Got Advice for a New Ham?

In the discussion section of the LinkedIn ARRL Ham Radio Operators Group, a new ham asked, “It’s been about 3 weeks since I got my license and I’m nervous of making a gaffe on air. So tell me, what horrible mistakes should I avoid?”

Of course, everyone and his brother jumped in with advice. Here are some of the best ones:

  • Don’t be afraid to make mistakes. We were all beginners once, and we learn by trial and error.
  • Hams are a forgiving bunch, especially when you’re first getting started! (Unfortunately, not all the time….Dan)
  • Listen to what others are doing. Copy what’s good and avoid what doesn’t sound good to you. Ask questions.
  • Check out the local ham radio clubs in your area. You can find them on the ARRL website. Find one that is fun and active with young people like yourself. (Are there any that have active young people? :) …Dan )
  • Best practice is to get on the air and talk to folks. Personally, I’ve found the HT crowd to be a bit cliquish so don’t be surprised if you run into that. It isn’t that they are unfriendly, just shy.
  • It would be a MISTAKE if you didn’t work a FM satellite or two with your new license! (grin) Complete, up-to-date info at … – you do NOT need 100W nor multiple Yagi antennas.
  • Here’s a tongue in cheek article on what not to do on the radio. It’s since been quoted and reprinted all over the internet. You might want to read it to see what to avoid.

Anyone else have some advice for our new ham?

Robots Allowed on 440 MHz Band

Recon Scout

ReconRobotics Inc.'s Recon Scout

Government Technology, a trade magazine covering state and local government issues, reports that the FCC will allow a robot used to transmit live video during rescue operations to transmit in the 430 – 448 MHz band, ending a legal battle between amateur radio operators and law enforcement over the device. The report says:

Called the Recon Scout Throwbot, the robot transmits over the 430-448 MHz portion of the 420-450 MHz frequency band, which is primarily used by the federal radiolocation service. The spectrum is also utilized by amateur radio enthusiasts. The latter group, spearheaded by the American Radio Relay League (ARRL), opposed a waiver request filed with the FCC by Recon Scout maker ReconRobotics Inc. to use the band.

The ARRL argued that ReconRobotics’ claims that the device would be useful in public safety and anti-terrorism operations didn’t prove that a waiver to use the frequency bands was in the public interest. The FCC admitted, in its order approving the waiver, that while some interference in the frequency bands may occur, it isn’t a reason to prohibit the use of the Recon Scout.

The ARRL spin on this is that this is a partial victory for amateur radio. They correctly note that the FCC granted their request for changes in the labeling and instruction manual requirements to ensure that users of the device are aware of its limitations, with regard to interference:

Recon Scout transmitters delivered after April 15, 2011 must carry the following label: “This device may not interfere with Federal or non-federal stations operating in the 420-450 MHz band and must accept any interference received.” The instruction manual must also include the following: “Although this transmitter has been approved by the Federal Communications Commission, it must accept any interference received from Federal or non-federal stations, including interference that may cause undesired operation.”

Identify Digital Voice Modes Using Analog FM Receivers

In the SF Bay Area there has been a recent flurry of activity about digital transmitters on various VHF frequencies which has led some to falsely presume that the signals were D*Star. As it turns out, the signals were from an amateur MotoTRBO repeater. Due to the inability of the local hams to identify the signal type, the trustee of the D*Star system was falsely accused of generating QRM on frequencies 25 kHz away from his repeater.

Identifying digital voice modes without digital equipment, by listening with 5 kHz analog FM receivers, isn’t easy but there are some things you can listen for. D*Star has a fairly unique sound in that every transmission begins with a short 2400 Hz tone burst; if you hear a very short “beep” at the beginning you’re hearing D*Star. MotoTRBO (which is the Motorola branded variant of ETSI DMR Tier 2) is a TDMA mode and as such it has a “sputtering” or “machine gun” sound on 5 kHz analog FM gear. Then there’s P25 Phase 1, P25 Phase 2, NDXN, etc etc. (Note: I don’t know of any amateur NXDN or P25 Phase 2 systems on the air – yet.)

To help clarify some of the current confusion, I’ve dedicated some time this weekend to generating audio recordings of various digital audio modes as received by a 5 kHz analog FM receiver. I’ve also generated spectrum plots for these modes.

High Frequency Electronics: January 2011

High Frequency Electronics - January 2011There are two articles in the January 2011 issue of High Frequency Electronics that amateur radio operators might find interesting:

  1. The Mathematics of Mixers: Basic Principles. This tutorial walks you through the basics of mixers. Because this article is aimed at engineers, there is math involved, but it’s not overly complicated, and if you stick with it, you’ll gain a better understanding of how the mixer, one of the most basic circuits in amateur radio, works.
  2. Design of Input Matching Networks for Class-E RF Power Amplifiers. The author of this article says, “Little attention is brought to the design of the input matching network and to the device bias conditions, with their effects on the overall circuit performance. This paper attempts to discuss these topics through a systematic design and simulation approach for a typical 5 watt class-E power amplifier operating at 150 MHz.”

Note that the magazine is only available as a single PDF file. To read these articles, you’ll have to download the PDF file first.

NASA TV Features NA1SS Aboard the Space Station

A video released on November 23, 2011 features ISS Expedition 25 commander Col. Doug Wheelock, KF5BOC, oeprating NA1SS aboard the space station. This is a really great video. Not only do you get a view of the ham radio station in action, you also get a mini-tour of the space station.

One the things I found amusing about the first part of the video is that you can see Wheelock floating around while he’s explaining how he works the pileups. When he actually does start operating, you can hear how many calls they get up there. They really have be good operators to pull the stations out of all the QRM.

FCC’s Spectrum Dashboard

Many hams feel that they “own” the ham bands. Nothing could be further from the truth, though. In the UHF and microwave regions, we share those bands with other services.

Don’t believe me? Try out the FCC Spectrum Dashboard. According to this website,

The Spectrum Dashboard allows new ways for citizens to search spectrum in the United States. Use the dashboard to find out how spectrum is being used, who owns spectrum licenses around the country, and what spectrum is available in your county.

It covers the frequency range 225 MHz – 3.7 GHz, which are the frequencies generally deemed the best for wireless broadband service, and therefore, the frequencies most sought after right now.

You can do all kinds of searches, including:

  • search by frequency band,
  • search by service,
  • search by location, and
  • browse through the spectrum.

I just did a search for frequencies used by the amateur radio service and discovered that we share the 420 – 450 MHz band with the following services:

  • Industrial/Business Radio Service
  • Public Safety Radio Service
  • Radiolocation Service

This is a great tool for any ham interested in spectrum issues.

Are Wouxoun Radios Illegal?

IC-2ATOn our ham radio club’s mailing list, a new Tech innocently asked what kind of HT he should buy. Since he mentioned that he was going to an upcoming hamfest, he asked about used equipment, and several folks suggested that he look for an ICOM IC-2AT (see right), noting that they were ruggedly built and that many were still in service. They didn’t really not that tuning them involved flipping thumbwheel switches and that to get PL tones you have to purchase a $40 board that you have to mickey-mouse into the radio, but hey, they are built like the proverbial brick outhouse.

Wouxun KG-UVD1Some guys suggested buying one of the new Chinese HTs (see right) now being sold here. They noted that for just a little more than $100, you not only get a dual-band radio, but a boatload of accessories as well.

At this point, Jeff, W8SGZ, our self-proclaimed club curmudgeon wrote:

I’ve been doing a little research.

The US “dealer” is Ed Griffin W4KMA, owner of KMA Antennas in N. Carolina ( So at least there is a US presence. The only thing that  concerns me is one little specification : spurious emission is listed as <30dB.

Part 97 says ” For a transmitter having a mean power of 25 W or less, the mean power of any spurious emission supplied to the antenna transmission line must not exceed 25 uW and must be at least 40 dB below the mean power of the fundamental emission, but need not be reduced below the power of 10 uW.” The question is, is their 30dB enough to get down to 10 uW? With only 5 W to start with, maybe it is.

The particular model in question, KG-UVD1P, is FCC “certificated” (I love that word, it’s so nonsensical) under Part 90, so it should be at least of a certain quality level. And at half the price of anything comparable from the Big 3 (or 4 if you count Alinco), it doesn’t sound bad.

Now, according to my calculations, -30 dB, only gets you down to 5 mW. To get down to 10 uW, spurious emissions would have to be -57 dB. When I replied with that information, Jeff said:

This little radio is causing me a lot more work than I like, but once I get my teeth into an investigation, I can’t seem to let it go.

Although the sales literature (what there is of it) states 30dB for spurious emissions, the User Manual states 60 dB. From what I can make out from the test reports submitted to the FCC, the actual attenuation is in the mid 20s (depending on frequency).

And most bizarre of all is this except from a letter from Wouxon to the FCC:

We would like to have the 136-174 MHz frequency range appear on the face of the FCC Grant of Certification for our Part 90 Certification. This frequency range contains frequencies regarded as usual & customary by the United States Federal Government and its various departments, user organizations and the military.

  1. The applicant plans to ensure that USA users, other than those specifically identified in this letter, not operate within bands which are not allowed by the Part 90, as controlled by the users’ FCC station license.
  2. This devise will not be marketed to USA users, other than those identified in the letter, namely the US Government and its various departments & military, for operation in frequency range out of Part 90.
  3. The applicant acknowledges that it is a violation of FCC rules if the device operates on unauthorized frequencies

Is it just me, or does all this sound like W4KMA is in violation of FCC regulations by selling these to US hams? And are US hams who buy and use them in violation as well?

There has to be a loophole somewhere that I am missing. I mean hams are continually retuning commercial (ie Part 90) equipment to use on amateur frequencies. Why would this be any different? The applicant acknowledges that it is a violation of FCC rules if the device operates on unauthorized frequencies.

So, what do you think? It sounds to me as though the Wouxoun radios don’t meet spec and should not be allowed to be sold in the U.S.

The W8SRC Repeater Guide

“The W8SRC Repeater Guide” is a database of analog FM repeaters across SE Michigan, parts of NW Ohio, and parts of SW Ontario that is constantly updated based on my reception.

On a linked repeater system, “Activity” refers to the activity of that particular repeater being transmitted on.

PLs in parentheses mean the repeater sometimes requires the given PL. If you want to key up a repeater on this database with a PL in parentheses, key up the repeater with carrier access first; if that fails, use the given PL.

At the bottom of the post you will see when this repeater database was last updated and the last addition, deletion, or change of a repeater.  This “change” refers to a frequency, PL, VOIP node, or callsign change as well as if a repeater goes down or back up.

Repeaters in bold indicate any involvement in repeater programming that I have done.

For information on the nets that take place on some of these repeaters, check out the post, “Southeastern Michigan Area VHF Nets.”

Understand the Unlicensed Services

We share several of our UHF bands with unlicensed services, and from time to time, you’ll encounter those signals on the bands. Another reason to be familiar with them is that there are companies that have their eyes on them.

A recent article on this topic, “Understanding regulations when designing a wireless product in the unlicensed frequency bands,” notes:

The wireless unlicensed frequency bands—especially the industrial, scientific, medical (ISM) bands—are the most appropriate for many new applications and products. They are part of the frequency spectrum that can be used without a license. However, products developed in these bands still are required to be compliant with rules defined by the country’s regulatory bodies before being deployed in the field. This article focuses on the technical design requirements and mandates for the US region.

The C. Crane Company has for many years sold radios that they claim have superior AM band performance. They used to advertise a lot on the Coast to Coast AM radio show, touting how the radio was capable of pulling in the show, even if your local station didn’t carry it. They probably still do, for all I know.

There is, of course, a ham radio connection. Art Bell, the longtime host of the show, is W6OBB.

At any rate, C. Crane is now selling the CC-Radio2, which not only touts it’s AM-band performance, but also includes coverage of the 2m ham band. The website says,

The addition of the 2-Meter Ham band may make the CCRadio-2 a life saver during an emergency like hurricane Katrina. 2-Meter Ham operators are early on the scene and they donate their time while handling perhaps 90% of the emergency coordination efforts. The CCRadio-2 can act like a simple radio scanner and search the five memories for ham operator communications. The sensitivity (squelch) can be adjusted for best results.

The C. Crane website has a whole Web page devoted to the 2m band and ham radio in general.

C. Crane sells a whole bunch of stuff that might be of interest to ham radio operators. It’s a site worth checking out.
