73, Les Rayburn, N1LF The timer function it has allows you to start recording at any time, for a selected number of minutes and to repeat at a selected number of minutes. So you could start at a set time, record for 5 minutes, then repeat every hour. The downside is that it appears it would repeat forever. You can set up a non-repeating recording, but it looks like you can only set up 5 of these. Maybe others know more tricks. HDSDR is also a good choice - and it looks like you can set up 10 or 20 or more recordings, and have them repeat daily. So you would just get the times you want. You could have every other hour record a different spectrum - if you wanted to cover more than 19 or 20 channels per night, but only every other hour for a particular band segment. Or set up schedules that shift up 200khz per day and cover the whole band in a week or so. So HDSDR is more flexible as far as setting up specific times, but SperctraVue would be easier to set up if you are OK with having it record more than just the timeframe you mentioned, or manually stopping it. If you have a lot of disk space it wouldn't be a problem that it records during the day too. I think you should allow more than 3 minutes on the hour - I think the FCC recommends stations ID within 3 minutes but the requirement is flexible depending on the kind of content the station is transmitting. For some content they recommend within 5 minutes, but even that is not a hard requirement. You might want to record +-5 minutes but you know your disk space limits. Are you aware of the "mwoffsets" google group? They have data about the carrier offset for many stations which can help in identifying one out of a crowd. In some cases you can pretty much ID the station without ever listening to audio. I use SpecLab to view carriers down to a small fraction of a Hz. It's kind of cool to see 20 or more carriers at once. Craig - N6IO On 12/17/2013 9:25 AM, Nick Hall-Patch wrote:
