?Hi all,
?
I have been trying to reduce the drift on my wspr tx when running 5-6 bands. I seem to be able to get one band with zero drift and the next band in sequence has some drift. See the data for 20m versus 30m below
?
I have attached a small heat sink on the 27mhz xtal as suggested but am wondering about park mode. U3S is also in a qrp labs case.
?
If I set to mode 2 and say 149.000.000 as suggested it doesn't change much.
?
Would I be better to use park mode #1 and then 149.000.000 for a frequency.
?
