Last year we purchased a VSWR meter and it was used until mid-July after which it was returned to me. After that date there is no record of a member loan but the device is not in the Club equipment box either. I may have loaned it out but lost the records of the member it is on loan to. If anybody has the meter can they please reply to this post. Many thanks, John Wighton -------- John Wighton Europa XS trigear G-IPOD Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501621#501621 ________________________________ Message 4 _____________________________________ Time: 03:18:19 PM PST US Subject: Europa-List: Re: Cruise speed data for Monowheel with 912ULS From: "Griffo" Paul/Duncan, Not sure of your message? You both seem to be saying, the fuel you are commenting on, is at least 95+ RON. This is the lowest grade that ROTAX recommends, so should be OK. -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501623#501623 ________________________________ Message 5 _____________________________________ Time: 09:31:02 PM PST US Subject: Europa-List: Re: Europa Classic Pre Purchase Advice From: "Griffo" Thanks for all that.
