Lou,
Well, "it depends". There are at least three ways the L7 bandswich was locked out from 10 meters; I assume you found the way to undo yours. For the L7s I've serviced, I found two different results with no consistent explanation for the differences. In one case, you do the mod by adding the two 68 pf caps, etc. and then retune the input coil per the instructions. In the other case, adding the 68 pf caps is not necessary, and the input coil doesn't always need to be adjusted. Both procedures seem to work, depending... 73, Evan, K9SQG -----Original Message----- From: Gudguyham <[email protected]> To: drakelist <[email protected]> Sent: Sun, Jul 1, 2012 12:01 am Subject: [Drakelist] 10 meters for the Drake L7 Hello everyone, new to the list. I'd like to know if anyone has or knows where to get an authorized bulletin from Drake outlining the procedure for enabling 10 meters on the L7 amplifier. I've seen a "blurb" about it on the Internet but nothing that seems to be Drake authorized. Although I have done the modification as shown in the blurb I am not liking the input swr results I am getting on 15 and 10 meters now. On 160-20m my amp has a dead flat input swr, but not on 15 and 10. I have questions. If no bulletins had been issued and anyone has done this mod with greater success than I, please let me know. Thanks, 73 Lou W1QJ _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist
