KX2 <> KX3
Locked
 
|
Hi All,
I have for mobile / portable a K3 of the old vintage that I am thinking of passing on and getting either a KX2 or KX3. I dont need the 100w so either should be ok but I wonder which any of you more active outsiders would recommend. Also I notice Elecraft gear sells very quickly in the States but not too sure what the second hand market is like in the UK. Any suggestions or help gratefully received. 73 de Tony G6GLP --- This email has been checked for viruses by AVG. http://www.avg.com ______________________________________________________________ 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] |

Unless you install the new synth and DSP board, with possibly a few of the
minor mods available from Elecraft, you won't get top dollar for your K3. However, I don't think you'll have any problems selling it. Just before the K3S was launched, I paid around £1000 to a private seller for a K3, which I've since upgraded to almost K3S standard. There are a couple of UK Facebook groups for buying and selling rigs and of course there's always eBay. Another place to advertise it would be RadCom. 73, Alan.

The KX2 is smaller and lighter. The KX3 covers more bands. Both
are harder to switch between SSB and Data modes than the K3. You make the call. 73 Bill AE6JV On 10/11/17 at 7:35 AM, [hidden email] (Tony G6GLP) wrote: >I have for mobile / portable a K3 of the old vintage that I am >thinking of passing on and getting either a KX2 or KX3.

Tony,
I own both. For portable ops I'd go with the KX2 hands down. Smaller and better battery life on the internal battery. My KX2 has been to SOTA summits in Japan, Singapore, California, Texas, and Virginia, so it travels great and takes up very little room in the small camera case that you can order with it. But hey, they're both great radios so you're not going to lose either way! Have fun! 73 -Brad Butler W6BJB/JS6TQS -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Tony G6GLP Sent: Wednesday, October 11, 2017 7:35 AM To: [hidden email] Subject: [Elecraft] KX2 <> KX3 Hi All, I have for mobile / portable a K3 of the old vintage that I am thinking of passing on and getting either a KX2 or KX3.

Hi All,
Decision made now and I am going for the KX2 but now I have a question about the Batt Li-ion. The charger looks like it charges down the power lead and I am wondering how the balancing is done. Does the pack have its own balancing circuit or what. 73 de Tony G6GLP --- This email has been checked for viruses by AVG. http://www.avg.com ______________________________________________________________ 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] |

Tony,
The battery must be removed for charging. The charger and battery are from the same manufacturer and I figure they have "done it right" whether that be a balancing circuit in the battery pack or some device in the charger. 73, Don W3FPR On 10/15/2017 2:36 PM, Tony G6GLP wrote: > Hi All, > Decision made now and I am going for the KX2 but now I have a question > about the Batt Li-ion.

Hi Don,
I am sure they have done it correctly but I have a number of different charges for li-po and other type batts so was just thinking of either not getting the charger or just providing another batt as it only seems to connect via 2wire connection for powering the rig. 73 de g6glp On 15/10/2017 20:04, Don Wilhelm wrote: > Tony, > > The battery must be removed for charging. > The charger and battery are from the same manufacturer and I figure > they have "done it right" whether that be a balancing circuit in the > battery pack or some device in the charger. > > 73, > Don W3FPR > > On 10/15/2017 2:36 PM, Tony G6GLP wrote: >> Hi All, >> Decision made now and I am going for the KX2 but now I have a >> question about the Batt Li-ion.

One possibility would be to get a 3-cell battery holder, and charge the
cells independently. A charger which charges several cells simultaneously, but independently, would assure balance. Unless you use smaller cells, however, the will have to be external. 73, Scott K9MA On 10/15/2017 14:17, Tony G6GLP wrote: > Hi Don, > I am sure they have done it correctly but I have a number of different > charges for li-po and other type batts so was just thinking of either > not getting the charger or just providing another batt as it only > seems to connect via 2wire connection for powering the rig. > > 73 de g6glp > > > On 15/10/2017 20:04, Don Wilhelm wrote: >> Tony, >> >> The battery must be removed for charging. >> The charger and battery are from the same manufacturer and I figure >> they have "done it right" whether that be a balancing circuit in the >> battery pack or some device in the charger. >> >> 73, >> Don W3FPR >> >> On 10/15/2017 2:36 PM, Tony G6GLP wrote: >>> Hi All, >>> Decision made now and I am going for the KX2 but now I have a >>> question about the Batt Li-ion.

Tony,
Lithium Ion is a different chemistry than li-po. I would choose to be safe rather than sorry and buy both the battery and charger. If you are going to be operating portable over a long weekend, consider a 2nd battery. Yes, it can be powered from an external power source through the 2.1mm coaxial jack. For best results, the power supply should have a voltage of 13.8 volts or more - up to 15 volts is OK. BTW - the internal battery can plug into that jack as well. 73, Don W3FPR On 10/15/2017 3:17 PM, Tony G6GLP wrote: > Hi Don, > I am sure they have done it correctly but I have a number of different > charges for li-po and other type batts so was just thinking of either > not getting the charger or just providing another batt as it only > seems to connect via 2wire connection for powering the rig. ______________________________________________________________ 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] |

Scott,
The stock battery pack is sealed as one unit, not 3 individual cells. Perhaps you are talking about a possible alternative battery supply and not the one sold by Elecraft. 73, Don W3FPR On 10/15/2017 3:59 PM, K9MA wrote: > One possibility would be to get a 3-cell battery holder, and charge the > cells independently.

To directly answer the question, the balancing circuitry is built into the battery for the KX2. Typical for these types of enclosed batts. The balancing device fits within the depression of the cells.

Yes, I meant separate batteries, NOT the Elecraft battery. I should have made that clear.
One possibility I've considered to reduce weight is a three cell battery holder for AA Li-ion batteries, good for about 800 mAh, as I have used with the KX1. With the KX2, they would be good for about 2 hours of CW contest operation at 5W. 73, Scott K9MA ---------- Scott Ellington --- via iPad > On Oct 15, 2017, at 3:15 PM, Don Wilhelm <[hidden email]> wrote: > > Scott, > > The stock battery pack is sealed as one unit, not 3 individual cells. > Perhaps you are talking about a possible alternative battery supply and not the one sold by Elecraft. > > 73, > Don W3FPR > >> On 10/15/2017 3:59 PM, K9MA wrote: >> One possibility would be to get a 3-cell battery holder, and charge the cells independently.
