Be sure and re-seat the Aux cable on both ends.  Then make sure both screws on both ends are fully engaged and tight to secure the connectors.  Just plugging in this type of connect is not good enough.

I actually ran an RCA cable from the K3 key out to the amp Key in. It is working perfectly since. Must be a problem with the AUX cable.

Thanks for your response. Doug from Elecraft contacted me and informed me that the heat sinks are where I was describing the heat source.  How did you know I was old enough to remember Valves. lol

I have sn4290 and it gets slightly warm on the right side but not hot.
Does it get as warm as the tube gear used to get, if you remember
that?

Re: Heat

K3s here and right side is luke warm.  If I remember there is a SSD mounted there, so it serves as a heat sink, but don’t quote me.  I’ve built two K3’s from kits and the last one I have I purchased already built.  

I’ve never experenced a heat problem with any of my K3’s

Hi Mark.
 
Sorry I misunderstood. Yes, I was talking about the internal transverter, although I’d assumed that they were both the same in operation.

Alan,

 

Are you referring to the internal 2m option for the K3? I’m talking about the external XV144. It’s manual says (on page 3 frequency range 144-146 Mhz.  It also says that the IF input range is 28 – 30 MHz. Although, interestingly, the IF input range of the XV432 is 28 – 32 MHz.

I can’t help you with other rigs, but I can tell you that the 2 metre transverter DOES cover the entire band 144-148 MHz. It’s in the spec at the top of the manual and there’s even a warning about a relay click on crossing the boundary between 146 and 147.

 

Unfortunately I can’t use the 146-148 MHz part of the band, due to living in a restricted area, but I can assure you that the K3 tunes the transverter across the entire band.

Re: KPA1500 Macro help. PF combination for FAN Speed.

Mark W2OR
 

Yes, Jim.  Thanks.  Tho I was already aware of that. 

Let's see, in the original posting and original question, am looking for a command that can be used in just PF1, that will toggle between ^FC2 and ^FC0 . . .  on the same PF button.  Hmm.


Re: KPA1500 Macro help. PF combination for FAN Speed.

Jim N7US
 

Mark,

 

The commands were as in the original email:

 

Yes, both PF1 and PF2 can be used for this purpose, PF1 set ^FC2;  and PF2 set to ^FC0.

 

I assume the screenshot from the KPA1500 Utility below won’t be conveyed to the reflector, so I’ll send you a cc directly.

 

 

But, as I said, I don’t use the PF1 and PF2 very often, as I use the KPA1500 Remote program with its slider to set the minimum fan speed (I usually leave it at #1).

Thanks for the reply and the idea, Jim.  So, if you have in fact "done that", just as outlined in my original post, I'd be most interested if you could enlighten us readers to the macro command that was used.  Thank you. / Mark

Re: Heat

 

To the right side are mounted the voltage regulators developing some heat. So hot right side is normal.

Re: 2m Transverter

Steve VE3RX
 

Some transverter vendors will provide a 50Mhz IF, giving the whole 2M band coverage. There may be a cost to adding a 50Mhz IF instead of 28Mhz....


Re: KPA1500 Macro help. PF combination for FAN Speed.

Jim N7US
 

I have done that with PF1 and PF2 but I prefer the KPA1500 remote program, which allows you to set a minimum fan speed with a slider:

 

 

Yes, this is 6M FT8, though I’d prefer to be on 6M CW, but no “fish” there.    (I’m near Chicago and am working stations in TX.)

 

You can use macros for the amplifier, radio, and K-Pod if you use VA2FSQ’s Win4K3Suite.

Hello, all. 

Looking for a Macro Command String for PF1 that would, on first pressing, turn the fan to Speed-2, and on the second pressing of PF1, would turn the fan speed to Speed-0  (zero).   Any ideas out there ?  See below.

Yes, both PF1 and PF2 can be used for this purpose, PF1 set ^FC2;  and PF2 set to ^FC0.  That's easy. But PF2 here is already occupied.   Tks for your comments.

FYI:  The K3 had a limited number of functions for which the repeated pressing of the PF button would cycle different 'on' and 'off' functions. Speakers/Phones was one of them.  But that's for the K3, quite a different beast.  //73
