Putting it all on the Air – Pondering Station Design for K9ZW

Radio gear is like rabbits – when you are not looking they somehow seem to breed producing more (and more!).

Doing some sketching trying to work in a multi-station format into too small of a space and budget.

Minimally I would like to be able to switch easily between my present main Transceiver (Flex-5000A), the future Flex-6000 (which with its features is a bit trickier to configure into a multi-station configuration) and a “Guest Transceiver” position which will either be filled with vintage gear (the Swan/Dentron station or the Collins S-line Station) or a modern transceiver.

The plan is to use Julius W2IHY’s 3×1/1×4 Switchgear Combo as my solution.

http://www.w2ihy.com/one-3-x-1-controller-two-1-x-4-switches.html is the configuration I will start with.

Looking over Julius W2IHY’s new switch gear at Dayton it is obviously as rock solid as his audio products.  It is easy to admire the build and technical quality, as well as his W2IHY Dayton team.  Great product, great specifications and great people – quite a combination.

Julius was able to fix me up with 90% of what I wanted at the show, and within days of Dayton had dispatched the 3×1 Switch with Rack Mount Ears and a Cable needed to round out my configuration.

The attention to detail in his gear is impressive.  Much of the gear has two relay banks to select from – a high power relay for QRO use (I think I heard 5KW rated) and a high-speed reed relay for QSK & Digital use.  The end user can select between with internal jumpers.

Even the 1×4 boxes come in more than one pre-configuration depending on whether the desired state when a port is not selected is Grounded or Open.  My design needed one of each.  Again I understand I could have opened a box a reconfigured, but Julius has it covered from the get-go.

Julius was even so kind as to do a marked up custom Configuration Sheet for my shack – see: W2IHY Switch Gear Config for K9ZW  pdf data sheet.  Have a look and let me know what you think!

Amazing service!

On the Audio side I will be using Julius W2IHY’s 8-Band Equalizer/Noise-Gate, EQPlus Compressor/Downward-Expander and IPlus Audio Switch.

It may be a couple weeks until I have all the gear in place, and I’ll have a user’s setup report then.

Dayton 2013 – Friday Report

Been an interesting Hamvention so far.

There are some new products – the IC-7100 successor to the IC-7000 and the TS-990 was being shown.

Interestingly the Kenwood was somehow locked up and the floor team didn’t have a way to reboot it.

My first focus was a visit with Julius at W2IHY where I was having a very serious look at the new line of switch gear.  I’ve always admired the quality of his gear and this new range of products doesn’t disappoint.  http://w2ihy.com will fill you in on the new gear.  I already have a lot of his audio gear and will be adding some of the new line.

A visit at Hilberling found that they fully up and running for the USA market.  Never intended to be “everyman’s transceiver” they have delivered over $1million of these new “uber-radios” so far.

Long chat at FlexRadio Systems and one has to admire their willingness to trickle out radios even while the eagerness and requests to ship are so huge.  It was hard to get up close with the crowd, but i did get some time on their Flex-6700 simulators.  Tim W4TME was kind enough to give me a guided tour of the inside of the visual Flex-6700 – and I obliged by pretending I knew what all that stuff was (actually it is pretty neat and straight forward.)  FlexRadio Systems has put the Flex-5000A on end-of-life status with a when stock is sold, they are all sold noted on their website.  Flex-5000A critical components have become unavailable and it was fairly easy to see their was a product line overlap (a fully loaded Flex-5000A was within five hundred dollars of the new Flex-6500).

Very nicely the FlexRadio Systems team explained to me that when my radio is ready to ship, it will be ready.  Tomorrow is the FlexRadio Systems Dayton Hamvention Dinner where I hope to hear much more.

Over at Alpha the long awaited Alpha-4040 Tuner was being shown in working form.  The tuner looks well worth the wait.  The touchscreen display is awesome!

I was really taken with the dual port VNA (Vector Network Analyzer) at Array Solutions.  This “black box” connects to your PC to create a full test lab doing much more than I can recollect.  Jay (Array Solution’s owner) showed me how to do a TDR (Time Division Reflectometry) examination of a feedline and antenna system (including the VNA even measuring a human hand touching an antenna element), how to do a full in depth coil measurement, and a bunch of stuff I am going to have to brush up on.  This look like my next test gear addition.

The Japanese LUSO tower people took the time to explain their very cool crank-up towers.  Really amazingly serious amateur radio gear.

I was surprised at a couple vendors living the past.  Some of the big name rotor/rotor-controller folk have amazing new technology (Green Heron Engineering is a personal favorite, and they sold me one of their new station control modules) and other are promising to catch up to market norms by adding computer control to their rotor-controllers in perhaps a year….

TenTec was showing off their latest and a new Model 506 “Rebel” QRP transceiver I hadn’t seen before.  Apparently this new radio has the guts of an Arduino running the show – very cool!

More tomorrow!
