ACOM A2100 HF/50 MHz Linear Amplifier

Easy to operate The TRI is a powerful tuning aid that, together with the automatically controlled input attenuator, helps the operator to quickly and precisely match the antenna impedance to the optimum tube load impedance (5-10 seconds typically). The auto-operate function (when enabled) maintains the amplifier in the OPERATE mode for you, thus avoiding unnecessary…

Dealing With Noise in HF Mobile Installations

Many hams find that their HF mobiles receive more noise than they do usable signals. Common noise sources include the ignition system and alternator. Spark plug noise is propagated through ungrounded body panels and the exhaust system, which is normally suspended from rubber vibration dampers. The rubberized supports insulate the exhaust from ground, essentially creating…
