As you rightly point out, everyone has an opinion. I think that the convention 
varies from community to community.
The Outlook and Exchange clan seems to like top-posting. The old USENET / Unix 
folks see to prefer bottom posting.

and for fun : https://www.google.com/search?q=top+posting+considered+harmful

Best advice here is to get guidance from the moderator and failing that - the 
community consensus. In either case, consistency is better than alternative - 
which I admit - I have done here. 

Since this is a meta discussion, I will refrain from responding further to 
limit list traffic. Private comments are welcome.

There is a certain amount of humor intended here.

Re: [Elecraft] KDSP2 option's DSP firmware is open source

2014-08-26 Thread Alan Hawrylyshen
Actually Wayne (and others); 

Like others - I discovered this a few years back and made a private fork on 
github in October 2011.
I took some time to really dig in an concluded that I didn’t have the right 
tools to do even basic experimentation.
I applaud that you’ve made it public and I’d encourage Elecraft to continue in 
this spirit where it isn’t commercially to your disadvantage. I would also 
encourage using something like github as a great way to share the code that 
permits maximum utility for people trying to work with the code. This form of 
version control is radically different (and in most ways superior) to 
everything that has come before it.

[ IF you aren’t using it in-house - it might be worth investigating if it is 
time to migrate from whatever you are using, to git.] I’ve helped a few major 
software development organisations move to git and the end results can be quite 
excellent. I certainly wouldn’t consider any other form of code control these 
days. ]

Wayne ; Best wishes and I’m always willing to chat about this technology and 
how to use it within organisations.

Cheers,
Alan

 That was rather well hidden; it's the first I heard about it.
 
 However I'm not surprised that there were no takers.  Assembly languages 
 coding for DSPs is well outside the main open source community (although 
 there probably is a sub-community for it).  Most people would be into C for 
 desktops or assembly for PICs.
 
 The other problem, at least in the UK, is that sourcing DSP chips in small 
 quantities is likely to be difficult, and I suspect the programmers 
 (hardware) are expensive, especially compared with those for low volume 
 programming of the PIC.
 
 In practice I've not found a strong enough need to justify adding audio

[Elecraft] K3 + P3 Combo Pelican / Hard Case

2013-11-29 Thread Alan Hawrylyshen
I have looked at the archives a little bit, but I haven't quite stumbled on
a short and sweet paragraph or two about this.

Has anyone selected and used a Pelican case to protect and transport a
K3/100 + P3 combo. If so, what case did you choose?

I've been looking at the 15xx (1550) and possibly the iM2500 cases; but
they are quite 'tight' dimensionally. I'm interested in any experiences
people have with:

1) Pelican Cases for a K3/100+P3 combo (I mention /100 because of the fans
hanging back), and/or;
2) Experience with a similar but potentially less expensive option.

I'd like to pack my radio up for the trip to G-land and select a case that
would allow me to take the radio on a DXpedition at some point -- so an
option is to expand the case size to include the power supply, etc.

More than anything - I'm interested in opinions around how much space is
needed to protect the radio, etc.

Thanks
Alan

Re: [Elecraft] creating an audio file to email

2013-11-24 Thread Alan Hawrylyshen
Todd;
It is worth noting that there are a few parts to solving this problem. Audacity 
is a great software package, but it is only needed for the encoding of the file 
format problem. You can get the recording into your computer without anything 
else. There is a sound recorder utility included in Windows and on other 
platforms here are similar utilities. You can break this problem down into 
three parts:

1 - Connecting your K3 to your PC so the sound can be captured. (Requires 
cables discussed at length in the mailing list archives. Jim, K9YC has some 
sound and simple advice (no need for fancy sound interfaces if you are careful).
2 - Playing the recording without transmitting (TX TEST mode is useful here) 
and recording it on the PC in any format you can.
3 - Converting to a nice compressed format for email.

You can do 2 and 3 together if you have the right software, but if you want to 
get it out of the rig 'now' you can defer step 3 until you have an audio 
transcoder like Audacity available to you.

Just save the sample as a WAV file and test playing it back on the computer. 
You might find that this file is appropriate to email if you use an 8kHz sample 
rate…

If you want to compress it for email, then you will need to use a transcoder 
(such as the functions built into Audacity, QuickTime or other examples)…

There is no good reason to record the DVR output at anything higher than 8kHz 
sample rate, but 16kHz will be an appropriate amount of overkill. 44.1 and 48 
kHz is just a waste of space.

Good luck,
Alan

Re: [Elecraft] Semi-OT: Traveling by air with KX3 Buddistick

2013-10-09 Thread Alan Hawrylyshen
Nicklas;

I've carried on my KX3 with NiMH batteries many, many times. Only once did they 
ask what it was - swab it - and carry on. I travel with either an Elecraft BL-2 
and some random wire or a G5RVjr -- never looked at twice in dozens of flights. 
I have no data on a buddistick - apologies.

I will note that some international locations get VERY upset over HTs - they 
likely ignore the KX3 because they do not identify it as a 'radio'. I had to 
negotiate for over 30 minutes to get my VX-8R permitted on the plane in Malaga, 
ES -- as the security people were adamant that no 'unlicensed, operational, 
walkie-talkies' were permitted. ... 

The HF gear has never raised any concern beyond the usual electronic device 
scrutiny level. For reference, I fly around 100K miles per year and take an HT 
and KX3 almost every time. I haven't had a lot of time to operate on trips, but 
that's a separate problem.

Best,
Alan

 It seems like it SHOULD be okay, unless they mistake segments of the

[Elecraft] [P3] Use with K3.

2013-05-04 Thread Alan Hawrylyshen
All;

I have a question about whether or not this is normal behavior and if it is, an 
explanation for the differences I'm perceiving will help me feel less 
inadequate about my knowledge here.


After following the guidelines in the K3 and P3 manuals, I've calibrated the 
S-Meter on the K3 and the level calibration on the P3 (using an XG3 as the 
signal source). I notice that regardless of what I seem to do, the S meter 
reads 1-2 S units higher on the K3 than on the P3 'peak envelope' display. Is 
something amiss, am I misinterpreting things, or is there something I should 
check for?

I have SMTR MD nor. SMTR PK Off. (but have tried with on).

The K3 S-meter displays no bars with antenna disconnected and S-2 at 1uV and 
S-9 at 50uV as expected. The factory default settings for the calibration 
values more or less 'just worked'. 
The transfer gain in the P3 is set to -10bBm IIRC.

Comments or thoughts anyone?

Thanks

Highly recommended.

I heartily agree. The Art of Electronics is worth it's weight in gold. 
Comprehensive and surprisingly accessible for the technical depth.

Re: [Elecraft] Elecraft T1 Tuner

 All,
 
 I am to the point of contemplating tuners to go with my FT-817 and 
 (probably) 20m half-wave OCF dipole antenna.  Has anyone used the 
 Elecraft T1 QRP tuner?  Can anyone speak intelligently to the (de)merits 
 of the device?  It gets really great reviews on eHam, but I tend to be 
 overly cautious of eHam reviews.  I'm interested in the opinions of 
 trusted sources before I plunk down the green for the kit.

I've used the T1 with my 817 for over a year. It is reliable, easy to use and 
solid. I am selling my 817 and I want to include the T1 in the sale so it is an 
attractive offering to the new purchaser, but I have pangs of doubt over 
parting with the T1

Even though I really do not need it anymore, it was so useful that I'm sure at 
some point in the future I will regret selling it. 
I also had the FT817-to-T1 cable but because it uses the same port as the CAT 
(or was it the data port) control, I rarely attached it at my home QTH. In the 
field, it was awesome.
There is a fairly trivial cable you can built to accommodate both the CAT and 
T1 cable - I just never got around to building it.

As close to having a built-in tuner as you could want. The size of the T1 is 
simply amazing - and as an aside, I have yet to change the battery.

 2. If your computer boasts over 4 gig of RAM, you must throttle it back to no 
 more than 4 GB. This is done via the msconfig utility. Hit the Windows 
 'Start' icon, type msconfig and hit enter. This brings up a system 
 configuration screen. Select the 'boot' tab and then 'Advanced options...' 
 Now, in the screen that comes up, enter 4095 as the maximum memory and hit 
 'OK'. When your computer is rebooted, it will have 4 GB of RAM at its 
 disposal.

 I gather that no one has found a small laptop with stereo input ( mike

 No dongles.


The 11 MacBook Air has stereo in. :-) And it is NICE and small.
You could - if slightly crazy - install Windows on it. :-) Or just run DSPradio 
/ GNUradio.
