The lab599 Discovery TX-500 QRP transceiver price and anticipated delivery via HRO

This evening, I discovered that HRO now has the long-awaited lab599 TX-500 transceiver available for purchase on their website.

I had actually placed an order for the radio, but I’ve asked to cancel it because I should have a loaner available for review.

Without a doubt, the TX-500 is one of the most anticipated QRP transceivers this year. Field operators have always wished for a rugged, weather-resistant portable radio and the TX-500 looks like it will fit the bill! Based on some of the videos we’ve seen, it should perform as well.

Click here to check out the TX-500 on the HRO website ($789.95 US at time of posting).

Update: HRO informs me that the lead time, or anticipated delivery is still weeks away.

New Icom IC-705 videos and few answers to your questions

I’ve been getting a number of inquiries from readers lately about the new, yet-to-be-released, Icom IC-705 QRP portable transceiver. Here are a few quick answers to frequent reader questions:

  • “Will you review the IC-705?” Yes, I certainly will. If the loaner unit from Icom has a long lead time, I’ll plan to purchase one from the first production run and may sell it after the review. (Only since I already have *way* too many QRP transceivers!)
  • “When will the IC-705 start shipping to customers?” That’s a tough one to answer and, of course, I have no affiliation with the manufacturer so really can’t comment. As we’ve mentioned before, IC-705 production like other products this year has been delayed due to the Covid-19 pandemic and the impact on supply chains. I do know that Icom hopes to start shipping the IC-705 within the next few months. Availability may vary based on where you live since Icom has regional market headquarters.
  • “Does the IC-705 have an internal ATU?” No, it does not. However, Icom recently announced that they will produce an antenna tuner for the IC-705 with the model number AH-705. There are no details available at time of posting, but we must assume this is an external ATU.
  • Will it ship with a battery pack, or do we have to buy it separately?” The IC-705 will include a  BP-272 Battery pack, HM-243 Speaker-microphone and OPC-2421 DC power cable.
  • With a color touch screen display, won’t the IC-705 current drain be too much for operating on a battery?” Since I’m primarily a field operator, this was one of my first questions as well. Turns out, Icom has employ some agressive techniques to make that display as efficient as possible. Check out the promising numbers from their recently-published specifications page:
  • Will the IC-705 double as a portable shortwave radio broadcast receiver?” The short answer is yes, but we have yet to actually put this general coverage transceiver to the test. What we do know is that the AM bandwidth can be widened to 6 kHz according to the specifications sheet. We also know that its receiver range is 0.030–199.999 and 400.000–470.000. The IC-705 will cover the entire AM broadcast (mediumwave) band and the entire HF/shortwave spectrum with no gaps. How sensitive the IC-705 will be outside the ham radio bands remains to be seen.
  • Will the IC-705 include the 4 meter band?” I’ve gotten this question from a number of our UK readers. The answer is no. There were conflicting reports early on, but Icom UK posted this message on May 29, 2020 noting: “We regret to inform you that contrary to our earlier messages, the 70MHz (4 Metre) band will not be included in our much anticipated IC-705 QRP SDR transceiver.

The Halcyon Days of CB Radio

This morning, I read a message from a ham radio operator who was just awarded a vanity call sign in honor of his father’s 1970s era CB radio call sign. He was obviously very proud of the role CB played in his “formative” radio years.

Although I often only think of the impact my first transistor radio and first shortwave radio had on my life, CB radio also played a major role.

My father entered the CB radio scene in its early days here in the US. His FCC-issued call sign was KJD1166–it’s laser-etched in my memory from hearing him call it so many times when I was a kid.

Dad had a number of radios, but his favorite was a yellow Robyn T-240D (above). As a kid, I really admired this radio; not only was it stylish, but it also had a digital channel display, amazing audio, and that “Range Expand” toggle switch!

In the 1970s, the CB radio scene in my hometown was dynamic and rather well-organized. Every evening, my dad would turn on the radio and connect with a vast network of radio friends. Not only did they have call signs–and used them–but they also had the best CB handles (like “Tombstone Pete,” “Lady J,” and “Robby Rocket”).

The local CB radio scene also had in-person social meet-ups–a place where you could put a call sign and handle to a face. And let me tell you: you’d see a wide array of folks from all walks of life there. A proper melting pot.

Dad also took me to the CB radio repair shop where he’d buy supplies and occasionally get something fixed. I loved looking at the workbench full of half-disassembled radios. At one point in my childhood, all I really wanted to do was have a workbench like that and dig into radios. Even at a young age, I knew how to use a screwdriver and could void pretty much any warranty.

After the FCC did away with call signs, much of the local CB community fell apart. My dad would still check-in with friends on the air the years following, but much less frequently.

CB: A Ham Radio Gateway Drug

No doubt about it: CB radio eventually lead me down the path to ham radio.

While I never participated in the 70s CB radio scene like my dad, my best friend and I used CBs to communicate with each other across the neighborhood in the 1980s.

My buddy grew up in a multi-generation household and telephone time was restricted to grown-up use (and his teenage sister).

CB radio bridged that communication gap for us. At one point, we both used Realistic 5 Watt 40 channel walkie-talkies–it was incredibly fun and effective.

CB radio, and my dad, taught me about the components of a radio transmitting system–the radio, coaxial feed line, antenna and grounding, etc.–and also concepts like power output, standing-wave ration (SWR), and skip.

I still own my 40 channel CB walkie-talkie (a Realistic TRC-217) and my dad still has his Robyn T-240D, although neither have been on the air for decades. Still, I feel very nostalgic about the 1970s radio scene and should certainly give it credit for paving the path to my ham radio ticket.

Did CB radio play a role in your life? Please comment!

The book that took David down the path of SWLing and ham radio

Many thanks to SWLing Post contributor, David (G4EDR), who writes:

I enjoyed reading about the vintage shortwave radio book memories from Bob W6ACU and it prompted me dig out the book which got me started in SWLing back in 1970. It was in a series of illustrated teach yourself books and the title was ‘Radio’ written by David Gibson G3JDG [see cover above].

I borrowed it from the school library and renewed the loan so many times the librarian suggested I should buy my own copy so that someone else could have the chance to borrow it! I still have my own copy of the book bought with my saved pocket money for the sum of 15 shillings. That was before the UK changed to decimal currency (15 shillings is 75p in decimal).

The book covered basic radio theory and several construction projects including a crystal set and an atu which I made and I also learned all about amateur radio and QSL cards.

That was the start of my life long obsession with radio. How things have changed over 50 years! Thank you for allowing me to rekindle those happy early days of this fantastic hobby of ours.

73, David – G4EDR.

Thank you, David, for sharing your memories with us. It’s amazing, isn’t it, the impact one book or one radio can have on one’s life!

US global media agency seeks to kick out international journalists (Southgate ARC)

CNN Business reports: Efforts to clean house at the US Agency for Global Media continued this week as leadership indicated that international journalists who work for Voice of America (VOA) will not have their visas extended and a widely respected top editor at Radio Free Asia was fired, explained three sources familiar with the decisions.

Under the new leadership of Michael Pack, who took the job as USAGM’s CEO last month, the organization which oversees US-funded broadcasters VOA and RFA among others has been thrust into a wide-ranging shakeup which appears to be politically motivated.

With indications that Pack is not going to allow visas to be extended for international VOA journalists in the US, there are dozens of journalists who could face retaliation if they are forced to return to their home countries.

In Colorado Springs and beyond, ‘magic’ of ham radio breaks doldrums of COVID-19 (The Gazette)

On the windswept prairie east of Colorado Springs, in a ramshackle trailer plastered with maps and codes associated with every sector of the world, strange sounds are coming from a radio.

Static mixes with R2-D2-like beeps and bops. Don DuBon has a microphone in one hand while the other twirls a dial, searching.

“Alpha, foxtrot, zero, sierra,” he says, speaking into the void. “Alpha, foxtrot, zero, sierra…”

That’s the call sign for the Pikes Peak Radio Amateur Association, the group of enthusiasts who make this trailer their base.

Hams, as they’re also called, take special pride in their contact with each other across the globe. They keep log sheets. One here by DuBon shows contact made with a Chuck (call sign KI6HK) in California; a Jake (K4BOM) in England; a Brooks (K2CNN) in Alabama; and others in Uruguay, Brazil and New York.

DuBon, N6JRL, is looking for others.

“Spain,” he says, recognizing the call sign heard through the clutter. “That’s a station in Spain. … He’s got a bunch of people calling him.”

“It’s called a pile-up,” says Jim Bishop, KD0KQL, fellow club member and retiree. The two are now gray but engaged in something that makes them feel young, still boys with their radios.

The Pikes Peak Radio Amateur Association (PPRAA), counting a little more than 100 members mostly from generations past, is among an underground but bustling faction of American culture. Active call signs given by the Federal Communications Commission represent 0.25% of the U.S. population. In El Paso County, the ranks number about 3,500.[]

FCC Continues to Prosecute Pirate Radio Operators – Two Settlements with Identified Violators (Lexology.com)

Pirate radio operators continue to be a problem – particularly in major metropolitan areas. The week before last, the FCC resolved two long-pending cases against pirate operators through negotiated settlements. In one case, the FCC last year initially proposed a fine of $151,005 for the illegal operation. After examining the operator’s finances, the Bureau agreed to a $4,000 fine now, with a penalty of $75,000 should the operator violate the law again (see this decision against an operator called Radio Concorde). In the second case, the FCC had proposed a $453,015 fine last year, but agreed to take $5,000 now, with penalty of $225,000 if the operator violates the terms of the consent decree (see the decision dealing with operator Radio TeleBoston). Last year, we wrote here about the much larger fines initially proposed for these two operators.

In both cases, the FCC seemingly recognized reality in taking the small upfront payments now rather than trying to collect huge fines that likely were beyond the ability of the operators to pay. The FCC also required the surrender of the operator’s equipment and a commitment to stay away from pirate radio for 20 years or face much larger fines. The big fines initially imposed in these cases were set even before Congress enacted the PIRATE Act early this year. The new law allows for fines on illegal operators of $100,000 per day, up to a maximum total fine of $2,000,000. Even without the full effect of the PIRATE Act, these cases show the deterrent effect of these large fines.[]
