QMX SSB on 4m?


 

A question for Hans:
?
Can the 5351 clock generator operate at 70MHz and be phase modulated fast enough to generate SSB??
?

Hello Tony
?
Can the 5351 clock generator operate at 70MHz and be phase modulated fast enough to generate SSB??

I see no reason why not, though I have not tested beyond 6m.?

Note also that the maximum update rate of the '5351 clock generator, when using 1MHz I2C bus, is around 16,000 times per second. This is not dependent on the operating frequency of the '5351. So there is no reason why it would be different on 70 MHz. And since 16,000 updates is plenty more than required for SSB modulation, it all should work.

Thanks Hans. It seems I am going to have to modify a couple of filters in either my QMX or QMX+ to become an SSB walkie-talkie on 6 and 4m ;-)?
