Like Jim, i just used my little nippers.  I cut short cut first (about 1/16th
inch) and them the longer cut and the corner snapped right out leaving a nice
square notch.

My controller worked first time.  I am still making pods.  I marvel at the
completeness and professionalism of this project.  I have a hard time fathoming
the amount of time it took Jim to design, document and kit this unit.

I always wanted a Dremel tool ! 

 

I bought one on the way home today and took  15 seconds to smoothly cut off the corners. 

 

Thanks !!

I spend my time working on boatanchors so assembling the SPII is kind of new
tech for me hihi.  For the IC's on the microcontroller board like the dual
decoder or octal buffer... why not first solder in a dip socket and then just
plug these in?  I guess these never get zapped and need to be replaced?

Jim,

I am assembling the board with the replacement RJ45 from MOuser - 571-6116202-1.
It creates a very tight fit with the plastic feet so I shaved those a bit but
the footprint is about 2mm over the board's silkscreening on the inside
(parallel and opposite from the edge of the PCB).  So when I test assemble the
board and screw it down the edge of that RJ45 that is over too far rubs hard
against the inside edge of the cutout and it gets pulled off the PCB as I
tighten the relay board. Some pins at that point barely are making thru the
holes so I am reluctant to solder even not minding the RJ45 looking pretty darn
crooked hihi.   It's not the SO-239 as they are all loose and have plenty of
jiggle room.  I think this RJ45 footprint is not an exact replacement from your
original specs.  Any advice appreciated.  Help !!

I hate to screw that super nice paint job on the coax box by filing the edge...
how come you didnt do something as nice for the front panel??

I will order a few of the original part # and another 1-2 of the new ones -
small price on top of the investment already... just more time to wait.  If that
doesnt work then its a file and cosmetics come second.

Why 2 BNC's for RF sampling... the manual shows one that seems to be sufficient?

Oops...dumb question - i missed the Vin option as well as the Vout.

Sorry for the bad posting

Just looked for original and substitute -- neither available -- any other
thoughts on what available part from Mouser would work.  Thanks

Jim,
I briefly discussed this problem with you in Dayton in 2011 but at that time I
have not quite thought the problem through. I am only getting to implementing my
StationPro II now. Here is the problem again:

I use a SDR-IQ as a panadapter in a somewhat unconventional way on my radios.
The SDR-IQ is fed from an antenna splitter on the RX only line on all 3 radios.
This means I need a second RF switch unit in parallel without the amplifier
switching part that will switch the SDR-IQ input to each of the radios.
Initially I planned to implement this by means of an Ethernet splitter that
takes the RF unit control signals to a home brew board with 3 relays that drives
a 3-way 24V coax relay (which I happen to have) - then I noticed the StationPro
"networking unit" that will actually do what I want to do without having to mess
with 24V.

There are a couple of outstanding questions:

1. Will the Ethernet cable and circuitry handle 2 units in parallel. I think the
relays pull about 35mA - so we are talking about 70mA which sounds reasonable to
me.

2. I will obviously have to make a RJ-45 to RJ-25 interface cable. I already
have a commercial Ethernet splitter that just plugs in - so no mods or fancy
Y-cables needed.

3. I guess I will have to ask Harbach how much they will charge for a networking
unit since I do not "qualify" through the normal channels.

Any reason why this would not work or any better ideas?

Hi Jim,

I got the Network PCB in the mail today - Thanks much. I cannot seem to find the
cutting template for the enclosure that you refer to in the Network Manual. Do I
download it from somewhere?

Thanks again & 73,
Sebastian - NS0W

I have a Station Pro II that I built about a year and a half ago.  Both mic
connectors are wired for Yaesu.  Reason for selling - downsizing to one amp and
one radio. Contact me at paul at paulmandel dot net if you are interested.

As you can see in the previous posts, I needed a secondary antenna switch to
have my SDR-IQ panadapter follow the radios. I realized that the "Station Select
Relay Unit" as described in the SP II Network manual is the ideal candidate for
the RF switching. Since this is being used for Rx only, I built it with BNC
connectors:
http://swessels.org/main.php?g2_itemId=3957

I noticed on the schematic that it would be easy to route TRX1, TRX2 and TRX3 to
the J03 - remote out connector. We already have the connection to J03 on the
jumper block. I ran some wires from U204, pin 16,17 and 18 to the jumper
connector:
http://swessels.org/main.php?g2_itemId=3954

The SSRU was connected to the main unit with a standard 6 wire, RJ-25 cable.

It is pretty cool to be able to select rigs and have the panadaptor follow the
rig.

The only improvement that I could have made to this, is to have the power on the
SSRU drop out when PTT is activated to have more RF isolation during transmit
but I could not come with a neat way of doing this - so I just wired my old RF
isolation relays in series.

Thanks to Jim for supplying the SSRU PC board and even more thanks for coming up
with this great product.
