Ameritron ALS-500M Amateur Radio Mobile HF Amplifier 500watts
Ameritron Solid State 500W HF Mobile Amplifier. It is in fully working order. It comes with power cables (big battery cable type with massive fuses) to use with a car battery and original user manual. It does not have original box. I bought this to use mobile but never did! I set it up at home and powered it from my Brick 13.8V 120amp PSU. I had a couple of QSO's on 14mhz. But I could not get my V dipole to tune in corrrectly on the other bands and that is as far as I got with it. So not a great deal of use! I bought this second hand. If you need a mobile HF Amp this is the one to have. Here is what the manufacturers say. Ameritron mobile no tune Solid State Amplifier - Mobile no tune Solid State Amplifier - uses four rugged 2SC2879 high power linear RF power transistors. Instant bandswitching, no tuning, no warm up - just turn on and operate - makes mobile QSOs safer.
Very Compact - Just 3 ½" x 9" x 15 - fits in nearly any mobile installation; weighs only 7 pounds. Extremely quiet - quiet low speed, low volume fan stays off and silent until temperature rises. Output Power - 500 watts PEP, 400 Watts CW Continuous Coverage - 1.5 to 22 MHz 10/12 Meters with easy to install optional kit.
Load Fault Protection - disables and bypasses amplifier if antenna has excessively h high reflected power or if bandswitching is set lower than exciter frequency - virtually eliminates damage because of operating error; has Load Fault LED indicator. Thermal Overload Protection - disables and bypasses amplifier if temperature is excessively high; automatically resets when temp drop to safe level Thermal Overload LED indicator. Excellent harmonic suppression - multiple section output network, push-pull output circuit has excellent harmonic suppression. DC current meter lets you monitor collector current.ON/OFF Switch - bypasses amplifier for "barefoot" operation without having to disconnect high current power supply cables. Remote ON/OFF Control - lets you remote control ON/OFF function for out-of-the-way mounting of amplifier. Exciter Drive - less than 100 watts input gives full output. Power Supply Requirements - requires 14 VDC at 80 amperes peak current for PA transistors and separate line for 14 - 16 VDC at 4 amperes for control and bias circuits. I will be posting this but if you are the nervous type and want to come and collect it from me that is fine.
