There are / were two 30 M frequencies in Europe because there were two different server networks one the regular PSKmail and the other more orientated to sailors which included the transmission of weather bulletins etc.. Re the convention of dial or centre frequency. Centre frequency allows the user to work out how they will match the listed frequency and is all they need to be sure. Dial needs to have the audio frequency included in the information for the user to be absolutely sure EG dial 10.147 MHz + 1500Hz (from your revised listing I'm guessing you are using 1000Hz). On a quiet band it should be easy the see the signal in question on the waterfall (assuming a narrow filter is not being used) but on a busy segment it might be a bit harder. But given some modes work in the noise it then becomes more important for both stations to be sure they are in the right place. Either method works as long as all the required information is listed On 31/01/12 22:09, Bernard Dekok wrote: > OK, > > *Center freq:* > > Day 7.118.0 USB > Night 3.596.0 USB > > Not sure how this is less confusing...=) > > I skipped Packet radio.... > > Why do we have have both 10.148 and 10.147 MHz advertised in Europe.
