[Icom] 706 MKIIG and switching power supply

[Bert]

I have two Alinco DM-330V switching power supplies.

I use one for my 706 and one with a Kenwood 570.

Noise and birdies all over the place with the 706.

Practically none existent with the 570.

I have swapped the power supplies with the same results.

Anyone have any thoughts or a similar experiences ?

Thanks and 73,

Bert
