K2 RS-232 Command Set
Locked
 
|
Hi folks,
I want to take a stab at a homebrew remote control application for the K2. Can anyone point me at a source that describes the K2 RS-232 command set/responses/etc? I understand it's related to the Kenwood rs-232 but I still haven't had much luck tracking it down. Any help would be appreciated. 73, Steve __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

I finished the installation of the 3080 option, and everything seems okay, but my power out seems to have dropped on all bands. Not by a lot, but I'm wondering if something is amiss.
Here are the numbers, using the same 13.4v external supply before and after: Band Before 3080 After 3080 80m n/a 3.1w 40m 3.9w 2.7w 30m 4.2w 3.9w 20m 3.8w 2.8w looks like I've lost about a watt on 20 and 40. Current draw is good on all bands, about 65ma on 80 and 45 ma on the others. Is this worth worrying about? I read about the resistor mod, but that would raise output on all bands, maybe pushing 30 and 80 up above 4 watts, perhaps not a good idea. Is there an adjustment I missed for 20 and 40? Thanks, Mike N2HTT 4 band KX1 s/n 099 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Steve,
It is easier than trying to compare it with the Kenwood command set - just go to www.elecraft.com and click on 'Manuals and Downloads' - near the bottom you will find the K2/KIO2 Programmer's Reference - download that and it will tell you more than you wanted to know about the K2 KIO2 commands. 73, Don W3FPR > -----Original Message----- > > I want to take a stab at a homebrew remote control > application for the K2.

RE: KXB3080 Installed! Power a little low tho'

Mike,
While a watt or so is not worth worrying about, you may want to check your KXB3080 installation carefully, especially the new Low Pass Filter toroids. My experience with 5 KXB3080 kits so far is that the power output will be close to 4 watts on all bands with a 14 volt power supply - note that this is with the resistor change and 18 turn L3 installed. I have found that some wattmeters will read a bit low on 80 meters, but replacing the 1N5711 diodes in the KXAT1 will bring the 80 meter power out indication close to the actual power output. You will need an RF Probe or 'scope connected across a good 50 ohm dummy load (or a known accurate external wattmeter) to determine whether your KXAT1 power calibration is correct. 73, Don W3FPR > -----Original Message----- > > I finished the installation of the 3080 option, and everything > seems okay, but my power out seems to have dropped on all bands. > Not by a lot, but I'm wondering if something is amiss. > Here are the numbers, using the same 13.4v external supply before > and after: > > Band Before 3080 After 3080 > 80m n/a 3.1w > 40m 3.9w 2.7w > 30m 4.2w 3.9w > 20m 3.8w 2.8w > > looks like I've lost about a watt on 20 and 40. > > Current draw is good on all bands, about 65ma on 80 and 45 ma on > the others. > > Is this worth worrying about? > > I read about the resistor mod, but that would raise output on all > bands, maybe pushing 30 and 80 up above 4 watts, perhaps not a good idea. > > Is there an adjustment I missed for 20 and 40? > > Thanks, > Mike N2HTT > 4 band KX1 s/n 099 > _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Steve, Here is the information you may need: K2 Programmer's Command Reference - RS-232 Computer Control http://www.elecraft.com/manual/KIO2%20Pgmrs%20Ref%20rev%20E.pdf Hope this helps. 73, Bill - WA5PB -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Stephen Okolita Sent: Saturday, April 22, 2006 9:13 PM To: [hidden email] Subject: [Elecraft] K2 RS-232 Command Set Hi folks, I want to take a stab at a homebrew remote control application for the K2.
