Does the 6600M have relay or pin diode filter switches?

David Salomon

I may be using my new 6600M for MIL-ALE-141 via PC-ALE or MARS-ALE (or both).  When scanning, the software can do up to 10 frequency switches per second (multiple bands).  A radio with relay switching for the filters will die quickly under those conditions (at least the relays are likely to die an untimely death).  A radio that uses pin diode switching should fare much better.

So, which is it for the 6600M?

This is a fallacy that the radio will die quicker with relay switching.  The relays are rated for a very high number of actuations.  I did the math a while back and if the radio ran 7x24x365 with a band change every 10 seconds, you will not hit the rated spec for something like 10 years. 

BTW, it is a reed relay, not a pin diode.

Thanks for the elmering!

So the 6600M is using reed relays vs mechanical relays, correct?

WOW I’m glad to hear that they are reed relays they are super reliable and fast.

That makes two of us.

Is the same relay used in the 6400?

Yes

In QSK mode, it uses a reed relay.
