CHA MPAS Lite: Chameleon designs a new QRP compact portable antenna system

Many thanks to, Don (W7SSB), who notes that Chameleon Antenna has just introduced the CHA MPAS Lite: a modular portable antennas system covering from 6M – 160 meters.

I know a number of participants in the Parks On The Air program who use the CHA MPAS antenna system–the MPAS Lite is the “little brother” of that antenna, according to Chameleon.

Although designed with the new Icom IC-705 and other QRP transceivers in mind, the CHA MPAS Lite can handle up to 100 watts in SSB or 50 watts in CW.

They plan to start shipping the antenna in early November 2020 and the price for the system is $340.00. That may sound like a lot of money for an antenna (it is, let’s face it!) but if you speak with pretty much anyone who owns a Chameleon antenna they’ll tell you it’s worth it. The quality is second to none. I’ve been testing their Emcomm III wire antenna recently and it must be one of the most robust portable wire antenna systems I’ve ever evaluated.

Also, all of their products are designed and manufactured in the USA.

We recently added Chameleon Antenna to our list of sponsors here at QRPer.com. I’m very proud to include them because one of my personal missions is to promote mom-and-pop companies that push innovation here in our radio world! It’s humbling that they support us too.

The new Inkits Easy Bitx SSB TCVR kit

Many thanks to Robert Gulley (K4PKM) who shares the following news from Inkits:

This is to inform all our valued subscribers that we have launched the much awaited easy bitx kit and few customers have already bought the kit.

The easy bitx kit works on a single band and can be built
for 20mt 40mt or 80mt bands.

This is an enhanced bitx design from the previous versions.
There is a complete manual available with link below.

Easy Bitx Version 1

Complete details are provided in the construction manual to build the kit in 15 Steps.

There are 15 individual kits packets provided to assemble the kit step by step.

The si5351 BFO VFO is provided with the kit in working condition. Only The IF frequency has to be set as described in the manual.

The easy bitx kit is an excellent educational kit for new Hams
who are wish to learn how to build a single band transceiver.
And later use it on the air.

The bitx in various kits and individual mods has been build by thousands of hams world wide, so this way easy bitx is a perfect kit for newbies.

The complete kit can be purchased from our website.

Presently we are shipping world wide with DHL Express.

One week and eight parks with the lab599 Discovery TX-500

Over at our other radio blog, the SWLing Post, I’ve been publishing reports and videos of the lab599 Discovery TX-500 general coverage QRP transceiver. If you haven’t been following those posts, you might like to check out the following articles in particular:

Thank you for the tip, Pete!

Lockdown Lunacy is sending me down the path of QRP EME

Note that the following post first appeared on our sister blog, the SWLing Post.

When my buddy, Pete dives into a project that would have otherwise been placed on the backburner, had it not been for sheltering at home during the Covd-19 pandemic, he calls it an episode of “Lockdown Lunacy.”

Lockdown Lunancy

I don’t think there could be a better name for the bug that has bitten me.

Since my earliest days of reading ham radio magazines–well before I was licensed–I found the concept of EME (Earth-Moon-Earth) communications absolutely fascinating. I mean, communicating with someone across vast distances by bouncing signals off the freaking moon?!?

What’s not to love?

After becoming a ham, the reality set in about how much equipment and financial resources it would take to set up an EME station in 1997. I would need big X/Y/Z steerable antennas, big amplifiers, and very pricey transceivers. Even if I built half the system, I couldn’t imagine piecing it together for less than $3,000 US.

Plus, HF/shortwave signal work was what really pushed me into the world of ham radio.  Once I set up my first dipole and started making DX contacts with my Icom IC-735, I never really looked back…that is, until, I met Bill.

In 2016, my family spent yet another summer on the east coast of Prince Edward Island, Canada, in an off-grid cottage.

The cottage living area.

I brought along my Elecraft KX3, of course, with a LiFePo external battery and PV panel for charging One day, I hopped on the 17 meter band to work a little DX with a large dipole I’d set up in the trees behind the house. After turning on the rig, I heard a PEI amateur radio operator working another strong station in Europe. As he sent his 73s to the other station, I quickly interrupted and asked where he was located. Turns out, he was only 5 km way as the crow flies! After a quick chat, he invited me over for coffee the next morning and to talk radio.

That next morning I discovered two things about Bill (VY2WM / VY2EME):

Firstly, he’s a coffee snob…just like me. Best coffee I’d ever had on the island.

Secondly, the man had been bitten by the EME bug. Indeed, the mission to build a station to do moon bounce communications is really what energized him to play radio.  We spoke at length about EME and it was then I realized that QRP EME was an actual “thing.”

Bill informed me that, with the advent of weak-signal digital modes like JT-65, QRP EME contacts were possible for almost anyone and the investment in equipment, much more modest than in the past. I was truly impressed with how, over the course of a few years, Bill slowly and methodically built his station and started making contacts. Bill gave a lot of credit to his EME Elmer, Serge (VE1KG)–just check out Serge’s big gun station on his QSL card below:

Though Bill didn’t know it at the time, our little talk re-ignited my interest in EME.

Bill and I have kept in touch over the years and only last week, after talking EME a bit more via email, I realized it was time I start my own little QRP EME station.

One thing that pushed me to commit to EME is the fact that both of my daughters are studying for their Technician licenses at present. Both are into all things astronomy and space, so I thought it might be rather fun to give them a chance to play radio off the moon with their Tech licenses!

Like Bill, I plan to take time assembling my QRP EME station. I would like to have all of the components together by December and perhaps start building things like a long yagi and some sort of antenna support by next spring.

I’m facing a big learning curve here. Other than what I learned on my ham radio license prep, I know little to nothing about signals north of 30 MHz!

But that’s the thing about radio in general: I love learning new skills and exploring the world just a little outside my comfort zone!

I’m already putting out feelers for a good transceiver (thinking a used Yaesu FT-897 or FT-100D).

How committed am I? A QRP EME station has been officially added to my Social DX bucket list. That’s pretty darn serious!

Post readers: Any EME enthusiasts in our community?  If so, please comment with any suggestions you may have as I dive deeper into the world of moon bounce!

K-5589: Attempting rare POTA activation Tuesday

If you’re involved with the Parks On The Air program, you may be interested in a park I plan to activate on Tuesday, February 25, 2020.

I plan to activate K-5589, Seneca State Forest in West Virginia.

I thought I’d give a heads-up here in case you need this park–it’s only been activated once before and only a handful of contacts logged.

I plan to start around 22:00 UTC (Feb 25). Time is approximate as this activation will take place after a long day of driving. This activation is in the middle of the National Radio Quiet Zone thus I will have no mobile phone reception to self-spot or provide tips to chasers. I do have approval from the NRQZ coordinator to operate, however.

I will pack my Elecraft KX2 and Mission RGO One transceivers. I plan to deploy a long wire antenna with the idea that perhaps I can serve up 80 meters as well. I will also bring the W4OP loop in the unlikely event I’m not allowed to use a tree to support my wire antenna (this would certainly restrict me to 40 and 20 meters).

Look for me on 3,986, 7,286, and 14,286 kHz.

If, for some reason, I can’t activate this site due to access, I will attempt to activate K-1808 (Cass Scenic Railroad State Park) instead. Both are rare.

If time allows, I’ll attempt both!

Dave Benson’s new Phaser Digital Mode Transceiver kit

Just in time for Christmas, Dave Benson is back with a great new line of Monoband Digital Mode Transceivers! 40 & 80 Meters is available now 30 & 20 Meter Rigs to follow shortly.

Time for me to contact Santa Claus and update my Christmas Wish List 🙂

These are Single Signal Phasing Rigs not DSB.

WOW! Thanks for the tip, Pete! I think I might give Santa a hint! This looks like a fun kit!
