An Excellent FlexRadio System Write-Up on the Origins of the 6000 Series Online

There is an excellent FlexRadio System write up on the origins of the Flex-6000 series SDR radios and SmartSDR software online :

The FLEX-6000 was born out of a government project we did that involved direct sampling. At the time in 2010 we all believed (as Elecraft has publicly stated) that it would not be possible to build a direct sampling receiver with as much dynamic range as a superhet or direct conversion radio. When we did the government project, Gerald worked a lot on the numbers and RF architecture and we discussed how to get the best dynamic range out of a direct sampling receiver. We were able to use a very early sample of an Analog Devices ADC in that project and found that we were getting better dynamic range than even Analog was reporting, largely because of how we selected key parameters. Gerald realized that we could build a better direct sampling radio than anything we’d built before.

Once we realized it was possible to build a direct sampling radio, all the “what if…” conversations started. What could we do if we did this? What would someone do with that? Would it be better if we did this or that?

Rocky Ridge Farm on Washington Island, WI – Third Radio Activation

This weekend is my third working the CrankIR and the Flex-6300 from Rocky Ridge Farm on Washington Island.

Getting past the  learning curve.

Was too chilly to comfortably operate outside, so set up the radio inside one the kitchen table.

Easy DX this time and I’ve figured out the band change process pretty well.  Worked on 10m, 12m, 15m, 17m, 20m, and 40m.

Great fun!

Rocky Ridge Farm on Washington Island, WI – First Radio Activation

Even though we have leased the farm for months, I first got around to setting up a portable station this weekend.  Usually when I am on Washington Island I have the luxury of guest operating from George W9EVT’s mega-shack, and even in this attempt George W9EVT saved the day helping me get on the air.

Equipment used was:

• SteppIR CrankIR antenna with radial and 80m kits
• FlexRadio System Flex-6300 transceiver
• A Toshiba Laptop running Win7-Pro I borrowed from work
• Power supply from my spares shelf
• Cisco gigabit router
• cables and power cords/distribution from my spares

This was our first use of the CrankIR and the Flex-6300, so we had a bit of a learning curve.  It was also a fresh install of SmartSDR, SmartCAT, DAX, and fldigi on the Toshiba which all had to be configured.

W9EVT saved the day…

Pictures cannot convey the experience of doing a first time setup of the CrankIR – an easy task once you’ve done it, but a dickens the first time.  Winston KC9FVR helped the first setup and I don’t think I could have done it first time without my son’s participation.

I quickly discovered I had no audio out – I forgot to bring a headset or speakers, and ten Flex-6300 does not have an internal speaker, so my initial efforts were digital mode.

No joy there as my signal apparently wasn’t readable on PSK31 and without audio out the portable stup wasn’t going anywhere.

So the next day, hat in hand, I borrowed a headset from George W9EVT and switched to SSB.

Fairly quickly I was able to work a good number of stations on 20m and 15m phone, including several DX stations.

Found that the software juggling on the laptop was a pain, and ended up doing all the logging on the cardboard tabletop cover I used to have a mouse-ready surface.  Later I entered the QSOs into eQSL and I’ll import the adi log file into my main log later.

Mother Nature ended my activation early as it started to rain and the winds started whipping.  Knocking everything down went smoothly and with Labor Day still windy & rainy, further Rocky Ridge Farm activation will wait for another day.

Of course I have updated my gear checklist to include headphones and speakers for the next activation.

Adjusting Gear and Forward Thoughts at K9ZW

Added a couple bits of kit – picked up a Flex-6300 from a ham who tried it and didn’t really take to a computer driven rig. Worked out for both of us as I avoided the backlog so I could get another Flex-6000 series radio to use up north on weekends, and he can change to a rig he is comfortable with.

It is worth commenting that there are some basic truisms about equipment that include the absolute that “Not every ham has the same style, interests and goals, so by definition no one radio will be the perfect rig for every ham.” “Horses for Courses” as they say.

In working on my Collins Vintage S-Line Station it has become pretty obvious than an antenna coupler/tuner would be an advantage if I wanted to be able to switch-in the S-Line station with my present antenna setup. I found a British Decca/K.W. 107 SuperMatch that will do the job while blending in with the S-Line gear form-factor.

The S-Line Station has been 18 months or more in the assembly, so it is time to get it on the air! This should do it.

Dayton 2014 – a recap of K9ZW’s Hamvention

Dayton Hamvention 2014 was interesting, though less profound that past years.

First products and exhibits:

• An awful lot had nothing new to show.  Nada, boring nothing that I couldn’t read about on the internet.
• Same no reason to be here applied to pricing – almost every vendor has figured out they can increase sales by offering “Dayton Hamvention Pricing” on-line.  Many include free shipping and it is sometimes the case that the sales tax due is less if dropped shipped.
• Still plenty of “vaporware” with prototype products being shown year after year with no real product to sell.  One questions how many years hams will show up at Dayton with cash in their pocket to buy antenna auto-tuners that never go into production (Alpha is not the only vaporware tuner, where is that long promised Kessler AT-AUTO-II updated unit? [EDIT:  as Don Kessler pointed out he was showing a new remote tuner at Dayton 2014 – more on this to follow]) or amps/transceivers/antennas that are “almost there” but have no ship date?
• Dayton remains a place where the one-man-band is on equal footing with the robust corporations and mega-corps.  Unfortunately many interesting product offerings are “one heart attack” away from being unsupported/out-of-business.  Not a terrible thing if one is buying a couple hundred dollar unique product but a real concern if one is considering investing thousands in piece of gear that might be orphaned by the smallest of issues.  Ditto on products by companies where the sole proprietor is elderly and hasn’t worked outa  succession plan.  If you ask there are some surprises where small firms have this wired, bit most don’t.

Let’s talk about Dayton itself:

•  Less Road Construction at Dayton – sees that some of the “forever projects” have finally finished, though downtown is still a mess.
• The Hara still sucks.  Same holes in the pavement, leaks in the roof, and grubby nature.  Being cool this year odor was down.
• More restaurants have been built nearby, which opens up opportunities.
• Staff seemed happier.  People are people, and the ones I dealt with this year were plainly nice folk.
• The affiliated hotels suck.  Tales of no hot water at one hotel, heat stuck on full blast at part of ours, messed up reservations and catering (one banquet I attended the hotel staff for the second year running couldn’t manage to open up the cash bar having forgotten criticals like ice, cups, mixers…. or change..) from hell.
• The interstate getting there was hammered, under construction, overcrowded and not much fun driving.

Then may particular interests/purchases:

• AlphaSpid RAK purchased from Alpha Radios in Alberta will be replacing my Ham-IV.  This looks to be the easiest high-resolution replacement.  Once the unit arrives I will schedule a lower lowering to do the rotator swap.  The Green Heron controller I have should work for the AlphaSpid with a few internal jumper changes inside the controller.
• Green Heron will be doing the station integration for my ArraySolutions RatPAK-N remote antenna switch.  This is a left over Dayton 2013 project that I arranged to pick up a few bits for as I finish it up.
• W2IHY station selector system needs finishing off, again a Dayton 2013 purchased project I didn’t make time to complete.  Got my questions answered at the W2IHY booth, so my excuses have to end…
• qslradio supplied the rig runners and power pole connectors for Rocky Ridge Farm Station.
• Spoke with Mr Hilberling, and while it would be a budget buster right now I do hope to have one of his radios with amp in the next year or so.
• Spoke with Jay at ArraySolutions and I sure am interested in the VNA gear.  Maybe this winter, I will get one to learn about it.
• Spoke with several of the team at Alpha Amplifiers and they have no idea when I could buy a  combination package of an Alpha-4040 Automatic Antenna Tuner and Alpha-9500 Automatic Amplifier.  I decided not to buy an amplifier even with the nice show special being offered.

Banquets I attended:

• Friday Night – the Collins Collectors Association 80th Anniversary Banquet.  Met some really great people but this is the one where the registration was very slow, the bar wasn’t ready nor stocked, and the presentation & drawing prizes were extremely introspective to the hardcore Collins collector.  I actually cut out to take a phone call (son Tom KC9JGD relocated that day to near Rapid City SD) and decided to not return.  This group faces some challenges as its membership ages which I don’t have a solution to suggest.
• Saturday Night – The Flex Radio Systems annual Dayton Hamvention Update Banquet was a pleasant contrast with quick & slick registration, dual stocked cash bars ready to serve and a lot of information about where FRS is going.  Only think I think the FRS folk missed is dishing out to each dinner attendee some special swag – pens/hats/pads/pins.  Fairly lame door prize drawing for a couple hats, two oversized re-discover radio button/signs, a flex control and a Flex-1500. Seemed like nine or ten items was not enough for nearly 190 attendees.  Not enough to build a buzz in the crowd.  Otherwise a nice banquet.

Family Matters:

• Riding with me to Dayton were my friend George W9EVT from Washington Island and my cousin Bill KC9YBL.  Made for a truck full of Extra Class Hams.
• Living in the area we met with cousin  Kuby N6JSX (Dale to me) and his wife Becky N9KUV.
• We meet with more family in Ohio, Chicago and Wisconsin.  Good time had by all!

Again I wonder about Hamvention 2015 – should I attend or is next year the one to try Hamcation or Hamcon instead?

It wasn’t for the ease of seeing family and the control of driving, the answer could be pretty easy to go to one of the other shows.

I’ll have to do some pondering and decide….

What we saw new at Dayton 2014!

Following up on my predictions of “What will we see new at Dayton 2014?” here are some notes:

• A merged Alpha Amplifier/Ten-Tec potentially offering positive news on the long overdue Alpha-4040 Antenna Tuner – no date yet on the 4040 as at least one more major revise is in the works for the prototypes.  Closer but no cigar.
• Several new evolutionary radios from Icom, Kenwood and Yaesu with continuing emphasis on attractors like D-Star, Remoting, Emcom, integrated GPS/Bluetooth and Contesting. – yup, lots, with the IC-7800 Upgrade of special interest as it is net plug and play.
• The brand new Flex Radio Systems Flex-6300 transceiver offering much of what the Signature Series is about at a mass market price point, along with the end of April SmartSDR v1.2.1 which added the awaited Waterfall/Panafall with many other features. There may be a remote possibility of a further SmartSDR update at Dayton. – off to the FRS dinner tonight and hope to have news afterwards.
• We should get a first look at the HPA-8000A 1kW Solid State Amplifier rounding out the high performance PT-8000A Transceiver desktop. – they had a single amp in the booth with USA hams likely to get a supply in later 2014 due to FCC approval lead time.
• Several Antenna Manufacturers have announced new models, with several interesting LPDA (Log Periodic) offerings tailored to meet the new Flex Radio Systems Signature Series radio requirements.
• Connectivity Galore with Bluetooth, In-Shack and Remote connectivity options of every type and style. Expecting to see everything from ZigBee Modules you can solder into your project to desktop setups you can use to remotely operate one of the rent-by-hour stations.

I am sure there will be much more, and hopefully a few surprise product launches too! See you there!
