Yep, depending on the pi.  Pi 3B requires 2A, 4B+ pi foundation says 3.5A.  add to that any USB devices and what they pull up to another amp, then you need a powered hub beyond that

If I power the pi off of a 5v cellphone battery pack, noise drops down (seems like maybe a little, but at least S6 floor drop). As I say, I tested this pi in close proximity to the radio before off a wallwart, so I don't think pi itself is creating the noise.

Re: 12v->5v noise

 

A Raspberry PI 4B can only accept 3 amps on it’s USB-C connector.  It does desire 5.1V though, not 5V.  
It’s tricky finding a 5.1V USB source that isn’t 110VAC powered.  

I have been using a switcher supply made by DROKing in the far east. 
This is a $15 or so device which has a multi-turn pot to set the output voltage and accepts a wide range of DC voltage on the input.  
A key feature is that when main power is turned on, the unit immediately outputs the desired voltage to the USB connector.  Some of the variable output USB converter items power on with the USB output disabled.  

The bug with this particular unit is that it appears that DROKing has discontinued it in favor of a menu driven device (at the same price) but which powers on with the USB output disabled.  However, the unit continues to be available in various places including Amazon.  However, for a while the ISBN number kept changing and so any link to the offering seemed temporary.  That sounds like somebody is cloning the device and it isn’t DROKing anymore.  Dunno.  Maybe DROKing changed their minds when the Internet blew up after they discontinued it?  


cc_buck_converter_pi_supply

I haven’t had any particular noise on HF from this, though I live in a suburb and have plenty of noise already.  YMMV.

Re: 12v->5v noise

Pierre Martel
 

A pi4 need 3 amp just to run normally. not talking about any device powered by the USB or other power connector on the pi. 

A LM7805 will supply 1 amp max continuously and this is with a pretty large amount of dissipated power. If you go from 12v to 5v. just make the calcul of the power that it will need to dissipate. At 1 amp. 12-5= 7 volt times 1 amp = 7 watt that need to be dissipated.  I would go with a better designed buck converter circuit that will dissipate less power. and i would filter it a lot more by putting it in a grounded metal box with ferrite on the input and output wire and with small capacitor like 1uf or 0.1uf at the input and output also.

Re: How to set up TNC-Pi9k6

You need to go into raspi-config, go to interfacing, select serial.  Select no for logins, and yes for hardware. 
Then do "ls -l /dev/ser*" to see what serial ports you have and what they are linked to

The problem I ran into is that gpsd changes the mode of the GPS I use, BU353S4, so that it sends binary rather than NEMA.  This can be reversed and gpsd can be told to not change the mode.  I documented how to do this in the YAAC-users forum at https://groups.io/g/yaac-users/message/544

For the power shortage I took the 2.5 amp, 5 volt power supply for an old Roku device and changed the end to the proper USB plug. I did install the newer Buster version of the OS anticipating JS8Call. The CPU usage graph shows it at nearly idle even with a full fldigi decode going on.The Pi seems to have plenty of power for that use.

I had to experiment with the audio output "volume" settings for the transceiver "audio" (called CODEC on my Pi) until I got a decent waterfall level. Then the decoding went well. That need to change the audio seems to depend on whether flrig or fldigi in controlling the transceiver.

Re: GPS Puck for time

Greg Engle
 

The GPS is working and I'm decoding WSJT-X FT8. Issue was the GPS wasn't outputting NMEA. Easy fix with a utility (SiRFDemo)
But now I can't transmit.
The radio keys but the SignaLink isn't going into TX. Since the audio is coming from the SignLink and decoding, it's 1/2 right.
Since I'm at a decent point to backup, I'm doing that!
More trouble shooting!
