K3 DC Output
Locked
 
|
According to the Manual the K3¹s DC output socket is limited to 0.5 amps,
which I understand means it can power a P3 alone but not both a P3 and a PR6-10, nor a P3 with the VGA accessory. I looked through the on-line manual for the mod kit this morning - it looks like major surgery. Did Elecraft incorporate the mod in K3¹s shipped after the mod came out in 2012? My K3 is S/N 7562. Tnx, Ted, KN1CBR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Ted,
Yes, K3s manufactured after the mod came out do have the 1 amp output rating starting with SN 6588. The Owner's Manual itself has not been updated, but Errata Rev D10-5 dated June 9, 2014 states the places where the manual should be manually updated. 73, Don W3FPR On 12/22/2014 11:55 AM, Dauer, Edward wrote: > According to the Manual the K3¹s DC output socket is limited to 0.5 amps, > which I understand means it can power a P3 alone but not both a P3 and a > PR6-10, nor a P3 with the VGA accessory.

Even if you had an older K3, it's very minor surgery. It's been some
time since I modified my K3 (serial no. 00007) but I think it involved the replacement of two components.

Actually, the hardest part of installing that change is removing the
KPA3. Once that is accomplished, the rest of the mod is easy - as Vic said, it is a matter of changing two components. 73, Don W3FPR On 12/22/2014 3:40 PM, Vic Rosenthal 4X6GP/K2VCO wrote: > Even if you had an older K3, it's very minor surgery.

A $5 pair of long-reach surgical forceps or hemostats will do the job without unnecessary disturbance to major organs. Remove only the rear fan panel, and then it's easy to reach down behind the KPA3 using the hemostats to remove RFC48 and F2. Lightly clip the hemostats onto the component and then unsolder from underneath. After clearing the holes of solder, use the hemostats again to insert each new component from above. Easy! Hemostats are readily available as craft tools on eBay for only a few $/£/EUR, and the 6-inch straight pattern is probably the first one to buy. 73 from Ian GM3SEK ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

The mod kit has a label for the higher current capacity that is used to cover the original one on the K3. I'm guessing new K3s are labeled correctly with the higher available current.
