IC-7000 VFO Stability


Randy
 

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

Try it out let us know the results.

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

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.

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.

Yes, I have done FT modes on 6m including Meteor Scatter contacts. de W4WNT

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. See article on web:

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