That is within the transceiver range of the GRC9, so they should be able to communicate.<br /><br />"Repair" might be too strong a word. I have tracked down a couple problems with mine related to magnetic whiskers in the tuning plates as well as a bad vibrator. I still have a frequency "jump" occurring during transmit that I haven't tracked down. <br />I've spent more time fixing the DY-88 than working on the radio itself. Taking apart and reassembling the Dynamotor was not fun.AA4OOhttps://www.blogger.com/profile/08437750216586991500noreply@blogger.comtag:blogger.com,1999:blog-1146246558798303856.post-85179056835909884592023-01-25T19:56:10.901-05:002023-01-25T19:56:10.901-05:00I can't find the video but the readings return...I can't find the video but the readings returned to normal past 36" and were greatly reduced beyond 24"AA4OOhttps://www.blogger.com/profile/08437750216586991500noreply@blogger.comtag:blogger.com,1999:blog-1146246558798303856.post-19049526021284683482023-01-15T01:59:49.175-05:002023-01-15T01:59:49.175-05:00I have a GRC-9 and love it - a super cool rig.
