Re: [Elecraft] The 1500 watt amp

[David Gilbert]

Compared to a 500 watt amplifier, 1500 watts represents almost 5 db.  If 
you don't know what 5 db can do when trying to make weak signal contacts 
you haven't done much of it.  I'm not saying that Elecraft should come 
out with a 1500 watt amp, but amps are NOT just about being loud and 
busting pileups.  They have nothing to do with the front end of 
receivers and everything to do with fighting noise of one sort or another.

I'm pretty happy with my three Ten Tec Titans, first built in the early 
80s. Designed by K4XU. All bought used for a combined cost of less than 
$4,000. Two are in my SO2R setup, the third is a spare (T/R relays fail, 
not a good thing in the middle of a contest). I did some repairs to two 
of the three right after I bought them, total cost about $250. Not 
automatic anything, but they WORK, and they're clean. And I've been 
using them for 11 years now.

Re: [Elecraft] KAT500 cycling

[Steve Ward]

When my KAT500 started acting strange I opened it up.  There are two 
thick, green insulated wires that cross each other on the PCB, and the 
top one had sagged down and got close enough to the bottom one that it 
had arced through the insulation.  I'm guessing I had a less than 
optimal match!  Anyway after consulting support, I gently separated the 
two lines and put a double layer of electrical tape between to hopefully 
prevent recurrence.

[Elecraft] connector pin changes on final amp?

Around what serial number did the change from the nickel type pins to the gold

with overheating causing trouble with the connectors.

Re: [Elecraft] Was there a 1500w amp from Elecraft in our past?

[Jim Miller]

IMO the 1K5 amp market is a bit of a mess. I own a KPA500 and continue to
consider purchasing a legal limit amp. I'm not impressed by the offerings.

Most of amps that I've seen seem to be offered by unstable suppliers with
unstable supply chains. I'm not eager to plop down serious cash for
something that is likely to be an orphan before the warrantee is up. Plus
some of the "legal limit" offerings are pretty dirty when run full out.

I'd like the feature set of the KPA500 and legal limit and from a supplier
that has some legs. I'd like an Elecraft legal limit amp.

[Elecraft] The 1500 watt amp

[Rick Braun]

I was heartened to see Wayne’s response to this rumor.  It seems inceivable 
that Elecraft would offer such a product, much less one designed by someone 
else.   Big amps are about being loud, busting pileups,  .  When receivers were 
less sensitive and sophisticated, e.g. digital filters, digital noise 
reduction, etc., you needed power to get in the front ends of DX receivers.  We 
don’t need that power anymore except to contest, i.e. blow out the ops with 
less power.  To me this don’t seem like the Elecraft ethic.  They aren’t QRP 
snobs, and they seem to value skill, intelligence, and cunning, rather than 
brute power.   Whole big amp thing struck me as odd.

Re: [Elecraft] KX2 DSP vs bhi DSP

[Don Wilhelm]

Bret,

Actually you are comparing apples and oranges.
Any "in-line" DSP is an audio DSP processor, and it can only do 
filtering and noise reduction functions at audio frequencies.


The KX2, being an SDR radio, does everything with DSP - modulation, 
demodulation, all filtering as well as some pre-processing for the audio 
stages is done mathematically.
What we used to think of as the modulator, detector, IF filters, AGC, 
etc. in analog radios does not exist in the KX2/KX3.


Instead, the incoming RF signal is sent to a mixer which converts that 
signal to 8kHz (or baseband in the case of the KX3 without the IF shift 
active).
The resulting 8kHz signal is digitized by an analog to digital converter 
(ADC).
That digital output is mathematically massaged to produce the kind of 
demodulation and filtering that you have requested from the KX2 knobs 
and buttons.  Once that math result is obtained, it is sent to a digital 
to analog converter (DAC) as an audio signal which is then amplified to 
headphone or speaker volume.


So bottom line, while the audio DSP units (such as the BHI unit you 
mentioned) can 'massage' the audio, the KX2 does that massaging at what 
would be the equivalent of the IF in an analog radio, so the result is 
that the signal is processed much earlier in the receive chain before 
distortion products can be present by the distortion inherent in each IF 
and detector stage.

KX2, but I'm on the early learning curve end still. The KX2 is mighty sweet!

Are you using VOX to trigger transmit?  If so you might try different VOX GAIN

[Elecraft] KX2 DSP vs bhi DSP

[MaverickNH]

For those who have been with a Elecraft KX2 longer than I (1st day), just
wondering how you might compare the KX2 DSP to a bhi Compact-in-Line DSP. I
have one for use with other rigs lacking DSP. I'll get to trying it with my
KX2, but I'm on the early learning curve end still. The KX2 is mighty sweet!

I leave the KAT500 on 24/7, several years of perfect operation.

Today I sent the usual 15 watts tune carrier on 75 meters the tuner started
cycling

all lights on and off. Turned the tune carrier off but the tuner continued
to cycle.

Tuner will only turn off by removing power. Plug power back in it starts

Re: [Elecraft] Is there a 1500w amp from Elecraft in our future??

[Scott Manthe]

Yes, from 2006. Two versions of the amp were on display at Dayton, the 
KPA800 and KPA1500. Both were working prototypes and both were putting 
out power, the KPA1500 at 1800+ watts continuously into a dummy load, if 
I recall properly. Both were things of beauty and planted the Elecraft 
seed in my brain that eventually resulted in my having a complete 
K-line, minus the KAT500.

Re: [Elecraft] KX3 / FLDIGI Problem

[James Bennett]

Kevin, Kevin, Jack, & Dirk -

Thanks for all your helpful suggestions! And the winner is: Kevin Turned off 
the “PTT via Hamlib command” and that cured the problem.

Very much appreciated. Now the rig and FLDIGI are MUCH easier to operate!

Re: [Elecraft] KX3 / FLDIGI Problem

[Kevin - K4VD]

​I'm only guessing here. fldigi has at least two methods of setting PTT on
rigs. One uses RigCat (​CAT command for PTT) and the other uses Hardware
PTT.  I don't know much about Hamlib, flrig or the other tabs.

Is it possible PTT is being set by more than one fldigi method and they are
conflicting?

3. I would set the temp calibration back to where it was before shipping it

Especially since it appears that is the only change you made before the loss

[Elecraft] KX3 / FLDIGI Problem

[James Bennett]

I have a KX3 and am running FLDIGI 3.22.01 on my Raspberry Pi 3. Everything 
works… except for one annoying thing and I’m trying to find out if this is an 
FLDIGI issue or something I need to tweak on the KX3.

When I fire off a macro such as a CQ message, the rig goes into transmit as it 
should, sends the text in the macro as it should, but never returns to receive: 
the red TX light on the KX3 stays on, although the RF output ceases. I have to 
manually “tickle” the KX3 XMIT button to get the radio into receive mode. Here 
is a sample macro text I’ve been using to get this resolved:

Testing testing de w6jhb w6jhb k

Seems pretty darn basic, but in my case, basic isn’t getting the job done. 
Anyone else with a KX3 and FLDIGI know what I need to do to get this working 
w/o having to reach up there and press that XMIT button to get back to receive 
mode?

Thanks, Jim / W6JHB

Re: [Elecraft] [ KX2] KXBT2 Charger

[Bob N3MNT]

One of the main failure modes of Li-Ion batteries is trying to charge a
defective battery ( puffed pack).  When Li-Ion batteries begin to fail one
or more cells develop a high internal resistance and heat up during
charging.  The 2hr warning is likely driven by the danger of trying to
charge a bad pack more than the a time limit  for a good pack.  For packs
with built in management/balancing circuitry ( no access to individual
cells) it is difficult to see a  bad cell.  If you are concerned, there are
fireproof pouches to put the battery in during charging.  You can get them
from most major RC model sites.

Re: [Elecraft] [ KX2] KXBT2 Charger

[John]

All,

What specific chemistry are these batteries? Li-ion? LiPo? LiFePO4?

The three different types of lithium-based battery all have different ways
of 'looking after' them (I'm a heavy user of Lithium-based batteries, for
airsoft, portable radio and r/c...

I suspect the reason for the note about 'specified charging time' is based
on the chargers being designed to charge at a certain rate (usually measured
in 'C'... for 'capacity')... Presumably if it recommends a 2 hour charge,
the provided charger charges at 0.5C (half the capacity per hour).

If you stick the batteries on a 'proper' hobbyist's charger, you'll have a
variable maximum charging rate, so you could in theory cut it down and leave
it running longer... In fact some chemistries actually prefer to be charged
at anything as low as 0.1C!

If someone can fill in the blanks on battery types (and ideally the capacity
too!) that'd be fantastic.

As for the steel pan on the concrete patio... That's a great idea provided
it a) isn't going to rain and b) there aren't any bugs or creatures that
will nibble through your cabling. The conventional method of charging safely
indoors is to drop the batteries into a LiPo charging bag (available fairly
cheaply from all good r/c stores and hobbyist websites) which is designed to
contain any fire or explosion caused by improper overcharging of the
batteries. For what it's worth... LiPo and LiFePO4 batteries also need to be
balanced (and as such are sold with a 'balance connector' on a fly lead as
well as the main 'power output' connector. This allows all good chargers to
individually float a cell or pull a bit from another cell to keep all of
them in balance.

73, and a firm left handshake.

Subject: Re: [Elecraft] [ KX2] KXBT2 Charger

I put a battery in a steel pan out on the concrete patio and charged
overnight - the LED went Red to Green overnight and the battery was still
cool in the morning, so all went well.

The timer sounds like a good solution for indoor safe charging, but I'll
still do so in a pan on a patio block, just in case...  My son got a little
battery-powered remote control race car many years ago, and the battery
scorched the Formica counter top when it overheated during charging.  So
yeah, those lithiums can be nasty without proper circuitry and care.

[Elecraft] Let me build your Elecraft kit

[Alan Price]

Let me build a K2, or other Elecraft kit for you.  My prices are reasonable and 
you have a new radio with the options you want.

[Elecraft] KAT500 cycling

[Jack Satterfield]

I leave the KAT500 on 24/7, several years of perfect operation.

Today I sent the usual 15 watts tune carrier on 75 meters the tuner started
cycling

all lights on and off. Turned the tune carrier off but the tuner continued
to cycle.

Tuner will only turn off by removing power. Plug power back in it starts
cycling.

 

Sounds like a trip to Elecraft but thought I would ask here to see if there
is anything I 

can do.

 

Thanks,

Jack

Re: [Elecraft] KX3 2M External amp -- go linear!

[Edward R Cole]

Joel and all:

The 80w amplifier I build is the Klitzing amp described, below.

I purchase the unpopulated pc board from Jim and order all other 
components.  I install them in  Hammond enclosure with same heat sink 
Jim recommends, plus a 120mm square fan controlled by a 
thermistor-based ckt.  I also add a bar meter which indicates 
relative output.  I also use the ALC kit from Jim to sample RF power 
for the meter.


It runs with 8amp quiescent current at near class-A operation so very 
linear in output.  No preamp is included but the TR relay allows 
bypass in OFF so you do not need to disconnect the amp if not 
needed.  I agree with Joel that there are better preamps than 
typically embedded in most ham VHF amps.


I handle PayPal sales for the popular WA2ODO preamps (6m-13cm).

snipped-
I convinced Jim to design and build an amplifier that would make my K3
competitive with the typical 100 W HF-VHF transceivers. With my great
receiver and 10 W transmitter, I was hearing people and they weren't hearing
me. By staying at the 100 W level, I could use the same power supply that my
K3 used for HF. I have been using the amplifier for years and been very
happy with it. It is very linear up to 80 W PEP out on SSB, but happy to do
CW and FM at 100 W. See the article at:

May 2013 -- QST (p. 30)
Build a Linear 2 Meter 80 W All Mode Amplifier


Jim offers PC boards, unpopulated, as well as largely complete, for
reasonable prices via his web page at w6pql.com. This amplifier is the size
of a brick, probably costs less and is a much better product, in my view. I
recommend it without reservation.
