Re: [Flexradio] Scope display missing??

[Dennis Petrich]

Sorry to bother the group, I solved the problem, I had the multiRX
slider/fader all the way to the right which seems to turn the scope off.
All is well now

Hello All,

My scope display is a flat line.  I have shutoff my 5000A including the
power supply and so far I have not been able to get the scope to work at all
and that includes the Panascope display.  All other displays work just fine.

I am running a 5000A with Core2duo machine running XP professional.  All
software is up to date with all updates and I'm running 2.0.22 using the
default display.  RX2 was off.  I thought the scope function was working on
2.0.22 when I first installed it but I don't remember for sure.  The scope
function definitely worked with 1.18.5

Thanks for reading,

I simply plugged the 1/4" phone plug into the 3000 front panel phone 
socket, then got a Radio Shack RJ-45 socket with press-on connectors 
(cost about $4 as I recall) and ran my mic power supply audio out 
into the RJ-45.  I used a straight-thru RJ-45 cable to connect the 
socket to the RJ-45 on the 3000 front panel.   Ask if you need more 
details.

I am familiar with the connector used by David Clark headsets. It appears to
have two rings but it does not. It is just the way that the connector is
constructed. If you look at the area of the plug where you wire to the
conductors you will find only three connections, including ground/sleeve.

[Mickey Baker]

Don't have a 3000, but if someone would send me one, I'd be happy to give it
a go! :-)

I plug right into the phones jack and into the MIC jack of my computer and
use VAC ro connect to PowerSDR. Works perfectly.No adapter needed.

Why solder on a plug if you've already got one in the computer?

Re: [Flexradio] Converting an Aviation headset for radio use

I chose not to replace the mic element for two reasons.

   1. I didn't want to lose the noise cancelling properties of the iriginal
   DC mic.
   2. I fly with it from time to time.

I've done that same thing at times with an electret element, and agree

against modern gear.


WA1QIX, who designs and builds class E AM gear and has one of the 
nicest signals I've heard swears by the little $3 radio shack 
microphone. Flat response, cheap, simple, same circuit as we've been 
talking about for the aviation headsets (which mostly use electrets in 
their microphones). Take what ever dead, pretty, microphone you have 
and graft an electret element into it and you might have all you need. 
Especially with the 10 band EQ in the Flex.


Heil mikes, music mikes, classic radio mikes, aviation headsets, 
inexpensive electret elements - isn't it nice to have choices?  :-)

get great audio and plug & play compatibility (or worst case, you or
someone solders a new connector on a mic). There are some very
good products, used & new, at great prices, if you shop the music, public

this marketplace (the D104's not).

The Flex has so much audio processing power, just about any mic can be

That's the standard GA setup.  1/4 for the headphones, .206 for the 
microphone and PTT.  As mentioned before, I think the helicopter 
headsets have a single plug with 4 wires (tip, 2 rings, and ground).



What I usually do when feeding a radio from mine is feed  +5 volts 
through a 1K ohm potentiometer to the hot side of the mic, then pick 
off the audio via a 1uf cap on the slider of the pot. I put an audio 
bypass cap on the DC side of the potentiometer and make sure the 5 
volt source I'm using is very quiet - usually I run 12 volts into a 
78L05 and a couple of caps to get a good, clean, quiet, DC bias 
voltage. Using the pot lets me adjust the audio output easily to match 
the radio's requirements.


I find I have to set the audio very low, otherwise a lot of background 
noise gets picked up, especially in the airplane. Using an audio taper 
pot helps in being able to adjust it to a good level for the 
microphone input. When you get it right, especially with the noise 
canceling mics, all you hear is your voice, nothing in the background. 
Not as much of a concern in the shack. :-)

Poking around some, it appears that a helicopter headset is a single
plug wired as:

tip  -- mic
ring 1 -- phones
ring 2 -- mic ground
sleeve -- phones ground

I've seen this referred to as a NATO Plug and Wikipedia  calls it a type
U-174/U or Nexus TP120.

http://en.wikipedia.org/wiki/TRS_connector#Aircraft_headsets

Standard GA headsets have two plugs, a 1/4" either mono or stereo for
the headphones and a .206" TRS for the mic.

That's the standard GA setup.  1/4 for the headphones, .206 for the 
microphone and PTT.  As mentioned before, I think the helicopter 
headsets have a single plug with 4 wires (tip, 2 rings, and ground).



What I usually do when feeding a radio from mine is feed  +5 volts 
through a 1K ohm potentiometer to the hot side of the mic, then pick 
off the audio via a 1uf cap on the slider of the pot. I put an audio 
bypass cap on the DC side of the potentiometer and make sure the 5 
volt source I'm using is very quiet - usually I run 12 volts into a 
78L05 and a couple of caps to get a good, clean, quiet, DC bias 
voltage. Using the pot lets me adjust the audio output easily to match 
the radio's requirements.


I find I have to set the audio very low, otherwise a lot of background 
noise gets picked up, especially in the airplane. Using an audio taper 
pot helps in being able to adjust it to a good level for the 
microphone input. When you get it right, especially with the noise 
canceling mics, all you hear is your voice, nothing in the background. 
Not as much of a concern in the shack. :-)

Poking around some, it appears that a helicopter headset is a single
plug wired as:

tip  -- mic
ring 1 -- phones
ring 2 -- mic ground
sleeve -- phones ground

I've seen this referred to as a NATO Plug and Wikipedia  calls it a type
U-174/U or Nexus TP120.

http://en.wikipedia.org/wiki/TRS_connector#Aircraft_headsets

Standard GA headsets have two plugs, a 1/4" either mono or stereo for
the headphones and a .206" TRS for the mic.

Re: [Flexradio] Converting an Aviation headset for radio use

[Gary Warner]

Brian,

OK, I think I understand.   It is odd that the Flex supplied adapter 
from the 8 pin mic connection only requires the use of two contacts to 
run my Heil for both microphone and PTT.   That adaptor must have some 
pins of the 8 pin connector wired together.


I will make a new .206 to 8 pin adapter.

So how do you connect the 4 wires on the .206" connector to your

It depends on how your adaptor cable is wired. Just a moment ago I 
sent the pinout for an aviation headset mic plug. It is:


tip -- ptt
ring -- mic hot (+)
sleeve -- ptt and mic ground (-)

GA aviation microphones are based on old carbon mics. They are low 
impedance (under 200 ohms) and require a bias supply. In  fact, they 
are identical to how Icom handles microphones and wiring up an 
aviation headset mic to an Icom radio is just a matter of a few direct 
connections.


In the case of wiring to the Flex you need to make sure you provide a 
bias supply (+5V at least) to the mic in the headset. So you need 
about a 100 ohm resistor from the +5V pin on the Flex mic connector to 
the sleeve on the headset mic connector. I also use a 100K resistor 
from the sleeve to the mic(+) input pin on the Flex mic connector. 
That should make everything work.


If you need more detail let me know and I will try to draw a schematic.

The microphone plug on your David-Clark (DC) headset really is only
tip/ring/sleeve. It only looks like it has two rings. Here is the pinout:

Tip -- PTT
Ring -- mic audio
Sleeve -- ground.

Now your DC headset does not provide PTT unless you plug in an additional
PTT between headset mic plug and the radio. Some headsets (AvComm) actually
have a backup PTT button on the headset itself so I always go ahead and wire
up the PTT part of the circuit.

There is but you don't need to solve it. The impedance of the aviation 
headset is very low and the output high so it will work into any 
transceiver without a problem. The major problem is to pad down the 
output level so that you won't overdrive the mic input of the radio. 
That just requires a pair of resistors.

Why would you need 1/8"? None of the Flex radios use that. Regardless, 
I built a cable with the proper .206" TRS jack on one end and the 
radio's mic plug on the other. The requisite resistors live inside the 
.206" jack housing. I need to carry mic ground (shield), PTT, bias 
supply (+5V), and mic audio to between the mic plug and the mic jack 
for the headset's mic plug.


I am making an assumption: that you are comfortable fabricating cables 
and soldering.

[Flexradio] FXpad released

[Giuseppe Campana]

Hi,

FXpad is released:
http://www.woodboxradio.com/download/Fxpad_v1_setup.zip

FXpad, the CAT software designed as an extra control panel for PowerSDR and
FlexRadio Systems transceivers, requires Tmate for proper working, however,
it also works without it but some functions are not available.

Fully functional for a trial period of 15 days FXpad gives, in a nice GUI
(designed for touch screen), the normal most used transceiver's controls and
adds new features such as:

- four scales analog multimeter (inherited from BobMeters)
- 4 dedicated DSP filters for each mode (fully programmable)
- direct control (with Tmate) of RIT - XIT - SPLIT and SubRX
- keyboard for direct frequency entry
- keyboard for 12 Macro CAT commands (DDUTIL style, by K5FR)
- direct control of VAC and I&Q out to VAC

FXpad requires high polling rate virtual serial port for connection 
to PowerSDR and

at least Windows XP with dual core PC or W7, to operate efficiently.

Fxpad, having been designed for touch screen, offering the best of 
himself in union
of HAMpad (the small USB monitor with resistive touch sensor) or 
others similar monitors.


Fxpad works with FLEX-5000, FLEX-3000, FLEX-1500 (with limited multimeter)
