Changing the VARA mode

Lee Bengston All Messages By This Member #42244 Hello, To provide an example, I'm scanning both 20m and 40m during the day, and the same BPQ port for VARA applies. The default mode is BW500, and that's needed for the 40m frequency. On 20m I could potentially use 2300. Is it possible to specify the VARA bandwidth in a connect script? If not, is there any recourse other than to use a different radio and VARA instance for 20 meters? I suppose I could just change the default to 2300 and let it adapt to incoming connections that use 500, but there's the risk of an incoming connection on 2300 that could cause problems. Any advice would be appreciated. 73, Lee K5DAT

Thanks Mark! ? Be sure and check to allow 500hz connections in the Vara TNC settings.? It has always worked for me. Yes, up until now I've been running VARA 500 exclusively, so that has been checked all along. ? 73, Lee K5DAT

Format is BW500, BW2300 or BW2750 and for VARAFM FM1200 or FM9600. If you include a BW command in the port config the TNC will start in that mode and return to it after a session. 73, John On 01/10/2024 15:23, Lee Bengston wrote: toggle quoted message Show quoted text Hello, To provide an example, I'm scanning both 20m and 40m during the day, and the same BPQ port for VARA applies.

Also I see one can override the port default with the VN, VW, etc. parameters in the scan lines. That's great as I have some frequencies where I don't want to accept VARA wide and others that I do. 73, Lee _._,_._,_
