[TenTec] OT: 7300 buy back program

[rick@dj0ip.de]

In plain English Paul, it overloads MUCH too easily.

To prevent that, you have to use a lot of attenuation; here in Europe even
more than the radio has built in.
Then it does not overload but you can no longer hear the really weak
stations.

In most day to day operation, this is not a problem.
In contests it is.  In its present state, it is not a serious contest radio.

Icom has replied to this point in writing that it is an entry level radio,
not a high end radio.

On the bright side, contrary to many of the other Japanese radios shipping
today (i.e. 7600 and ALL Yasues), it has a clean transmitter.

Icom could fix this radio and potentially make it a great entry level radio
but they will probably leave it like that so that users wanting more must
pay more for the next higher radio.  "That" was indeed my opinion; the bit
on performance is fact.

oversold.

contest superstations because the serious bandpass filtering they would need
with any radio acts as an RX preselector, limiting the bandwidth of the
spectrum that can overload the A/D. But that won't help in EU or AS, where
broadcasters are in the passband of any practical filter on 40M, and there
are some high power broadcasters close enough to  20M to make it a problem
there too.
