Re: TNCPi WITH YAESU FT 7900R
That's not quite correct. For receive, the difference
between the 1200 and 9600 ports on the rear socket is that the
former has de-emphasised audio while the latter has "flat" audio
from the discriminator. There are reasons why using the
discriminator output for 1200 packet is often superior for many
hardware TNC/modems that aren't smart enough to compensate for
relative tone levels (1200/2200Hz) when they are wrong. Soundcard
style modems like Direwolf are far more capable and less particular
in this regard. If you want to know why the correct audio is
important, take a look at this site with pictures and a very simple
explanation.??
I know I flog that site and will continue to do so because if
everybody using packet read that article and implemented correct
audio practices there would be a lot more stations having much
greater reliability with packet radio/APRS communications. If I
sound like a grumpy old man, I am. I've been involved with packet
since about 1985 and the biggest single factor for people's
woes and failures with the mode remains wrong audio setup.
For transmit when using the rear socket, the radio will probably
select the right option depending on whether you choose 1200 or 9600
for the speed in the radio setup, like my Kenwood TM-V71A does.

You need to use the 1200 port on the radio. The other is for high
speed packet and won¡¯t work with a TNC that isn¡¯t made for it.
Otherwise all is good.?

Try uncommenting the the following.? Try the first one and see if that works, if not uncomment the 2nd one as well.
# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1
# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

that's one of the first syntaxes I used. The yellow light is flashing on the Pi Hat. All of the lights blink when power is applied.
Putting it to bed for a while. If I plugged my USB tnc-x I get it to start in not type.

Had a similar problem with a Pi 3B.? Ended up buying one of these to boost its signal.? Works okay with this.
Bit of a pain for portable use as it's another device to tote, plus extra HDMI cable, etc.? Does fine at home.

hmm could we get such a thingy run on a pluto??
yes i know not a raspi but it is a linux box (kind of) ... and a
wideband transceiver
here in germany a few guys planning to make the pluto a user
access point for hamnet ... THAT could be really a nice idea for
replacing the packet net (or the rest of that we still have) all
to hamnet ...

Downloaded It.
Now wanting to run it as a WSPR node, with SDR Play RSP1 .
Will it be plug and play? ?
Will i need any API to be installed for SDR Play ?
Also any pointers as to how to route the audio from SDRPlay to WSJT X for input to run the WPSR Node
You're welcome.
There are two ways to run WSPR on the HamPi image "out of the box". One is to run the "wspr-pi" application in /usr/local/bin . The second is to run WSJT-X.
The SDRPlay is receive-only. You can not use it to send WSPR.
The SoapySDRPlay drivers have been installed on HamPi. This allows you to use the SDRPlay with GQRX and CubicSDR, for example.

Re: TNCPi WITH YAESU FT 7900R
I bought my cable from Hammadeparts.com (and ebay).
Works fine. I have not used it in a while as I created the setup for Emergencies
then packed it nicely ready to go out the door.

Rob,
I have a 40" Vizio TV I bought 11/19.? I had a similar issue with it not detecting an input signal.? Discovered the TV is just too smart and is picky about inputs with the default settings, but if you disable "CEC" under "System", then it works as expected.? Take a look at what's under "Menu" on your 32" TV and see if you have this parameter.
