Hey @Pierre-P
Yeah, you would need a new gateway for each radio type.
I found a new mysensors page ! here:

Advanced initialization
It's also possible to construct an instance with RFM69 radio driver and/or enable signing support. You can choose one of the following radio drivers:
MyTransportNRF24 transport(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW);
or
MyTransportRFM69 transport(RFM69_FREQUENCY, RFM69_NETWORKID, RF69_SPI_CS, RF69_IRQ_PIN, isRFM69HW, RF69_IRQ_NUM);

Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch.
We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)
It has been a long time but I’ve learned a few things that I wanted to share.
This library of information (Thank you NeverDie and others) has been so helpful in my hobby developments.
Software Defined Radios for signal analysis. With the help of Andreas Spiess explanation of IQ transformations, I learned about Software Defined Radios and I bought one (RTL-SDR). Using this I can clearly discriminate between effective 433 MHz transmitters and bad ones. Not only is the signal density displayed on the software (SDR#) but so is the frequency.
Power Profiler Kit II has been indispensable in watching power usage and seeing into the details of the radio transmission. In effect this thing has saved me from buying an oscilloscope for my simple little bench.
Tonight, I saw this video: https://www.youtube.com/watch?v=Z9nycymUd-I It describes common PCB errors. It is too advanced for me, but I did pick-up a few ideas about ground planes (tip #6 from the video).
I hope this is of some value for folks.
