Good source for LPF for RaspberryPi transmitter is http://www.kitsandparts.com/index.htm Click on “Place Order” and go down to item 12, This design has the needed low insertion loss to keep

Do you have a schematic for a more minimalist (less parts) bpf or lpf only? Whats the power output unamplified when you just hang a wire off gpio output? Is the amp somewhat required after a filter to

Have you considered making a PCB of this circuit that would attach directly on top of the Raspberry Pi? You would have to decide on the model B or B+ as the layout is a little different. Any idea as

Hi, it is essential to add a low bass (or band pass) filter to reduce the harmonics. The raspberry output contains high odd harmonics, up to many hundreds of MHz. You can search the web for online

You will certainly need a Low Pass Filter. Good luck and 73 Clive GW0PPO

What needs to be done to a stock pi with this program(nbfm) to be legally used on the ham bands? Including additional narrowband configuration or low pass filters? I want to build a fox hunt

I want to make a fox hunt transmitter on 2m vhf band. Does the current software require a low pass filter to reduce harmonics? Can you show me what you guys use as a low pass filter or antenna setups.

How do you reduce spurious emissions/harmonics for ham use and ensure output is indeed narrow band. Do you use a low pass filter? Do you have a good link for a low pass filter to use for this project

Thanks for the direction. I have emailed him more times than I can count and he has been outstanding with help. I am to the point in trouble shooting that I believe it is the PIC on the TNC. A new

Well I got the AX25 working, Kind-of. The services work and I can get the calibrate data frames sending to the PIC on the TNC-black but no further. Still not TX. Has anyone got one of these

I use MobaXterm. It's free allows you to XFTP, Telnet, SSH, and even remote desktop. Jay KF7ITF

This is another video in which it is shown how nbfm and the TX-CPUTemp.sh script work as voice and/or packet radio telemetry beacon. http://youtu.be/a6ZHp92llYE http://youtu.be/a6ZHp92llYE

First things first - what version of linux are you using. If Raspbian, take a look at the tutorials at (for example) https://www.modmypi.com/blog?page=3 https://www.modmypi.com/blog?page=3 or

sshd supports SFTP. WinSCP is just a different client, and a more limited one at that.

sshd is on by default, simply use winscp or putty from windows. google search and download for windows.?

There is no reason to have to torture yourself with command line FTP. Google "filezilla client download", download it, install it, run it. Then click on menu... File->Site Manager... "New
