Bonjour Clément, Fri, Jul 30, 2010, Baron Clement skribis: > I'm trying to control the pcr 2500 from linux. It seems that hamlib uses the same protocol for both pcr 2500 and pcr 1500. However the 2500 has two antennas whereas the 1500 has only one. Do you know if there is a way to switch from one antenna to the other on the PCR 2500 ? > Unfortunately, there's no official documentation from Icom about the protocol of the PCR receivers. For example, the PCR-1500 backend was developed as an extension from the PCR-100's and PCR-1000's, assuming the protocol was similar. Initial knowledge of the protocol was obtained by people doing reverse engineering under fair use. The PCR-2500 appears to be a double tuner, which is a new feature regarding the protocol. Luckily, its protocol has already been figured out[1] by the PCR2500 enthousiasts of the PCR2500 yahoo group. Kudos. I've developed an extension of the pcr backend, and you will be able to find it as model id 404 either in the SVN repository or in the daily snapshot[2]. Support for get_dcd (squelch status) and set/get_dcs_sql were added as a bonus. [1] http://groups.yahoo.com/group/PCR2500/message/914 [2] http://n0nb.users.sourceforge.net/ Clément, can you please test this backend with rigctl and report to this mailing list? Some directions can be found in the file README.betatester. Make sure you specify 5 v's(Continue reading)

to read freq and mode, polling once every second. And to occasionally set the frequency. So let's call it 'beta'.

Of course that is subjective. I would say that it works without issue
for the main desired functions. Other lesser used functions may or may
not be implemented.
