The Best Thing About My ACOM 1000 Amplifier
#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.
Thank you

I also have an acom 1000, great linear and so easy to tune.
Hi Michael,
Thank you for visiting and for commenting. I was really looking for a solid state amp, but when this one popped up I couldn’t resist. I am glad I got it. Fantastic amp!

Tha is for the gear report. Will retire soon and would like info .on a mobile 10 thru 40 meter antennae. Gave one to a ham that was full time RV years ago and never got it replced.
Hi Steve,
Nice to hear from you and thank you for commenting here. I think the best overall mobile antenna is the TarHeel. The 200A is an excellent choice if you have the space for it. I have a 200A https://k0pir.us/vehicle-bonding/
Hi-Q makes some good antennas too. I still have this one and it will be mounted on my camper someday https://k0pir.us/hi-q-5-80-mobile-hf-antenna-installation/
If I had an extra 1k I would get one of these Scorpions https://www.scorpionantennas.com/mobile-antenna_c_18.html
Thanks again have a great weekend and best 73,

Really informative, thanks for sharing this!
Hello and thank you for commenting. Your input is greatly appreciated. Best 73! – Rich, K0PIR
I couldn’t find the pictures on how you changed the voltage on the Acom 1000? Thanks -Tom
Hi Tom,
It’s nice to hear from you and thank you for commenting here. I failed to upload those pictures earlier and I’m traveling right now so I don’t have access to them. Sorry about that, but if I remember correctly the diagram is on the inside or rear of the amp. Again, very sorry. The last thing I did was replace the tube and I think I took pictures of the voltage changes again when I did that, but again I don’t have them. I’ll be home in a couple weeks, but until then you should email their tech-support. They are very timely and very helpful. (acom@acom-bg.com)
