Re: Problems on startup

Hi Boris,

1. Check if the IDC cable is properly installed, and check if the rotary encoder is properly reworked.
2. 1678 current is high about 50-60mA, so hot is normal. Can you hook a scope to pin 5 of 1678 to make sure there is output without touching pin 1? Can you make sure the PLL is locked well? Can you check the soldering nearby?

I assembled and powerd up the KIT and now I have two problems:
1. I can't change frequncy whith the knob, it goes just 1 digit from the starting frq.
2. I can here RX only if I tuch resistor 330 on pin 1 of 1678 SMD on digital board and the chip gets very hot.

Any ideas will be helpful.
