Having devoted a significant amount of time to thoroughly understanding the
ART-13 functioning and putting it in operating conditions, I wrote an
essential - though detailed - guide for those not wishing to read the 400-page
maintenance book which is not very explanatory and contains a lot of unnecessary
information for ham radio purposes.

"All What You Need to Know to Put an ART-13 Transmitter in Operating Conditions,
Paired to a BC-348 Receiver"

In the paper you will also find:

- building an AC power supply for the ART-13
- fully reversible modification for zero-beating the transmit carrier on the
receive signal
- fully reversible modification for avoiding the transmit relay to loudly
chatter when operating CW
- matching 50-ohm antennas on the low frequency bands
- building an AC power supply for the BC-348
- building an no-zero drift S-meter for the BC-348 receiver
