Nice to see new good rigs on market.
We have plenty to choose, it is clearly bonus for all hams.

Hi Benny,
Only new Icom expected is the IC-9100 Daylight to DC box. Looks
interesting, and would most likely be compared to the Kenwood TS-2000.
The receiver is a double conversion superheterodyne. They claim +30 dBm

There is a serious misconception by some true believers that Elecraft
invented down-conversion (or at least conversion) to an i-f in the 8 to 9 MHz
range.
Nothing could be further from the truth, and I know that the folks at Elecraft
would never claim as much. I had a Henry Radio Tempo-1
I believe some of the older Kenwood's also had a low MHz IF out - 8.8 or 8.9
MHz.
I know this because I have a Kenwood SM-230 that requires an 8.9 MHz IF
input.

I had the chance to look at the FTDX5000's manual last night, as I was

I'm surprised that Yaesu still insisted on using a proprietary interface
requiring a special connector.
The FT-990/1000/2000/5000/9000 PKT input with a standard DIN 5 is
hardly proprietary. Other than the DIN 5 that has been around
for many years - the PKT jack is not functionally different
Thanks for pointing that out Joe. I should probably have used a better
word. By proprietary, I was simply meaning that it's not as common an
interface as an RS232 port, and two 3.5mm audio jacks. Almost everyone has
stereo patch cables and perhaps a straight DB9 serial cable laying around.

less

3. Made in USA (not mandatory, but it's always nice to support
I read and enjoyed the review. It looks like a very good product, and will
no doubt sell well - as it should.
For me the only advantage it would have over my K3/P3 is the integrated 200
W capability and integrated power supply with 12V power - both nice
features. But I wouldn't consider buying
I don't have the article in front of me at the moment, but I believe I read
that Yaesu was aware of the QSK relay issue and a circuit fix is available
for existing customers. All future production units will have the fix
already implemented.
