FlexRadio Systems Flex-6600M Transceiver and Power Genius XL Amplifier in early use

FlexRadio Systems extended me an opportunity to acquire one of the first production run Flex-6600M Transceivers and a few weeks back a PowerGenius XL Amplifier both early as a “Beta Team” participant.  (I’ll be abbreviate Flex-6600M as just “6600M”, Flex-6700 as just “6700” and the PowerGenius XL Amplifier as “PGXL.”)

As mentioned, I’d participated in a similar program when the Flex-6700 launched.

The “Beta Team” really couple be considered “Late Addition Alpha Team” or “Temporary Alpha Team” or “Little Alpha Team” team members, as to handle the information flow.

Quick disclaimer FRS is still working on parts of the product package for the new Radios, so while I will receive production hardware, the configuration and software parts are not in the final general release form. This again parallels the Flex-6700 program I had participated in.

In my case this new Flex-6600M it will temporarily displace a Flex-6700 at my main home QTH.   I’m definitely planning to retain that Flex-6700.  I have configured the station temporarily to allow fairly quick A/B switching from the 6600M to the 6700.  I have enough W2IHY switchgear to potentially hardwire the A/B setup, but for now the intent is to do plug and play.

My shack is compact – and is especially compact as the sanctity of my radio shack in the old wine cellar room has been encroached  upon severely by buying too much wine in Italy and from a long time Alpha team’s family’s California Vineyard, all arriving as I decided that personal health triumphs.  So those cases have filled what extra area the shack had.

To make room, after my personal testing of the PGXL I’ve decided to remove the Alpha 9500 Amplifier and the Expert SPE 1KW backup Amplifier physically from the operating area, putting them on my “shack reserve shelving” for the moment where they join my fail-safe Alpha 78 Amplifier and a 6M King Conversion Amplifier.  Actually I enlisted some help from my youngest son, Victor KC9NWB, as any college kid home for winter break should get a chance to lug his Dad’s ham shack gear around, right?

I still need to figure out where to move a few items to, especially the audio-amplifier that was going to help tweak my main Shure SM5B microphone’s voice signal but has ended up set so flat that it is really just isolation and audio signal gain.   That said, here is the 6600M/PGXL as of January 6th 2018:

K9ZW 6600M and PGXL Overview


I’ve found the 6600M/PGXL combination really awesome to use.  Reports “out of the box” have been so good that I’ve not spent much time optimizing settings yet.

My station is pretty simple, smaller scale, and gets ends up effective.  The6600M/PGXL combination have in two simple pieces of gear have noticeably improved my station.

I was having so much fun working DX on 20m, that I forgot to snap a photo to share until propagation changed enough that 80m was the lively band.  My present home antenna situation is limiting on 40/80/160m bands compared to 20/17/15/12/10 and the UHF/VHF bands.  So I turned things back on a shot a quick snap will running 80m figuring you all have seen a full panadapter screen before!

So here a quick “station selfie” snap:

As previously mention that like both of my Flex-6700’s, this new Flex-6600M was ordered with the GPSDO option.  If software eventually allows I hope to use the accurate time stamping on a station-mixing basis.  If that doesn’t happen the extra accuracy never hurts.


My “Late Addition Alpha Team” status came with my agreeing to not speculate and to not detail the exact Alpha Team’s progress & problem solving details, but I am pretty sure it didn’t have any agreement preventing my speaking to how absolutely engaged the FlexRadio Systems, 4o3a Team, and the Alpha Testers really are.  The efforts, feedback/update speed is truly impressive!!

More later this week, and as a teaser I’m going to add two more photos that I will explain in-depth in a later posting – with the SmartSDR versions improving I’ve run into a band situation where 160m was unworkable until I engaged the FlexRadio Systems exclusive WNB (Wide Noise Blocker).


SmartSDR no filters and a bad 160m band

Pay attention to the waterfall difference – the noise is gone I was in business, if RX a bit faint (55 to 53 – clear but weak).  As for the source of the noise, I’ll have to see if it reappears and track it down.

Much much more to follow!

There have also been massive deliveries of the needed connectors and other parts – whew!  I am sure glad I’ve not seen the costs all tallied in one spot – ouch!

All in all the order and assemble is fun other than the bills.  Now in spring the read work begins!

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!

A Northern Station for K9ZW

Having secured a long term QTH on Washington Island, Wisconsin (US Island WI-001L), I’ve started putting together a station.

Here is what is planned:

• Transceiver – Main – FlexRadio Systems Flex-6300 w/ATU
• Transceiver – Back-Up Unit – TenTec Paragon II
• Transceiver – Vintage Net – Collins KWM-2A
• Amplifier – Expert 1Kw Solid State
• Tuner – Palstar AT-Auto fully upgraded by Kessler Engineering
• Radio Computer – Custom Built Win7 “blade” (or possibly a Neal Campbell PC)
• Audio Gear – full set W2IHY gear
• Frequency Reference – Homebrew Rb-Source
• Tower – Tasjian TM370HD SkyNeedle
• Main Antenna – 20m through 6m – SP7IDX Hexbeam II HD
• Main Antenna – 160m through 20m – W9INN Half-Sloper
• Vertical Antenna – 80m through 10m – Gap Titan DX
• Rotor & Control – Alfa-SPID RAK with Prog1 Controller
• Antenna Switch – 4O3A Signature/Sky Sat 1A2R Switcher with PTT Router (TBD – under review)

I’ll use my usual BuryFlex Coax as supplied by DavisRF with N-Connectors as usual where possible.

The only items to acquire are the Antenna Switch, a Watt/SWR Meter, possibly a station microphone for the Flex-6300 and possibly a Neal Campbell FlexReady PC if I decide not to use the customer server style one I have.

The SkyNeedle, the HexBeam, the Collins Transceiver (with all the extra bits) and a second Palstar AT-Auto tuner were acquired for the new station; everything else came from my back up unit collection. The Expert Amp is coming out of my main shack as I will finally put in the Alpha-9500 that has been sitting in the box for a while.

I have power supplies and lightening arrestors to match my home QTH gear.

Down the road I will most likely add a 4O3A Signature Station Genius SSC-XL and replace the Flex-6300 with another Flex-6700 GPSDO/ATU transceiver to make the Northern QTH and Home QTH closer in design.

Eventually I would hope to share SmartSDR Radio “Slices” between the two QTH’s, with a long term goal of being able to remote one or both stations.

Now to get the Island QTH on the air while everything is put together, my SteppIR CrankIR Antenna with Flex-6300 setup, as used at Rocky Ridge Farm last year, will be pressed into action.

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

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:

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

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!
