Hi Allard: I think I side with Ashhar on this. True, the update() method of the EEPROM object only rewrites the data if it has changed from what's currently at that EEPROM address. If I'm engaged in a long QSO, this works fine. However, if I am just "tuning around" looking for someone calling CQ or am looking for a hole where I can call CQ, if I do this for 10 minutes, (which I do a lot when I operate QRP) I perform 60 EEPROM writes for no real reason at all. The next time I turn on my BITX40, I return to whatever random frequency I may have been on during the last 10 seconds before I shut down. It might make more sense to 1) opt for a much longer delay, or 2) throw it out altogether and replace it with 5 or 10 ?"Favorites Frequencies" (i.e., net control, repeating sked with a friend, watering holes or QRP frequecies, etc.). That way, when I turn on the rig again, I come up in a place that makes some sense rather than a random frequency. Saving a random frequencys would make more sense on a multi-band rig, such as the pending microBITX. However, I will probably code a Favorite Frequencies. The frequencies could be hard-coded at compile time, although it would not be too hard to code it for runtime changes. Because I am using an encoder for frequency tuning and menu selection, I could scroll through my "favorites" list and select the one I want and immediately jump there. It might even be faster than just tuning to that frequency. Just a thought...

Yes I'm aware of this. That's why we use the EEPROM.put command which uses EEPROM.update() to perform the write, so it does not rewrite the value if it didn't change. 73, Allard PE1NWL On Thu, April 27, 2017 18:10, Ashhar Farhan wrote: > The eeprom has limited write cycles.
