Hunt has been moved to the third Sunday in August in order to even out spacing a bit between FOBB, the Skeeter Hunt and the NoGA Peanut Power Classic.  Also, there are some rule changes for 2016 in order to more fully incorporate NPOTA into the Skeeter Hunt. Make sure to check them out at www.qsl.net/w2lj.

Here is this week’s space weather and geophysical report, issued 2016 Jun 13 0444 UTC.

Highlights of Solar and Geomagnetic Activity 06 – 12 June 2016

Solar activity was at very low levels from 06-08 June and again on 10 June. Low levels were reached on 09 June and again from 11-12 June due to C-class flare activity from Region 2552 (N15, L=359, class/area Dao/150 on 11 June). The largest flare of the period was a C6 at 11/2228 UTC. Region 2552 grew rapidly since its emergence on 07 June to a compact beta-delta magnetic class, but appeared to be in decay by 11 Jun as it neared the NW limb. No Earth-directed coronal mass ejections were observed during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels on 06 June and again from 11-12 June. High levels were reached from 07-10 June with a peak flux of 1,590 pfu observed at 10/1520 UTC.

Geomagnetic field activity ranged from quiet to G2-Moderate geomagnetic storm levels during the period. The period began with solar wind speeds near 650 km/s and total field values near 7 nT while the Bz component fluctuated between +/- 6 nT under the slowly waning influence of a negative polarity coronal hole high speed stream (CH HSS). As a result, mostly active levels and an isolated G2-Moderate storm period were observed during the first half of the UTC day on 06 June. Solar wind speeds continued to decrease to nominal levels by 10 June. Quiet to unsettled conditions were observed on 07 June with quiet conditions on 08-09 June. By midday on 10 June, a solar sector boundary crossing was observed into a positive (away) sector followed by an increase in total field to 14 nT by late on 10 June. A lesser rise in solar wind speed to near 540 km/s was observed as a positive polarity CH HSS moved into a geoeffective position. Solar wind speeds continued to be elevated in the 450 km/s to 550 km/s range for the rest of the period with total field ranging between 7-10 nT. The geomagnetic field responded with quiet to active periods on 10-11 June and quiet to unsettled levels on 12 June.

Forecast of Solar and Geomagnetic Activity 13 June – 09 July 2016

Solar activity is expected to be at very low to low levels for the forecast period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at high levels on 17-18 June, 26 June-01 July and 04-07 July in response to CH HSS activity.

The geomagnetic field is expected to be at unsettled to active levels on 13, 15-17, 22-24, 26-27 June and from 02-03, 07-09 July with G1-Minor storming likely on 02-03 July due to recurrent CH HSS activity.
