Amateur Radio Parity Act… Amendments?

On February 11, the House Subcommittee on Communications and Technology (chaired by Greg Walden W7EQI) voted to send HR 1301, the Amateur Radio Parity Act, forward to the full Energy & Commerce Committee. Yay! A major step, because if they’d voted it down, it would have been toast for this session (and maybe forever, if it got beat bad enough).

They passed it on a voice vote, and it appeared to be unanimous. Also Yay!

But hold on. There was one Committee member, Rep. Anna Eschoo from California, who has been wary of, if not opposed to the bill, based on lobbying she’s received from an association of HOAs (the CAI – Community Associations Institute). Her comments in the session, and those of Chairman Greg Walden and the bill’s Sponsor, Rep. Adam Kinzinger of Illinois, all referenced the need to compromise on some amendments before the bill arrives at the parent committee, and noted that there hadn’t been time to prepare new language for this “markup session” (when a bill is voted up or down).

I don’t know who’s involved in the negotiations. They’ll certainly involve the Representatives and their staffs, and probably the ARRL and CAI.

I do have a clue about what they’ll be negotiating, though. At a January 12 hearing, both ARRL and CAI filed letters with the Subcommittee, although neither group had anyone testifying in person or answering questions. The CAI’s letter contained 7 specific amendments they requested. I marked up their document with some highlighting and comments (but didn’t change or delete any of their text), and you can see it here.

So the list of amendments had been hanging around for a month, but the Subcommittee didn’t get to them before the markup session. That’s too bad, I guess. Might have been interesting to see the points discussed or debated in the Subcommittee. Instead, the discussion won’t see a lot of sunshine until the result surfaces, possibly in the full Committee. (I will be asking some questions before then. Answers?)

Here in HamRadioNow Episode 245, I’ve got video clips of the markup vote and comments by all the principles, and clips of all the Parity Act discussion from the January hearing. And I review the CAI’s document and discuss the amendments.

‘Ham Talk LIVE!’ weekly call-in show debuts Thursday, February 18

neil-rapp-wb9vpgNeil Rapp, WB9VPG, is taking to the Internet airwaves Thursday, February 18th at 9:00 pm Eastern (02:00 UTC) with a brand new live call-in podcast. Ham Talk LIVE! will feature general interest ham radio topics and special guests with a wide range of ham radio expertise.

Unlike traditional ham radio podcasts, Rapp says he hopes to create something a little different. “I really look forward to just doing some open line shows,” he says. “I want it to be a conversation and just talk about happenings more than just disseminating information. We already have people doing a great job with that, and I enjoy watching and listening to them.”

Thursday night’s episode will discuss DXing and contesting and will feature well-known DXer Dr. Scott Wright, KØMD. Next week he’ll host popular Amateur Radio Newsline anchor Don Wilbanks, AE5DW.

ham-talk-live-schedule

To tune into the show, you can visit HamTalkLive.com. To participate, listeners can either call Skype username ‘hamtalklive’ or dial (812) 638-4261. “I don’t have a call screener. Once I answer they will be on immediately so I won’t answer until I’m ready for the caller,” Rapp says.

The show will last 30 minutes each week. If listeners miss the live show, a downloadable podcast will be available on iTunes, Spreaker, and possibly other outlets soon after each broadcast.

If the format works out well, he may extend the show longer than the allotted thirty minutes. “If people listen, I’ll definitely extend the time,” he says.

Rapp is a high school chemistry teacher and sponsors the ham radio club at his school. He was first licensed in 1976 at the age of five. He is the recipient of the 2014 Indiana Radio Club Council Amateur of the Year award, the 2003 Indiana Radio Club Council Technical Excellence Award, and the 2004 ARRL Professional Educator of the Year award.

‘QRP School’ shows how to have big fun with a small signal

qrp-school-n4ccbEvery amateur radio operator is attracted to different aspects of our diverse hobby. For Cliff Batson, N4CCB, of Nashville, Tennessee, it’s QRP — making radio contacts with 5-watts or less.

“I’m not an expert, but I have quite a bit of passion and enthusiasm for QRP. There’s just something magical about being able to make contacts using less power than a nightlight,” says Batson.

Batson started a video blog called QRP School late last summer and recently added his twentieth episode. He’s already covered topics like using a deploy-anywhere vertical HF antenna (below), solar power operations, building a computer-to-CW interface, bringing your gear along on vacation, and many more. He says that he hopes to add even more QRP-related videos soon.

“Ham radio is a big hobby, and there’s room for all of us to enjoy whatever we enjoy, while letting others do their own thing,” he says.

If you enjoy QRP or want to learn more, you can visit his site at QRPSchool.com and subscribe to his YouTube channel.

HamRadioNow: 60 Meters… Let’s Go Dutch

I’ll coin a phrase for a program like this: Wonkie-Talkie.

The WRC (World Radio Conference) last November ended up with a worldwide Amateur Radio 60 Meter allocation of 15 kHz. You’ll be forgiven if you thought there already was a 60 meter allocation, as many countries have authorized 60 Meter Amateur operation. But it’s never been a formal ITU deal.

But 15 kHz, with a power restriction of about 10 watts into a dipole? (Or 15 watts EIRP – an ‘isotropic radiator’ – a dipole has 2 dB gain over an isotropic radiator?) Compared to the 5 discrete SSB/CW/digital channels we have now with a 100 watt/dipole power limit…. is that a win, lose or draw?

In this Episode of HamRadioNow, ARRL Chief Technology Officer Brennan Price N4QX explains how the WRC ended up with this meager offering, and how hams in the US and other countries with maybe more spectrum and certainly more power may continue to enjoy those privileges. Or not… At the very least, the FCC won’t act on the WRC changes for some time… maybe years.

Well, it’s years if we’re gaining something, like the 137 kHz spectrum that was authorized in WRC 07, that we’re just getting rules opening it up to US hams now. But if we’re losing something?

Brennan is happier to talk about some of the defensive successes at WRC 15. If half the battle is gaining spectrum, the other half is avoiding losing it. And there were many eyes on some of our microwave allocations, but the attacks were fended off.

So, Wonkie-Talkie? You’ll also be forgiven if you drift off to work some DX on 20…. while we still have 20….

Oh, and ‘Let’s Go Dutch’? The contingent from the Netherlands strongly supported a wider allocation and 100 watt limit. They compromised down to 100 kHz, but were out-shouted (apparently there is no voting) by the “almost nothing” faction. So their government immediately authorized Dutch hams that 100 kHz/100 watts anyway.

Brennan says it’s not going to happen here in the US.
