# PCB size 75 x 49 mm up to our analog sequencer boards.
# The entire control needs to be done by a small PIC 12F629/675, to save space on the board (the 12F series has only 8 pins, but that only 6 possible I / O ports for input and output).
# A memory is sufficient, but the speech must be switched into a loop.
# Recording and playback of the message should be signaled by an LED.

The AmQRP "PIC-EL Kit" is a multi-function PIC16F84A-based project board designed by Craig Johnson, AA0ZZ and the American QRP Club for experiments being conducted by John McDonough, WB8RCR in his online PIC Elmer 160 course. The course material is geared around use of common I/O components — pushbuttons, LEDs, LCD display, rotary encoder and speaker — and experiments are designed to take the student...
Standalone SDR transceiver ... no PC, portable, compact
Self-contained single band ... based on the I/Q RF front end
Softrock-compatible ... designed to interface with SR v6.3 RXTX, etc.
Low Power ... 90ma (Cube), plus 100 ma (Softrock Rx) or 300 ma (Software Tx)
Add-on RF Amp & Attenuator ... good control of incoming RF, optimize some SR features.
Quadrature Sampling Clocking options...
