39253Re: LO Question
- Jan 2, 2010Hi Bob,
Initially, I had removed the dip sw and the PIC and connected via USB/i2C adapter, but using PE0FKO CFHGSR software, the SI570 factory settings button is grayed out, so gave up. However, the LO appears to be working.
When I set the 746 signal to 7010. the Rocky readout is at 7019.9, so it does appear to be fairly close. However, I still have little sensitivity. I do see my 746 signal when I key in AM @ 5 watts out, but have not received any other signal to date.
