DCF77 Time Signal #display #t41 #t41-ep
|
The time field on the display is set to 12:00 whenever the radio is powered up. There is no provision to set it since we did not require the battery necessary to maintain the correct time. However, the Time library does provide a function (setTime()) that allows you to set the clock's time. Obviously, for this to be useful, you need to provide a battery to maintain the time while the rig is turned off. Jack, W8TEE

A review of the code seems to imply the T41 time shown in the display should sync up with the DCF77 time signal, but I've never seen that happen (I live in Phoenix). Should it? If so, is there a way to have it sync up with WWVB, which is more accessible in my part of the country? I couldn't find any messages on this topic and haven't seen anything in the book (first edition), hence my question. I have a GPS module I could use to do it but wanted to ask the group first before I move in that direction. Thanks, Paul (KI7LW) -- Jack, W8TEE |
开云体育Ive seen most of the other radio groups clammering about adding a real time clock module to their radios of late. ?I suspect, long term, this is the teal answer. ?Dr.?William J.

Harry: I think a good number of people will opt for a RTC. Are the issues such that I might help? Jack, W8TEE

Jack and Paul I have a modified version of the direct frequency entry software which allows you to set time and date.? I tried it out on a couple of? 'volunteers' and they identified a few issues which I've not had time to sort out yet. Would that be helpful assuming I can sort out the issues they raised? Harry GM3RVL -- Jack, W8TEE |
