RE: [Elecraft] Rework stuff
Phil, This is one aspect that I would like to see the rework eliminator guys reconsider, but since you have now added D19 and D20 and have changed C71 to 120 pF, do the next step and enter the K2 menu and set D19 to ON - then you should be able to get all bands within range. By the way, the range of voltages allowable after making these changes is between 1.0 and 7.5 volts, but make an attempt to get them all within the 1.5 to 7.0 volt range first. 73, Don W3FPR > -Original Message- > > Maybe some one can help.

Re: [Elecraft] Rework stuff
Phil, Check the "companion guide" on their web site. A menu setting also needs to be changed. (extended vfo) Bill K3UJ Maybe some one can help. I am building K-2 # 5423 with the rework eliminators. I got the unmdules and missing parts but the instructions were not good for installing missing parts. I figured it all out except the 60 meter module. I installed D-19 and 20 before testing and alignment part II. All was fine until VCO control voltage setting. The low and high freq voltages at R-30 were well within range on all bands except 40 meters where it was 7.000--5.51v 7.300--7.91v and sensitivity seemed low on 40. Then I discovered on the K-2 schematic DO NOT install D 19, 20 with out changing C-71 from 82pf to 120pf. I replaced C-71 with the 120pf that came with the rework parts and now 40 is deaf and the VCO voltage is7.93 volts at 7.000 and hardly changes up to 7.300. Are there other changes that need to be made? Maybe somebody reading this has had this problem. tnx Phil ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Rework stuff
H i; Maybe some one can help. I am building K-2 # 5423 with the rework eliminators. I got the unmdules and missing parts but the instructions were not good for installing missing parts. I figured it all out except the 60 meter module. I installed D-19 and 20 before testing and alignment part II. All was fine until VCO control voltage setting. The low and high freq voltages at R-30 were well within range on all bands except 40 meters where it was 7.000--5.51v 7.300--7.91v and sensitivity seemed low on 40. Then I discovered on the K-2 schematic DO NOT install D 19, 20 with out changing C-71 from 82pf to 120pf. I replaced C-71 with the 120pf that came with the rework parts and now 40 is deaf and the VCO voltage is7.93 volts at 7.000 and hardly changes up to 7.300. Are there other changes that need to be made? Maybe somebody reading this has had this problem. tnx Phil ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
