Hi Jeff -

I've had two of the ICE 419's for many years and they seemed to perform well. Recently they both developed problems with the relays not making good contact when switching bands and being sensitive to mechanical "shock" (pounding on the box...).

I spoke with WX0B at Array Solutions, which took over ICE a while ago, and Jay told me that they don't work on the 419's any more. I have replaced one 419 with a Bandpasser II and am very happy with it; it interfaces well with my K3. I still use the better 419 on one radio, but occasionally have to send a "dit" after switching bands before I get good contact from the relay.

73 - John, W4AU

Looking for feedback on multi-band bandpass filters to use for SO2R.

The two I'm considering are the DuneStar 600 and the Array Solutions BandPasser 
II. I've used the Dunestar at our contest station in Bonaire and they seem to 
work OK. We have occasionally had to send one back for repair with one of the 
band positions not working anymore. Guess we maybe blew it by having it on the 
wrong band when transmitting.

What are you serious SO2R guys using?
