Putting it all on the Air – Pondering Station Design for K9ZW 23 - May - 2013

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.

“There is substantial professional interest in the Flex-6700R for other than Amateur Radio usage.” Could you elaborate, what is the professional interest in this Radio? I have ordered my 6700 May 21, 2012.

Hi Dan KD2ALV/HK3DC

I would be speculating what professionals were looking at the receive only Flex-6700R and have no further details other than the comment made to me.

That said, in speculation I would think the quality of the dual-SCU receiver would have a huge range of professional applications. Radio designs with superior receive ability and broad band capability would be useful for everything from broadcast monitoring to emergency equipment.

Again speculating, the Flex-6700R might be useful for those responsible to monitor & maintain NDBs – if you saw Stu K6TU’s article on LF reception he had great performance in this area.

If one were doing a Propagation Study this very fine Receiver would be an advantage.

Evaluating the quality of Commercial Broadcast transmissions might be another avenue.

There are purpose built surveillance radios (FlexRadio Systems even has one of their versions (CDRX-3200) on their website) which would suggest the Flex-6700R is less likely to find a home there.

The hobbyist SWL crowd has a real treat coming to them when they discover the Flex-6700R – imagine the circles, especially if diversity were implimented, that the Flex-6700R would run around most available SWL gear?!

Please remember I’m deducing some possibilities and can’t speak for FlexRadio Systems themselves. I’m going to make an additional guess that the sales contracts for some of their clients might restrict FlexRadio Systems from talking much about the safety, security, research and other professional uses of the kit they make.
