The Best Thing About My ACOM 1000 Amplifier

I recently picked up a used ACOM 1000 amplifier in great condition. Since I don’t have 240V in the ham shack I rewired it for 120V. I’ll show you how I did that later. The ACOM 1000 has many great reviews and many great features. I’ll tell you what I like best.

#1 It’s Easy to Tune

The best thing about the ACOM 1000 is I can tune it in 5 – 10 seconds. It is so easy to tune because it uses a feature called TRI. I just followed the instructions. 5 – 10 seconds, that’s it, no fuss, no worries.

Tuning is substantially simplified by a plate-load True Resistance Indicator (TRI) and by an automatically controlled input attenuator. Operating parameters are displayedby a multi-functional backlighted Liquid Crystal Display. Full break-in transmit/receive switching (QSK)is standard. – ACOM1000 Operating Manual

Wired for 120 Volts

I haven’t been running more than 550 watts, so I haven’t had any trouble using 120v. The circuit in my ham shack is a 30 amp circuit. I’ll post some photos of how I did the voltage change. It will be easy enough to change back someday.

In the video below I’ll show you how simple it is to tune.

NOTE: I use a 15ms TX Delay in the Icom radio.

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.
