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!

W9DXCC Wrap-Up… Hams be prepared just in case, and Buck Rogers Radios

Sitting in our hotel room at the end of the 2015 W9DXCC in Schaumburg, Il.  An excellent experience all around.

The generosity of ones fellows in the hobby cannot be overstated.  I really enjoy these events as the expertise of those with time and resources are shared so willingly!

Keynote speaker was ex-FCC General Counsel, Riley Hollingsworth K4ZDH, who as always spoke well and to the point.  Main take away were two somewhat unexpected things, one about shared humanity and another larger on why the world needs hams even more with the Internet of Things.

On humanity Riley reminded us that those few hams who are awful on the air are largely troubled souls that the system isn’t or can’t help.  Not a few are veterans dealing with those issues.  While not specifically asking for anything from the audience, he brought home that these folk are people too.  Kind of a reminder that we can do better.

The bigger statement was in many ways a vision of a post apocalyptic mission that hams can fill.  As the Internet transitions to the Internet of Things, the risk of systemic failure increases, but worse the risk of system denial (cyber terrorism) has profound consequences that the ham services may help mitigate.

The TEOTWAWKI scenario wasn’t expected, and I have to admit I agree with Riley, including the decentralized ideas he expressed which are the same as those behind the  FREECOM supplement/replacement for EMCOM.

I will return to the FREECOM theme in a future article.

The other huge takeaway for me is again an admiration for the technical excellence and elegance of the FlexRadio Systems Flex-6000 series.

Gerald K5SDR the founder of FlexRadio Systems and Craig K9CT as a member of their advisory team, shared much time showing off upcoming features intended for SmartSDR v1.5, a prototype Maestro unit, and an unreleased hardware accessory.

The intergration and smoothness of the massively expanded capabilities impressed me as much as the feature set.  The feature set had been slowly leaked by FRS so for 80% of the upgrade there is nothing unexpected.

What amazed was how the improvements flowed as if they were always there all along.

I also loved my quick touch and feel chance to play with the Maestro.  Somehow I can imagine a ham not wanting one.  The touchscreen really appealed.

Another fine event- congratulations to NIDXA for putting on such a fine ham gathering.

Dividing Up Gear between QTH’s – Second Look

Did the first update on my radio matrix splitting gear between home and the Island:

HF (Modern)
QTH          Main Rig       Knob Modern Rig   Amp (for Moderns)
Home        Flex-6700       TenTec Jupiter              Alpha 9500/QSO King 6m
Island        Flex-6300      TenTec Paragon II        Expert 1KW
HF (Vintage)
QTH          Vintage Rig           Amp for Vintage
Home        Collins KWM-2A            Collins 30L1
Island        Collins Full S-Line(1)    Collins 30L1
HF Antennas
QTH         Antenna 1           Antenna 2               RX HF          Vertical
Home      T-8 LPDA           W9INN 1/2 Sloper     Pixel Loop     TBD – 1
Island     Hexbeam   $$     W9INN 1/2 Sloper     n/a                 GAP Titan DX
VHF/UHF
QTH            Transceiver   Directional Antenna    Omni Antenna
Home          Yaesu 1800         T-28 LPDA              TBD – 1
Island          Yaesu 1900    #  TBD – 2                     N6JSX Copper J-Pole
TBD-1 – looking at a “flag pole vertical” which may cover both needs
TBD-2 – Initially not a priority
# – may have an Uliboard Interface added
$$ – island will have a W9INN Spacesaver 160-10m dipole as well.
(1) Full Collins S-Line setup consists of:  32S1 Transmitter, 75S1 Receiver, 312B-4 Station Monitor, 516F-1 Power Supply, 30L-1 RF Amp, N3ZI Digital VFO with Memories, Autek QF-1A Audio Filter, SM-2 Clone Mic, Collins Speaker
The Hexbeam is a SP7IDX Mark II HD that Waldi is building for me.
The Island feedline is on the way – between the shack and the tower I have enough 1/2inch Andrews Superflex hardline coming to do two separate runs.  Feedine will transition to DavisRF’s Buryflex for the vertical run (as the tower is a crank down, the hardline is not the right material for the whole feed), a combination which should bring the feedline losses quite low – adding in the vertical run up the tower and the jumper into the shack proper I calculate total system loss less than 1.5 dB loss for the entire feedline at HF and a loss just over 3 dB at VHF/UHF.    These losses are about half of what I have at the home QTH due to the very long feedline runs there.

Note the Island would also gain a Pixel Loop RX Antenna but only if I added a rig that would use it to do diversity reception.  The Flex-6300 cannot do this.

Dividing Up Gear between QTH’s

I’me starting to get a clearer idea of how to handle having to QTH’s

Presently I’m kind of leaning this way on my radio matrix

HF (Modern)
QTH          Main Rig       Knob Modern Rig   Amp (for Moderns)
Home        Flex-6700       TenTec Jupiter              Alpha 9500
Island        Flex-6300      TenTec Paragon II        Expert 1KW
HF (Vintage)
QTH          Vintage Rig           Amp for Vintage
Home        Collins KWM-2A       Alpha-78
Island        Collins Full S-Line    Collins 30L1
HF Antennas
QTH         Antenna 1           Antenna 2               RX HF          Vertical
Home      T-8 LPDA           W9INN 1/2 Sloper     Pixel Loop     TBD – 1
Island     Hexbeam            W9INN 1/2 Sloper     n/a                 GAP Titan DX
VHF/UHF
QTH            Transceiver   Directional Antenna    Omni Antenna
Home          Yaseu 1800         T-28 LPDA              TBD – 1
Island          Yaseu 1000        TBD – 2                     N6JSX Copper J-Pole
TBD-1 – looking at a “flag pole vertical” which may cover both needs
TBD-2 – Initially not a priority

Note the Island would also gain a Pixel Loop RX Antenna but only if I added a rig that would use it to do diversity reception.  The Flex-6300 cannot do this.

Of course there are a lot more things to set up for each QTH

A lot of choices are based on what I have on hand, and I haven’t listed my back-up gear for each QTH, or each go-kit’s gear.

Each QTH gets a Windows-7 PC and an iMac, and most likely a Linux GP Box that will double down as a Music Media Server (I feed my Sonos speakers at home with a headless Linux device already

I may have to build a dedicated box to control the tower at the Island remotely when off the Island, which then can pick up some other monitor-and-measure tasks

Hmmm….

K9ZW Northern Station – The Tower and the Antennas

K9ZW Northern Station – The Tower and the Antennas

The Tri-EX/Tashjian TM-370HD Skyneedle is here at a friend’s trailer yard, where we will do some light refurbishment (scrape and paint some light tin parts that are showing surface rust) and fit the Alfa-SPID RAK Rotor, while we wait for the new base and a few added accessories to arrive.

Here are a few pictures of the tower being removed from storage and transported to my friend’s trucking yard:

TM370HD_Out_of_Storage_02

TM370HD_Out_of_Storage_03

A bit about the TM-370HD – this is a motorized 70 foot tubular tower that has some pretty impressive numbers.

I have a full set of engineering calculations and the wind loading they cite is roughly five times what my array will be, and perhaps 35 times the weight load is available.

Not certain if the numbers they provided are after application of the designer’s safety factor (would presume so, as they were done for code compliance rather than product engineering) so the ultimate wind loading and weight bearing is truly impressive.

Initially going up is a SP7IDX Hexbeam HD Mark II antenna currently in production, and a W9INN Half-Sloper which I had on the ready.

The Hexbeam will cover 6m to 20m and the Half-Sloper will carry onwards 20m to 160m.

I thought I had another Tennadyne T-8 antenna locally sourced, but the present owner decided he didn’t want to sell it even though he’d just advertised it. I’d been interested in having both the LPDA and Hexbeam up to do some A/B comparisons.

Karl and Norman at Tashjian Towers Corporation have been super as usual.

They have in production a new base for me, and I am adding the work platform (tower already has the ladder) which will allow me to do 98% of service work without a lift.

That the work platform will make an awesome birdwatching and other outdoor pursuit platform hasn’t escaped me either! It is quite likely that it will also open up a way for my getting very high speed internet to this QTH, as aDSL isn’t going to quite cut it for remoting a full Flex-6000 based station.

There are a lot of logistics to go – I have verbals from the professional help to get the base in and the tower up, and I have access to a DitchWitch to bury the conduits needed. ( want to run the power separately from the coax feeds and other control wiring.)

I even have some nice touches to add features, like a set of industrial/maritime intercom units so one will be at the tower and the other in the shack.
