[RTTY] New Radio

[David G3YYD]

You could try a K3 next. I can say I have run a K3 (well 2 of them in fact)
since 2008 and they work nicely at 100 watts on RTTY contesting. The RX is
top of the tree in terms of performance.

The price is not bad if you don't want 2nd RX etc. You can buy what you
need. Roofing filter wise the stock 2700Hz plus the 400Hz is all you need.

I used an Icom IC-718 as a dedicated RTTY contesting radio for 1 year. It
was tough as nails on transmit at 100 watts full duty cycle, go figure! But
it wasn't good as far as IMD at 2 kc on receive.

I ran an Icom IC-746 Pro as a dedicated RTTY contesting radio for 1 year. It
had over heating problems on transmit at 100 watts full duty cycle and I had
to add an external muffin fan on back. It also wasn't that great as far as
IMD at 2 kc on receive.

I ran an Icom IC-756 Pro 3 as dedicated  RTTY contesting rig for 2 years. It
had over heating problems on transmit at 100 watts full duty cycle and I had
to add an external muffin fan on back. IMD at 2 kc on receive compared to
the other ones listed above was better.

I ran an Icom IC-7600 as a dedicated RTTY contesting rig for 2 years. It had
over heating problems on transmit at 100 watts full duty cycle and I had to
add an external muffin fan on back. But it also had over heating problems on
receive go figure! Maybe it was just this particular rig, I don't know? IMD
at 2 kc on receive compared to the IC-756 Pro 3 was better.

I have been running an Icom IC-7410 as a dedicated RTTY rig for the past 3
years. It is tough as nails on transmit at 100 watts full duty cycle and it
has no problems with over heating so have not had to add a muffin fan on
back.

IMD at 2 kc on receive is tied with the IC-7600 with the two optional
roofing filter installed. I actually use two Icom IC-7410's. Of course the
IC-7410 is missing dual watch, a pretty color screen, a visual waterfall and
real time spectrum scope. But none of those bells and whistles are missed by
me while contesting.

I'll probably try an IC-7610 when it comes out.
