Select your final band of operation and repeat the procedure above. Good luck in your efforts. Keep it in standby and tune with just your radio.

The only draw back to the is the amp problem. The power supply will safely operate from Vac in the Vac position and in the Vac position. You may find that you have to vary the position of the inductance switch a position or two either way to get your best match. Fan speed is regulated by temperature sensors, assuring minimum noise for adequate cooling. Thats excellent high voltage regulation!

When I first set out to hook up my rig to the amplifier it stumped me. Re-tighten the knobs, replace the tuner cover and you're ready to go. But it gets even better than this!

Control your amplifier directly from your rig! Just turn on, select band on your transceiver and operate. Ameritrons exclusive Multi-Voltage Power Transformer lets you optimize for different line voltage.

The other meter switches between high voltage and plate current to warn of abnormal conditions. They not only are more difficult to cool, lol matchmaking unbalanced if one transistor fails they all have to be replaced. Instructions from both manuals are confusing. An optional interface cable is required for your particular radio.

At Ameritron, we dont just ship amplifiers we build them to last! The manual only shows how to connect an Icom amplifier. The relay provides a mechanical closure to ground on transmit to trigger the amplifier. You just learned how to hook it all up! This only addresses the hookup needed to trigger the amp.

In some antenna tuners the inductance switch is replaced with a continuously variable inductance, popularly known as a roller inductor. Adjust microphone gain and microphone compressor to keep the meter reading in the shaded area. The operator-friendly layout fits nearly any station configuration. So I figured, internet funny why not go to the experts the store that sold me the amp. This concentrates all of the heat in one small package.

Just took a lot of poking around. Your radio puts out W and in most cases it's not enough to overdrive the amp. Over-power protection enables if output forward power or reflected power exceeds a safe level. They are mounted on the dual heavy duty heat sink and properly arranged to spread out the heat over a large surface.

Operator-friendly layout fits nearly any station configuration. In layman's terms, all a tuner does is act as a kind of adjustable impedance transformer between the radio and the antenna. The tube is covered by the tube manufacturers warranty.

  1. Built-in back-pulse canceling diode protects your rigs keying circuit.
  2. It maximizes your talk power without distortion and splatter.
  3. Eventually, this massive inrush current will damage your amplifier.
  4. When that transmit key is down, someone somewhere can hear you.
  5. Let's assume you're using a tuner with an inductance switch, because they are the most common.

Thank God I had the privilege to serve. You now have these options. Your cold tube filament suffers abusive thermal shock. If not, loosen their Allen screws and rotate the knobs so that they point to mid scale. Even a dummy load gets out somewhere!

Make sure that you don't overdrive your amp also. This exclusive Ameritron feature lets you adjust output power on the convenient front panel display. Com reserves the right to overwrite or replace any affiliate, commercial, or monetizable links, posted by users, with our own. It saves hundreds of watts wasted as heat.

When noise peaks out using your ears and the S meter, your tuner settings should be very close for final operation. Youll be able to log some of those stations first. If the knobs are pointing to half scale with the reference markings on the knobs and front cover, consider yourself lucky. Active electronics lets you read true peak or average power in two power ranges.

Step-Start Inrush Protection When you first turn on your amplifier, a massive inrush current flows. This will prevent you from overdriving the amp. Everything working when I switched over to fm and keyed up. So re-check and re-tune as needed as you move around the band.

Still learning the rig but getting better at figuring it out if pointed in the right direction. Get instant bandswitching, no tuning, no warm-up, dating gym trainer no tubes to baby and no fuss! It connects from the accessory din plug to the relay on the amp.

No tubes, no warming up, no tuning, 757 ever. Flat mount on wall or shelf in your ham shack for best viewing angle. Ameritrons exclusive Adapt-A-Volt power transformer has a special buck-boost winding that lets you compensate for stressful high line voltage and performance robbing low line voltage. Confirm Action Are you sure you wish to do this?

Ball bearing venier reduction drives with logging scales on both the plate and load controls make tuning precise and easy. Quiet pressurized ventilation keeps your tubes safely cooled A quiet blower pressurizes the cabinet with a large volume of air flow. View Quote Not my day for cognitive ability. The key here is to make sure there's something present to protect the rig from potential voltage spikes from the amp.

How do I connect an Ameritron amp to my Icom

  • Going from watts to the full legal limit gives you less than one S-unit increase.
  • What mode are you trying to tune up in?
  • Note that the rf is actually flowing in both directions and not just toward the antenna.
  • Looking forward to getting the amp going before work gets back in the way of fun again.
