Dennis, The Maxar is a low-end, economy radio that may be difficult to convert to 6m. I tried to convert some VHF high-band Maxars to 2m, and found their performance to be disappointing- even after doing all of the capacitor changes. I must assume that the low-band models may be equally problematic. If you buy your crystals from a reputable house like ICM, they will come with an appropriate compensation capacitor to provide rough temperature compensation- but it still drifts far more than a good channel element would.
You really should have the service manual on-hand before trying to modify the radio out of band. The good news is that manual 6881033E75 is still available from Motorola Parts. The bad news is that it costs about $58. My advice is to pass on the Maxar and find a low-band MaxTrac. I bought a 2-channel MaxTrac (D51MJA93A5AK) two years ago, and paid $35 for it- one of the best deals I've ever made! Other than programming it to 6m and tweaking the VCOs, it works perfectly without any modification. That may be the exception to the rule, but it just happened to work for me. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Dennis Ashworth Sent: Wednesday, January 28, 2009 8:48 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Motorola Maxar mods for 6M? I have a Motorola Maxar, plate number D31TRA2300AK I scanned through the Repeater builder site and didn't find many hits on the model. I want to put this on 6M - any experience on how difficult it would be to insert a 6M crystal set/realign? Any thoughts or referrals would be most appreciated Tnx Dennis, K7FL Battle Ground, WA
