60m Transceiver
The 60m transceiver has the following features
- Channelized operation
- LCD display
- Frequency
- Mode (SSB / CW)
- Modulation Source (Mic/Key/Data)
- RX / TX status
- 9MHz IF with Xtal filter
- SSB & CW set via mode switch
- Approx 3W PEP
- Digital mode input/output and PTT via 9-pin D
- SSB Mic input via 8-pin round “Icom” connector
- Modulation Source (Mic or Data) chosen via select switch
- Scan start switch - scan a preset group of channels - cycles continuously, no “squelch”
Arduino Versions
There are several different firmware versions….
RX Only, with CW / SSB, and scan
