Re: [Elecraft] DB15HD cable sopurce

[Ken Widelitz]

Hi Bob and Jim,

Jim mentioned he was looking for a 15 pin through cable. I don't know the
specs on the Y Box. Since I had just moved my radios around I needed a
longer cable to go from my K3 ACC to TopTen band decoder, I was looking for
a 15 pin straight through extension cable, M/F. I misread Jim's post and
thought he was looking for an extension cable as I was.

I had already bought three extension cables that looked like they would do
the trick, but  one after the other wasn't what I needed. The first one
that was advertised as straight through actually wasn't and the other two
both had connectors on the K3 ACC end that were molded such that they
couldn't turn and be screwed in to the K3 ACC nuts. That wasn't obvious
from the photos.

The extension cable in the link arrived today and works as I desire.

73, Ken, K6LA / VY2TT

Re: [Elecraft] Difference between a K3 and a K3S

[Tom]

I wonder if I can upgrade my K3,  (Sn # 53, yes 53),  to the HRO-500 
concentric knob? Anyone done that?


And yes, I have expressed interest to Elecraft for the synth upgrade.

We (K8AJ and myself) will be buying a K4, but when it shows up, um, she 
gets primary use of it.


I'll be allowed to use the K3 and any leftover antennas. So I had better 
make the K3 the best I can.

Re: [Elecraft] Difference between a K3 and a K3S

[Bill Frantz]

When I ordered the 100W card for my K3, the one delivered was 
the one for the K3S with the bypass relay.


As you got closer to the K3S radios, a K3 you ordered would have 
the more modern cards. Kinda of a gradual upgrade.


If you hava a late serial K3, it might be worth popping the 
cover to see what is in your radio.

Re: [Elecraft] Difference between a K3 and a K3S

[Dave Cole]

Hi,

Remember those filters are Roofing Filters, not the normal filters you 
see in a rig, and use to isolate a CW signal...


The digital filter, (you just dial the bandwidth you want from the front 
panel), in the K3 far surpasses anything I have used in the past, I get 
to very narrow bandwidths, and not a sign of ringing...

Wow.  Thanks for all the replies!

There are some options that I don't care about, like the extended receive
range.  I would like the I/O board, DVR, 100w, ATU.

Not sure about the transverter but if I find a K3 that has it, fine.  Is the
main reason for getting the transverter option is so you can use the 144
option?

I'm using the recommendation from the Elecraft website to determine the best
choice of filters - 2.8, 2.1, 400, 250 & 200.  99% of what I do is CW and
contests.

I will sell/trade my K2/100 setup to help me make a deal!

floor by a small amount (several dB) and was quite a bit better in close 
in reception near very strong signals. I think I saw no debilitating

Re: [Elecraft] Difference between a K3 and a K3S

[David Olean]

I bought a K3 SN 8858  just before the K3S was announced at Dayton. It 
had the new synthesizer. I was curious to see what the difference was 
between the two and ran a few simple tests in my alleged lab using an 
older K3 as a reference rig.  I found the new rig had a lower noise 
floor by a small amount (several dB) and was quite a bit better in close 
in reception near very strong signals. I think I saw no debilitating 
effects of a 1 milliwatt signal that was 1.00 kHz away from a very weak 
signal right near the noise floor. I was impressed!  0dBm vs -138 dBm!!

Mike,

You can look at the numbers on Sherwood Engineering's Receiver Test Data List, 
specifically the 5th, 6th and 7th items from the top, and the KX3 is just a few 
items lower.

Re: [Elecraft] Difference between a K3 and a K3S

[NJMike]

Wow.  Thanks for all the replies!

There are some options that I don't care about, like the extended receive
range.  I would like the I/O board, DVR, 100w, ATU.

Not sure about the transverter but if I find a K3 that has it, fine.  Is the
main reason for getting the transverter option is so you can use the 144
option?

I'm using the recommendation from the Elecraft website to determine the best
choice of filters - 2.8, 2.1, 400, 250 & 200.  99% of what I do is CW and
contests.

I will sell/trade my K2/100 setup to help me make a deal!

Thanks,
Mike NJ2OM

Re: [Elecraft] K2 battery options

[Don Wilhelm]

Lou,

The charging mechanism for the KBAT2 is specifically for the SLA 
battery.  It may work for the LiFePO4, but that is just a guess on my 
part based on the terminal voltage.


Secondly, you should not exceed 15 volts, so a 4 pack of Li-Ion exceeds 
that voltage.


Then there is the matter of charging a battery different than an SLA.
Use a charger that matches the battery chemistry chosen.  You could add 
a direct connection to the battery to plug in the charger.  See my 
website www.w3fpr.com for some ideas - do NOT eliminate the fuse inside 
the K2 - it is important because a battery contains a LOT of energy and 
can cause fires and spew molten metal should a short occurs.  Murphy 
says it will happen!

Don W3FPR

I have an early K3 that I fully upgraded, including the KXV3B board that has

I understand that the DSP and associated audio boards, and the RF boards also

Re: [Elecraft] Difference between a K3 and a K3S

There a LOT of differences between the K3 and the K3S.
Many are minor improvements but some are major.
Built in low noise 6M pre-amp for one. You don't have to buy the outboard
unit.
Somewhere I made a list of them all when I was considering whether to
upgrade my K3 or buy a new K3S.
After looking at all the pluses, I went with the new radio.
Also, many of the K3 options will work in the new K3S too, so I basically
bought a bare-bones K3S-100W version and swapped the filters etc.

I designed a hardware-software system to create thermal ex-core neutron energy 
spectrum signatures in operating pressurized water nuclear plants. We used 32 
bit integers as far as we could, even though the ADCs were only 12 bit, because 
speed was of the essence, and there was a lot of math going down. We used 32 v. 
16 bit integers because the math took results into that range. I have not kept 
up with speeds in hardware, but imagine that the IEEE 754 in hardware must be 
pretty fast.

Re: [Elecraft] Difference between a K3 and a K3S

[Tom Azlin W7SUA]

I agree.

My sort of early K3 ( s/n 17xx) simply has received every possible 
upgrade put including the new synth board and the new I/O board. So is 
pretty close to the K3S seems to me. If I was unlucky enough to have 
purchased the last K3 I would have simply put in all the upgrades. Both 
are worthy radios. My K3 is a field day veteran on a 4A club and did 
very well with nearby K3 stations ( we did an all Elecraft FD with a K2 
and multiple K3s. With antenna gain on 40 and 20.)

Mike,

Seriously, You don't have the new i/o board, with it's sound card built
in and USB connectivity. There are a couple other things changed on the
mother board that you can't get anyway with out buying a K3S. They
weren't showstoppers for me. There is a second preamp, more att. levels,
built it ATU will bypass, better speaker amp, Fast rx/tx switching,
extended 630 and 2200 meter bands. There might be more that I can't
remember, but the synth and i/o board are the biggest. There was a chart
on the Elecraft website but I don't know where it is now.

Hope this helps

Re: [Elecraft] Replacement Manuals

[N4ZR]

Meanwhile, the online service that printed my PDF of the manual was a 
lot less than that.  The company I used last summer was printMe.com, and 
it cost $11.99 combo bound and mailed to me..  They don't appear to have 
that service any more, but instead they use Staples, Office Depot, etc. 
to do the printing and binding remotely.

The new I/O board was also an option that was sold separately as an upgrade
to the K3, as was the KXV3B, where the pre-amp was located.  If you find a

If only we had 24 bits at RF. "Reasonable cost" for an ADC that can sample at 
120+ MHz gets you 16 bits at present.

Yes, you can download a PDF and if (like me) you want a hard copy, there
are reasonably-priced online services that will print and bind any PDF.
I did this to update my older K3 manual with all the fixes and
additions, which I have added but which weren't documented in the manual
that came with the radio.

Re: [Elecraft] Difference between a K3 and a K3S

Was the KSYN3A synthesizer ever built into the K3 as a standard item?  If so, 
beginning at what serial number?

Re: [Elecraft] Different focus

[Bill Frantz]

IEEE Binary Floating Point assumes (except in case of a very 
small, de-normalized number), that the high order bit of the 
mantissa is a one. With this assumption, it doesn't need to 
actually represent the one in memory. So, it has 8 bits of 
exponent, 1 bit of sign, and 24 bits of mantissa crammed into 32 
bits. It should be able to handle the full precision of a 24 bit 
AtoD converter.

Yes: More bits than 16, more monotonicity in the LSBs, general improvement in 
SFDR, or lower

internal noise.


Adding more ADC bits does not require more DSP horsepower. The DSP is 32 bit 
floating point.


Well, that works up to 23-bits! (FP numbers have a 23-bit mantissa)

Re: [Elecraft] Difference between a K3 and a K3S

The K3 has a bipolar HPA, the K3S is FET.  In my case the bipolar is more 
reliable and has lower TX IMD.
