11055Re: RXTXv6.1 kits status March 31.
- May 6, 2007Suggestions:
1. optional circuit at the first FF (JP1 pin 2) to drive the board
with a DDS60. The curcuit needs 50 ohm load, coupling cap, and two
100K bias resistors to set input at Vcc/2.
2. PTT out goes 0 to 5 volts. Would like an option for open drain PTT
3. On-board Xmit LED.
Some day I would like to see a vfo and phase detector in place of the
crystals for use with a DDS.
