Some Additional 4o3a Rotator Genius (RG) Notes

The 4o3a Rotator Genius (RG) I’m setting up has a few idiosyncrasies worth mentioning:

  • Initial setup required a male-to-male USB cable or manipulating the buttons on the bottom of the unit to enter the menu system and a static IP address.
  • (This applies when contrasted to AG v 1.0, as AG v 2.0 uses a different connector) The Eurostyle Terminal Block for DC power is opposite polarity of the same plug when used in a 4o3a Antenna Genius.  You can also power the RG with up to 48VDC.  Output to the Rotator control cable is adjustable in coarse increments to lesser amounts.  (Remember to calculate and then check your voltage at the rotator end of the cable. – you’re going to want 7v or higher at the sensor end.)

Some 4o3a Antenna Genius (AG) Notes

  • With AG v 2.0 the DC power connector changed, perhaps to make room for the OM Module connector (OM Modules are an accessory relay board).  I own both v 1.0 and v 2.0 AG units. Here are pictures:

Preparing the 4o3a Rotator Genius for the Skyneedle

The “K9ZW Home”QTH’s Skyneedle is getting a 4o3a Rotator Genius azimuth direction detection and rotator control system. The rotator is an AlfaSpid RAK rotor. (Links to my suppliers towards the end of this piece)

I’ll call the “Rotator Genius” an RG for short, is a relatively newer offering by Ranko’s 4o3a firm that also produces the Flex co-marketed Power Genius XL amplifier (PGXL), the Antena Genius intelligent antenna switch (AG), and the Station Genius shack automation device (SG) I’m also using in the shack.

Here is the controller part of the RG:

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

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!

What is that holding up my Power Meter? FlexRadio Systems 4o3a Power Genius XL Amp!

 

Alpha Power Meter Stand?

Good News:  My FlexRadio Systems Power Genius XL Amp has arrived and is working great!

Not So Good News:  I am having so much fun that I won’t have much extra time to blog about the experience until next weekend.

I’m doing a lot of exploring with the new amp, given my time limitations.  As you can see in the picture there is no problem putting out the power.   I’ll post some statistics once I have a good systematic run through the bands.

I’m thinking I will also have a Flex-6600M very shortly to pair with the Power Genius XL Amp!

More when I get time.  Kind of wished I had more free time this week, but alas something has to pay for radio pleasures.

Not So Good News:  I am still at work.

I’ve walked up to look at the box 3-4 times so far.

Guess I know what I will be preoccupied with at home tonight! Setting up the Power Genius XL Amp!
