IC-7000 VFO Stability

Is the IC-7000 stable enough for FT8 use on 50, 144, and 432 MHz?

Randy,
Interesting question. Look forward to hearing your testing scheme and results. Will you look at frequency drift? What tolerance is acceptable? What will you use as instrumentation to measure frequency? Good Luck Kurt KD6LZV |

I can verify that the 7000 works FT8 on 50 really well. I made over 600 qsos on 50 in the last two years. Very stable radio. 73 de NJ2f, Jeff On Sep 25, 2019, at 2:10 PM, Randy <hamradio@...> wrote:

When you say frequency stability, do
you mean the ability to transmit on an exact frequency? If that is
the case, FT8 should work very well even if your VFO is a little
bit off frequency. As long as you are in the band-pass of the
receiver all should work fine. What is more important is that you
have a very clean signal and not over driven.

Works great
I have hundreds of contacts, DXCC (not all confirmed yet), and WAS, on the 7000 I like having the temp indicator. I did do a fan mod to better couple the sensor to the heatsink. |

Hi,
Mine works very well in all bands except 432 MHz where there is a signinifcant drift in frequency when TX starts. However, I managed some DX on FT8...but several times I could not decode the signals because of the freq drift when RX cools down after TX period :-) There is a quick solution to this....to put some thermal protection over the TCXO which otherwise is placed directly in the blow of the ventilator.

I've been using an IC-7000 for 2 years on FT modes.It is my backup rig.and works perfectly.
