K3 #1025 Build
Locked
 
|
K3 ser # 1025, ordered 27 Dec arrived here in Texas
Tuesday, June 10. I have built it, but when I try to calibrate the VCO I get Err VCO E00005. I have emailed support, but I am not sure if I will get an answer today. Anybody seen that error and know what it is?

The build went fine except for mounting the speaker. I think the
supplied fiber and toothed lock washers are too small in diameter for the width of the speaker mounting slots. It's pretty difficult to keep them from slipping through the slots, and then the screws go crooked.. I finally gave up and just used larger fiber washers. I also updated the firmware, no problem. Used a straight serial connection to the PC. But I'm wondering, would it be okay to plug in the serial cable while the K3 and PC are powered up? Here's an assembly hint... Use a magnetized screwdriver. It is much, much more convenient! (The only screws that aren't magnetic are the display window screws.) 73, Drew AF2Z _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I plug and unplug serial cables into my PC and K3 all the time without
worrying about powering down either the PC or the K3. If equipment tended to be sensitive and were damaged by this action it would be common knowledge, and vendors of this sort of equipment would be have to deal with many customer support issues. Successful vendors would implement a solution that isn't bothered by these (reasonable) customer actions. I've not heard that this is a problem.

The risk with RS232C is that the grounds on the too devices may differ and the equalisation current might, initially flow through a signal connection. RS232C is specified to tolerate all sorts of short circuits within its voltage range, so, if you have good ground bonding between the devices, you should be OK. Note that the AUXBus, that is on the same connector on some Elecraft rigs is not designed to be resillient. > > If equipment tended to be sensitive and were damaged by this action it would > be common knowledge, and vendors of this sort of equipment would be have to Nonetheless, RS232C is not designed for hot plugging. Equipment, like USB, designed for hot plugging has different length pins on the connectors, so that ground always makes first, and any power feed second. > deal with many customer support issues. Successful vendors would implement > a solution that isn't bothered by these (reasonable) customer actions. > > I've not heard that this is a problem. Most people have good ground bonding. I remember a case were an RS232C interface was destroyed because the trainee doing the cable hadn't connected the ground on the power distribution strip. Current leakage from the power supplies put the system ground for one piece of equipment at about half mains voltage, albeit at a high enough impedance that it only caused a tingle. Only with the serial cables engaged was it actually grounded, and inserting the cable risked doing the initial grounding through a signal lead. -- David Woolley "The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio" List Guidelines <http://www.elecraft.com/elecraft_list_guidelines.htm> _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I'm curious for those of you who use a Pelican case to carry around your
K2 what model you're using. There are several to choose from and was curious if there's an accepted model that fits the K2 the best. I'm looking at the 1450. 73 Matt W5LL _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Matt -
Consider also the Samsonite L25 soft-side case. This is a small version of a laptop case, and it fits the K2 perfectly. There is room for the K2, a Kenwood MC-43 microphone, a Palm-Paddle, a small laptop 12V power supply to use as a battery charger, the K2 instruction booklet, power cables, a folding headset, some basic antenna materials, and a few other bits. It has lots of zipper pouches to accommodate loose stuff. It also has a pair of Velcro straps inside the main case that fit snugly over the main K2 to keep it in place. Not bad for about $36 on Amazon.com. I have used one of these cases for some time now. No damage to the K2 or any of it's accessories, ever. Another advantage - it is about the size of a woman's purse (and it has a carry strap), and so far I have successfully convinced airline types that it should fit under the same rules that allow women to carry a handbag and not have it charged against my baggage or carry-on allowance. This is one time where "non-discrimination" rules work in my favor! <grin> - Jim, KL7CC Matt Patterson wrote: > I'm curious for those of you who use a Pelican case to carry around your > K2 what model you're using.

Jim,
Thanks for the info! That case sounds exactly like what I'm looking for. I'm looking for something that will allow me to take my K2 along on trips and things like that. 73 Matt W5LL Jim Wiley wrote: > Matt - > > > Consider also the Samsonite L25 soft-side case.
