Specifications

One of the most misunderstood and mistuned modes available on the FT-101 transceivers is the AM (Amplitude
Modulation) transmitter. (Second only to the RF Speech Processor!) The FT-101 has one of the best on-air signals for AM
that you may ever find in a stock radio. It is also one of the easiest to make a mistake. The
most common mistake is
measuring AM power the same way that you measure SSB or CW signals using a watt meter. AM is very different.
The most common mistake is running too much carrier power in AM mode. The FT-101 can only deliver 30-40 watts of AM
carrier in linear service. The reason for this is that an AM signal contains a steady carrier and two sidebands that contain
your audio. The amount of RF power in this modulated AM "envelope" is actually 4-times the carrier. This means that a
modulated AM signal with a 30-watt carrier is actually transmitting 120 watts of power. This is the amount of power needed
from the power supply to transmit this signal. It is also approaching its absolute power limit. The same is true with the
matching FL-2100B amplifier. A 300-watt carrier contains 1200 watts of RF power when fully modulated. There is nothing
worse than "cooking" a FT-101 by running AM with a 100 watt carrier. The power supply, tubes, and amplifier components
cannot deliver 400 watts of power, are run continuously beyond their maximum rating, and for long periods of time. Beware
when purchasing one of these 11 meter 'cooked' radios!

Background: As a buyer or seller, you need to know the fair market value of shipping so that you can finalize the exact
cost of any deal. There should be no surprises as you hand over the box to be shipped, and no surprises when the box gets
opened. The following information will allow for accurate shipping costs, assuming you have weighed the package carefully,
for delivery anywhere in the United States or overseas.
Sizes and Weights: The sizes and weights for each piece of Yaesu equipment is listed above. None of the Yaesu
transceivers or accessories exceed the size and weight limits imposed by any of the major common carriers, such as UPS.
Shipping should be a very straightforward process, and with a little planning, your package should arrive in the same
condition as it was shipped.
Estimating Final Weight: Accept the fact that shipping will add 20%-25% to the actual weight of any unit. Yes, a 30
pound FT-101E transceiver with manual and power cords will actually weigh 38 pounds ready to ship. A two pound
YD-844 microphone will weigh 3-4 pounds if packed properly. The heaviest in the series, the FL-2100 amplifier (41 lb.) will
tip the scales at 52 pounds at the counter! Don't underestimate the weight of shipping!
Packing Considerations: Remember that you are responsible for ensuring that the equipment is packed properly and safely
for its journey. The longer the trip the better it must be packed, especially overseas. NEVER use newspaper for any of
packing material. It is not resilient to compression, it holds moisture, and will leave ink on painted and plastic surfaces.
When possible, use the original Yaesu packing box and materials. Prior to shipping any unit, remove all AC cords,
microphones, accessory plugs, and the brass spinner on the main VFO dial. Do not use tape on any plastic or painted
surface. Ensure that all covers are on tight. Put the unit in a plastic bag (as a moisture and dust barrier), and then wrap in
bubble wrap. Select a box which allows at least 2" on each side to survive a hard "knock" while in transit. Place enough fill
to cover 2" in the bottom of the box. Insert the unit and fill completely with packing to the top.
