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.
Summer 2014 K9ZW Shack Upgrades 11 - July - 2014Posted by k9zw in Amateur Radio, K9ZW, K9ZW Shack, K9ZW Uses.

Have a bunch of things in the works – swapping rotors for an AlphaSpid unit and a major home shack computer upgrade (details in a later post). Bought a copy of the latest Ham Radio Deluxe to try out.
For the remote station intended for Washington Island use, a SteppIR CrankIR antenna with 80m kit will be put in use, and have acquired a Flex Radio Systems Flex-6300. Initially I’ll push the old shack computer into service there, but have another box that I’d like to put into use there.
Slow evolution, but very positive improvements!

Search for a rack found either very rough gear, very dated gear (one which I will hopefully acquire for vintage gear later) or hugely expensive racks.
Bought an unused surplus odd comm’s rack – double-ended doghouse thing. Wrong shape, but built like a tank.
Got my buddy Ray to cut in basically in half, moved wheels to the lower section, and reassemble with stiffeners. Ray did this with a purposeful 2 inch set back on upper cube to make it more pleasing.
It is reinforced and now ready for gear
Lower will get shelves for amps, power supplies, and tuner.
Upper will get the Flex-6700, a rackable customer i7 Win7 computer, full W2IHY set up, Greenheron Rotor Control and Array solutions PowerMaster SWR/Watts meter, Rb Frequency Reference, and Flex-5000 (possibly on top of the whole rack if I run out of room).
Looking at another rack I found for vintage/boatanchor gear (SP-600 and similar).
BTW the Collins S-Line Station will go on a desk – show-n-tell sort of thing.
Here is a sketch (click on it for a larger version):
Should work pretty good!
Installing SlippNott Upgrades at K9ZW 9 - June - 2013Posted by k9zw in Amateur Radio, K9ZW, K9ZW Recommends, K9ZW Shack.

The Tennadyne T-8 used two stainless u-bolts for attachment. In the highest of winds the large double booms of the Log Periodic antenna caught enough wind to slightly rotate on the mast.
To counteract this I decided to upgrade the T-8-to-Mast and Mast-to-Rotor connections with Tennadyne’s improved attachment method, the Tennadyne SlippNott. (The much smaller T-28 Log Periodic doesn’t have enough surface area to need this upgrade. U-bolts work perfectly fine for the smaller antenna.)
Another view of the original attachment. It had taken six years to pivot perhaps 10 degrees, though no matter how you look at it, it was moving even if very slowly.
The SlippNott retrofit upgrade uses two machined clamps with roughly one hundred time the surface contact area of the two u-bolts.
Another look at the retrofit in place.
I did the install from scaffold after lowering nd tipping over the whole tower.
Also installed was a second SlippNott providing additional grip of the mast at the antenna rotator rotor unit.
This one was a fiddle to install given the restriction of the three nested tower sections.
Again it provides a huge increase in clamping action and limits the risk of the newly enhanced situation at the antenna twisting the whole mast in the rotor clamp.
A worthwhile project – wish the SlippNott was available when I put the tower and antennas up.

K9ZW 2013 Tower Repair Service List 25 - May - 2013Posted by k9zw in Amateur Radio, K9ZW, K9ZW Shack.

When a complex project is undertaken, I find it a huge benefit to do a sort of checklist.
This way I get my thoughts down on paper and can mark off tasks as they are accomplished.
Linked as a pdf is my Summer 2013 Tower & Antenna Repair-Service List: K9ZW 2013 Tower Repair Service List
Once complete this part of my station should be in good shape for a few years.

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!
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.
