PowerPoles can really suck – why not CliffCon Power Connectors instead?

Who has not had a Powerpole disconnect inadvertently?

If you notice high end gear eschews Powerpoles for high performance positive-interface connectors.

The military ones are pretty pricey and hard to source.

Following the leadership of high end radios like the Hilberling PT-8000A, I’ve instead brought in a supply of Cliff CliffCon Power Connectors, and will be slowly implementing them in my shack.

Here is what they look like:

Okay in comparison they are a bit spendy compared to Powerpoles, but they are positive-interface and will not pull out shutting your station down.  They are also vibration resistant making the selection for field use even more appropriate.  They have redundancy (four wire) which in the interest of standardization within my equipment I will keep to a set pattern.

Yet they allow disconnection quickly.

More on this over the next few months as they are put to use.

Adding 4o3a Genius Gear to the Shack

Adding some very cool station automation gear to the shack – all from 4o3a in Montenegro.

4O3A MADE IN MONTENEGROThe 4o3a Station Genius is basically an ethernet addressable highly configurable shack multi-switch. Ranks 4o3a jokes that it WILL even do your coffee, and technically that is an affirmative!

For the moment the Station Genius is home shack only.

The each QTH has gotten a 4o3a Antenna Genius 8×2 ethernet addressable Antenna Switch. These switches are especially sweet when using a dual-SCU Flex-6700 in SO2R configuration.

4o3a has his Rotor Genius out, which will be next implementation. A not so secret bit of news is 4o3a is tightly collaborating with FlexRadio Systems and a RF Amp is somewhere in the works.

You can read a lot about Ranko 4o3a at his website http://www.4o3a.com

Force12 has been awesome in sourcing this great gear for the USA based ham. See http://www.force12inc.com/categories/4o3a-devices.html?sort=pricedesc for their listing of 4o3a devices.

Did I mention the end goal is all this gear works with SmartSDR and hopefully with a Maestro soon afterwards?

Much more to follow!

Upgraded Amp Installed – Alpha-9500

Finally, i mean FINALLY, got around to putting the Alpha-9500 Amp I bought during one of their specials summer of 2014 online.

The amp and transformer boxes had sat unopened for 15 months.  Seems every time I thought to put the Amp online I was more interested in just getting on the air.

I’ve wanted to pull the Expert 1KW amp out to move it to my Northern QTH on Washington Island, and the “blah” band conditions tonight seemed to offer a perfect opportunity to get the Alpha unboxed and in operation.

Putting the amp together was easy, and the quality of the build shows well.  Both in case any troubleshooting and because of the Amp’s size, for now it is on my main operating bench.

I’m spoken with a friend who builds furniture about doing a shelf unit once I decide what goes where.

Adjusting DDUTIL to control the Alpha was easy and it works slick.  Biggest deal I had was I had asked for the wrong 240v plug type, and had to change it out.

Everything ran well from the get-go, and I banged out a couple QSOs with great reports.  Really like the way it tracks bands and does nudge-tuning to adjust as one QSYs.

One thing I did lose in the change, is the Expert being solid state is an “instant on” amp, where the Alpha has a countdown as it warms up the tube.

And the best part of all is despite the reticence to miss out on-the-air time that led to the Alpha being left in the box while I kept operating, the downtime was trivial.  Should have done it months ago!

Adding a BIG Microphone – Shure SM5-B in the Shack

One the issues I face as an a phone operator is I have a naturally deep bass voice that doesn’t play all that well on the radio for DX or Contesting.  So I’ve been working to help that Broadcaster’s/Ragchewer’s voice into something that works better in the pile-up.

Through Bob K5JIL I was able to obtain the “Unobtanium” – an exceptional Shure SM5-B microphone.  These out of production microphones are prized by professionals and are often priced out of the ham radio operator’s budget, if they come up second hand at all.

Following Bob K5JIL’s very helpful instructions I picked a NOS Behringer Mixer/Amp to interface the Shure SM5-B to my Flex-6700.  My son Winston KC9FVR was super helpful digging out patch cables to get this all working.

The results have been exceptional!   During the mid-November ARRL SSB Sweepstakes I had numerous stations break from the pattern of exchanging reports to comment on the excellent audio.  A session working George W9EVT in fairly lousy band conditions helped tweak a DX configuration that seems to be doing the trick!

I know that it isn’t in every ham’s budget to do a microphone & mixer like this, and I am truly grateful to have the privilege of good gear to help in my efforts in the amateur radio hobby.

Winston KC9FVR also helped figure out the cables needed to put the Wohler AMP1A-LP speaker on line, which is really nice.  I typically wear a boomset, but with the quality speaker as an option it is a lot more “sociable” in the shack when anyone else is in the shack (a small room originally intended as a wine cellar.)

I have figured out the expensive part of the better microphone and speaker though, I already want to duplicate the setup at the Northern QTH on Washington Island!

Hope to hear you on the air!

Adding a 4o3a SSC XL Station Genius to the K9ZW Shack

Working with an evolving slightly complex station, AND wanting to using the LAN-Remote features of SmartSDR V1.4 with the Flex-6700 requires some planning – plus some electronics help!

Not point in reinventing the wheel when really sharp mins have created just the missing pieces to integrate my station.

Enter the 4o3a SSC XL Station Genius

4o3a SSC XL Station Genius - overview

4o3a SSC XL Station Genius – overview

The SSC XL allows control of Antennas, band-pass filters, 4-square antenna systems, beam stacks, beverages, Six Packs, rotators, RS-232 devices and more, per the website information.

Force12 expands further saying it is easier to say what you cannot control.

The main unit seems to have enough connectors to hook up to about anything:

403a SSC XL - Rear Panel

403a SSC XL – Rear Panel

An outboard Relay Board called the SCC-OM controls the various devices:

403a SSC XL - Remote Module

403a SSC XL – Remote Module

Mine just arrived and I am digesting the the manual as I get ready to implement.  As a plus the device is said to be FlexRadio System Maestro ready!

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.
