MA3 Improvements: HD2 Testing

The first AM HD2 was tested on WWFD in December 2019
Program Service Data (PSD) and a Station Logo was

transmitted as well

Signal was received on an Xperi test receiver
Proof-of-concept demonstrates flexibility of MA3 system
Possible FM translator implications for AM stations

SLIDE 17

On Nautel NX series transmitters, it’s as simple as turning it on

MDCL - AM Power Savings

Several

algorithms

Varying levels of

compression

Impact on signal

also varies

MDCL

SLIDE 20

Pros:

– Significant power savings – Potential reduction in peak voltage means lower

perating voltages (less stress
n antenna components)
Cons:

– Can impact range and signal quality – Peak voltage can also be increased – depends on algorithm

Play Safe

More and more, the new normal will require working alone at the transmitter

site. Please make sure you have proper

protective equipment and tools to work safely!

SLIDE 40

Maintenance Run!

Transmitter sites – the ultimate in social distancing

Air filters
Generator fuel, oil, filters
Check breaker panels for

warm breakers

Check ground connections
Fencing
Groundskeeping

Don’t leave the keys in the lock

Password is not a password
If it can be seen, it’s a target
Passwords are like keys…

– Have spares/backup systems

VPNs are inexpensive
Air gaps work best
Have a sacrificial machine
Don’t leave the defaults active
