Re: K3 AF knob..

The same is here. It is the crack in the knob, I can see it. You can try to
tighten up the screw a bit but not too much not to finaly break the knob.
If it is not completely loose you still can find the end stop while turning
very gently and slowly. The best way surely is to get the knob replaced :)

Re: K3 AF knob..

Linas and all,

I don't know if the policy is still in place, but several years ago,
Eric stated that defective knobs would be replaced at no cost. Contact
Elecraft support.

I just contacted them this week for a broken AF knob and they said they
were sending a couple at no cost.

Re: K3 AF knob..

In reply to this post by Michael Eberle

Mike,

Yep I contacted Elecraft Parts too and they are sending me a new knob at
no cost.

Don,
I did take the knob off and test the pot and it is fine, so the knob is
definitely the problem and I'm getting it fixed via an excellent
Elecraft support policy from a few years ago. I'm guessing, but I'll
bet the other manufacturers won't do that.

Thanks Elecraft.

Re: K3 AF knob..

In reply to this post by Elecraft mailing list

Well, of the big 5, we know the policy of one of them. That's
how I got replacement knobs a year or so ago.

(I see the big DXpeditions using Elecraft and sometimes Flex
gear. I don't see them using the others very often. Perhaps I'm
missing something.)

Re: K3 AF knob..

The big DXpeditions are using Elecraft gear because they can use several
on the same band without interference from one to the other - the low
transmit phase noise of the Elecraft gear allows that to happen along
with the superior receive performance.

With ARRL Field Day coming up, that factor may be important to many
Field Day operations. The ability to operate voice, data modes and CW
on the same band is possible with Elecraft gear.

Convince your FD club to use all Elecraft gear for that reason.

Re: K3 AF knob..

The West Valley Amateur Radio Association, operating using the
call K6EI, has known the value of all modes on a band at the
same time for years. We are all Elecraft for that reason.

I realize that Field Day is not a contest, but if you look at
the results you can see how our solar powered, QRP operation scores.

Field Day rig experience

Along the line (lightly discussed under "K3- AF Knob") of what rigs are
used for dxpeditions and Field Day...... How do the new technology
ICOMs (7300 and 7610) do under the "several rigs on the same band"
conditions? The size, weight, and cost factor is inviting for the 7300 -
BUT!!! Is it up to the job? Close to up to the job? Or, better left home
during these events?

Kindly, no flames and let's answer here on the forum - so all can learn.

Thanks, Bill W2BLC K-Line

Hi Bill,

Hopefully you’ll get some responses to this question from those with direct experience. But looking at it theoretically: both the 7300 and 7610 are direct-sampling radios with about 25-30 dB less blocking dynamic range than the K3 or K3S. On Field Day this could have a definite impact when using multiple transmitters on the same band, or even on different bands, depending on antenna spacing and power level used.

Dynamic range of all of these radios is quantified in the receiver performance table at www.sherweng.com, specifically the fifth column (“100 kHz Blocking”).

Re: Field Day rig experience

Hi Wayne,

Few K3 owners are aware that the K3 has built in transmit/receiver
bandpass filters for each band. That and very low phase noise and
exceptional receiver dynamic range are why the K3 is such a superb
Field Day transceiver.

At the W3AO Field Day we use four K3 transceivers on 20 meters:
CW, SSB, Digital and GOTA. N one of the 20 meter operators will be
aware of the other three transceivers u nless one of the other transceivers
accidentally lands on the same frequency.

Is there any published data about the performance of the built in
bandpass filters?

tks

Re: Field Day rig experience

In reply to this post by wayne burdick

When the 7300 first came out, I took mine to FD for a test, with high
hopes. Proximity of antennas was close, on the order of 40
(tribander)-200' (double double extended Zepp on 40M) separation, power
output limited to 100 watts. There was a lack of trees to make more
space between antennas without exceeding the 1500' limitation (besides,
the snacks were there).

The 7300 crumpled badly, operation on other bands 'desensed' (for lack
of an accurate word) the 7300 effectively making it deaf in some cases.
It didn't matter what band the other stations were operating on, the
7300 was affected.

No band filters were employed, it was a brutal test as a 'worst case
scenario'. The 7300 failed.

The Pro-III the group normally uses, displayed no issues. No one wanted
to dis/re-assemble their Elecraft stations from home but I'm sure they'd
hold up very well or better under the same test. It wasn't a QRP event,
so the KX2/3 was not deployed.

However it's limitations, the 7300 does exactly what I intend it to be,
a cheap light weight radio with 100 watts out that I can take into the
field, use in the RV or the home shack (since I can control other
transmitters). It isn't an 'unworthy' radio, if you don't subject it to
high RF fields. Eventually, I'll have a second K3 just for the RV but
for now the 7300 will suffice.

There will be two 7610 on site this year, but I won't be there to
witness their use. The Pro-III will be there in case the 7610 doesn't
hold up.

Re: Field Day rig experience

In reply to this post by wayne burdick

I think another major concern for closely positioned rigs would be
transmitted phase noise, and of course that doesn't show up in the
Sherwood charts. Jim's tests
(http://audiosystemsgroup.com/TXNoise.pdf) show some large differences
between various rigs, although the 7300 and 7610 are not specifically
included (the 7600 is, however). The K3/S are much cleaner rigs.

How do the new technology ICOMs (7300 and 7610) do under the "several rigs on the same band" conditions? The size, weight, and cost factor is inviting for the 7300 - BUT!!! Is it up to the job? Close to up to the job? Or, better left home during these events?

But looking at it theoretically: both the 7300 and 7610 are direct-sampling radios with about 25-30 dB less blocking dynamic range than the K3 or K3S. On Field Day this could have a definite impact when using multiple transmitters on the same band, or even on different bands, depending on antenna spacing and power level used.

Yes, it does!

We have used the parking lot of Sky View HS, Soldotna, AK for several
years. HS was shutdown about five years ago and located in hills
south of the *small* city of 7500. Club has TS450's and run two
stations 80-10m, 100w under KL7AN.

I usually join them to help setup at 9am with 10am start time. This
year I will have my KX3 and KXPA100 installed in my truck, as we head
out on the road with out 5th wheel trailer after FD weekend heading
for Ohio (5000miles). Only have 80m and 20m hamsticks for HF and use
a half-wave base-loaded 2m whip for 6m. I might turn on the KX3 to
checkout close operation at the FD site.

Details of the mobile setup: http://www.kl7uw.com/Mobile.htm

Last year I was running my K3s digital, and I could see the CW operators
and the voice operators on the P3, but never heard them. At one point one
of the CW ops was only 10 KHz away and not interfering with PSK31.

Will be repeating the operation this year, with a 7A station, there will be
lots of other signals from the other radios that are a mix of Y-I-K... I'm
bringing some external bandpass filters for those other stations to use to
protect them from each other.

Look for W7TA at Washoe Lake State Park between Reno and Carson City!

Take the K3 , leave the IC-7610 at home. It’s to darn heavy to lug around. (19 lbs )

All I've ever seen from Rob is RX phase noise. Can you provide a link to
TX phase noise? The TX phase noise data I've published came from ARRL Labs.
