The 2m dipole attachment I made for my monopod seems to be working well. It’s a definite improvement over the Diamond SRH77CA and SRH999 antennas (which already work fairly well) when it comes to receive. I can receive a pretty clear signal from the repeaters from inside the house, whereas with the Diamond antennas, the repeater signal was on the scratchy and noisy side. When I’m outside, all of the antennas perform pretty well.
The two repeaters closest to the house that I can reach (and use) are about 7-8 miles away, so they’re a bit of a reach to hit standing on the ground with a 5W HT. The repeater beeps at me after I transmit, so I think I’m hitting the repeater with the dipole attachment, although I’m not sure how well I’m getting in. The repeater has a voice playback function, but I still need to learn how to use it.
In any case, the dipole attachment seems to be a success, and I can at least monitor some of the repeater activity more easily.
Time to start planning for a dual band VHF/UHF radio for the house.
US amateur radio operators will soon have access to small slivers of the 630 m and 2200 m bands as secondary users. The 630 meter allocation goes from 472-479 kHz (a little bit below the US AM broadcast band, 530 – 1700 kHz) while the 2200 meter allocation goes from 135.7-137.8 kHz (not a heck of a lot).
Before being allowed to operate, hams will be required to notify the Utilities Technology Council. Notification can be done online, and involves submitting name, contact info, call sign, lat/long of your antenna location(s) and the bands you’re planning on operating on. If you don’t hear anything back within 30 days, you’re supposedly good to go.
Even if you have no immediate plans to operate on the new bands, you might still want to notify the UTC in case you decide to operate there later. If there’s no objection to your notification, and a utility later wants to deploy or modify a PLC system near you, they’ll have to use a frequency range other than one you’ve indicated on your notification.
If an electric utility seeks to deploy a new or modified PLC system on a transmission line that is within one kilometer of a previously coordinated amateur station, the electric utility must employ a frequency in the 9-490 kHz range that has not been included in the amateur station’s notification, as ARRL suggests. If the previously coordinated amateur station no longer operates in the band, the electric utility may deploy a PLC system in that band.
As expected, all the TN stations I was able to hear were on 40 m. Made a few more contacts than I did last time, but I think more counties this time. Wasn’t able to find the bonus station though.
Band QSOs Pts Mul Pt/Q

Total 27 81 21 3.0
1 Mult = 1.3 Q's
Wasn’t hearing a whole lot of activity across the bands in general, but the 40m shortwave broadcast stations that usually show up in the upper portion of 40m late afternoon/early evening seemed extra loud when they appeared.
It’s nice having the shack back up and running, even if setting up and taking down the antenna means it takes a little more time to get set up.
Got the antenna up this weekend to participate in a couple of events. It’s the first significant amount of radio activity I’ve done at the house since moving from the old house.
On Saturday I spent a few hours tuning around the bands working the NAQP SSB contest. Managed a couple dozen contacts casually spinning the dial around on 20 m and 40 m.
On eclipse day, I managed to get a few contacts in the Solar Eclipse QSO Party in the morning. Didn’t hear too many stations on 20m, but there were a few. I heard a couple of stations out in Washington State, but couldn’t get through the pileup they had going. Made contacts with three other stations participating in the eclipse QSO party and made periodic checks on the WWV broadcasts (heard 10 MHz faintly at times, but 15 MHz was coming in loud and clear).
A while back, I made a monopod to use with my camera. Handy thing to use when I don’t feel like lugging around a tripod. Also serves as a nice walking stick.
On one of my last visits to Radio Shack, I picked up two telescoping antennas thinking that I could use them as dipole elements.
Add one section of aluminum angle stock, a bulkhead BNC jack, a couple 1/2″ 4-40 screws and nuts and now I’ve got a telescoping 2m dipole antenna attachment for the monopod.
It took me a while to figure out how I was going to insulate one of the telescoping elements from the angle stock. While I was studying the problem, a solution struck me: plastic wall anchor. Worked perfectly.
Tuning the antenna was a simple matter of adjusting the length of each telescoping antenna to get close to 1:1 across the 2m band.
Looks pretty good. I’ll check it again outside over the weekend and try it out with the HT.
If I hold it up in the air by the base of the pole, I can get the antenna about 2.5 m up in the air. I’m hoping I’ll be able to reach the two repeaters that are about 8 miles away a little better than I can with the HT antennas I already have.
