Re: [Elecraft] KDVR3 Firmware request

2008-12-12 Thread Alexandr Kobranov
Guys, it is -IMHO- all the time the same like with activation of KEY 
OUT port by hitting the Key when on CW and pure PTT mode. This 
activation of PTT and RF Out my hitting M1 is much worse.
Please, take in consideration that K3 can be part of very complex line 
where all PTT/RF OUT activity are strictly controlled and ANY unwanted 
activation can make some demage to some - not so cheap - part off it.


I hope K3 will be able (after some F/W development) to avoid ANY TX or 
"like TX" activation by hitting the Key or M1-M4 buttons or any others 
in the future. It is not about to delete today´s functionality, it is 
about to have a chance to change it. This very conservative approach 
(user selected as no everybody wants it) - if in PTT mode there is no 
other way how to activate TX (with or without RF out) then PTT itself 
- will be great I suppose...


73!

K3/10 #727

P.S.: not having DVR yet but "1 or 2 weeks to sent" :-)
so no tested here locally, sorry if misundersood reports about it...

Yes, or at least mine does, and I want it that way. It's not really
what I'd consider VOX, though - it's activated by pressing the button,
not by the audio.


What about if I have used PTT with a foot switch and keyed the K3 and 
the 8877 on two meters and the T/R relay in the amplifier has been 
switched can I tap M1, etc. and send the DVR CQ or other message?


I get strange results when I try that. I think the firmware is getting
confused. The message starts to play, then cuts out. If I try it a
few times, it starts working. If I then go back to just pressing the
button, with no PTT, it acts strange for a few attempts too.

I think there's a firmware bug, perhaps related to PTT canceling DVR
playback. I'm not sure how it's supposed to work if you press the M1
button when PTT is already asserted.


If this is true I can make this work.  Obviously I have to be sure to 
activate PTT with my foot switch before hitting M1, etc. or almost 
certainly burn up the T/R relay trying to "hot switch" 1500 watts.


If this works then I would assume even if I take my foot off the foot 
switch the DVR continues(simulates VOX).


Good question. I'd expect the TX to be a logical "AND" of the potential
assertions (PTT, VOX (from mic) and CW keys), and it should keep
transmitting while ANY of them are still on.

The other part of that is that the DVR and mic audio probably should
be mixed together in the case where both DVR and PTT are active.


I certainly need to keep my foot on the PTT switch until the DVR is 
finished to prevent burning up the T/R relay if there was a simulated 
VOX drop out.


I really think you'd be better off using the KEY OUT from the K3. Is
there some reason you can't do that?


So another question if you are in PTT and you hit M1 and it starts 
transmitting(simulates VOX) does the VOX settings such as delay in 
effect.  I have a hard time getting used to things doing VOX like 
action when you are in PTT.


Again, I don't think it's VOX - I think it's a separate software TX
assertion, but Wayne/Lyle/someone would need to confirm.


You answered my question about CW on SSB in that you can defeat it 
sending CW when in PTT.  I never have read the CW Weight item as I 
don't mess with that on CW so thanks for telling me where it is at.  
It surprised me the other day when I was in SSB with VOX off and I 
accidentally hit the CW key and tripped the protective circuit on the 
Alpha 99 as the amplifier was not set up as I was just listening 
around on different bands thinking since I was not in VOX it would not 
transmit.


Yeah, I think a case could be made for requiring VOX or PTT for CW in
SSB mode. Maybe it should be a configurable option.


It is a nice feature to be able to transmit CW when in SSB mode and 
the menu item handles the situation well.  I normally will have it so 
it can not send CW but over the years I have seen times where this 
feature would be nice.


I've used it as a quick way to tune-up when band-switching in an SSB
contest (with a straight-key positioned right next to the amp) :)

I'm still having strange problems with it dropping out in mid-message,
but it doesn't seem to be related to pauses in the audio. Infact
sometimes the audio drops out and it transmits silence for the remainder
of the message duration. Firmware bugs that need to be ironed out, I'm
sure.


Thanks for your help.  There are not a lot of them out yet and the

I have another question on the KDVR3. If I am using PTT rather than VOX 
can I play a DVR message by tapping for example M1.  Let me explain 
more.  A long term problem with VHF contesting and using DVR on two 
meters and above is hot switching the amplifier T/R relay at high power, 
ie 8877 on two meters.  By and large people use PTT and even then in 
some cases a sequencer to be sure the amplifier T/R relay has to be 
closed or at least gets a head start at two meters and up.  If you use 
DVR on VOX you soon burn up an amplifier T/R relay at Two meters and up 
unless it is an expensive vaccum T/R and I have seen them go!


With the KDVR3 I am wondering when using the K3 with a XVERTER if one 
can key it and the amplifier it is driving with PTT and then play the 
KDVR3 message tapping the M1, etc. key.


I am assuming if the VOX is not on the KDVR3 will not key up the radio 
if you accidently hit M1, etc.


Pressing M1 *does* key the radio even if you're in PTT mode, and it
should - I don't want to have to separately assert PTT (or use VOX) to
transmit a recorded audio message.

I don't drive an amplifier myself, but I understand that there's a
configurable delay between they KEY OUT of the K3 and actual transmit.
I expect it should apply to DVR-initiated TX as well as PTT . Wouldn't
that be sufficient?


However I am wondering since in USB or 
LSB you can send CW even though the radio has the VOX turned off. Put 
another way you can not transmit with the mic until you engage PTT but 
if you hit the key it still works jsut like VOX.  Maybe there is a 
setting where that can be defeated but if so I have missed it?


Are you asking about the CW key or the M1 button? The CW key will only
be active in SSB mode if you have turned on "SSB +CW" in CONFIG:CW WGHT
(manual page 53). Whether or not that should key the radio without VOX
or PTT is an interesting question, but I'm not sure if it's the one
you're asking! :)

Re: [Elecraft] KDVR3 Firmware request

2008-12-11 Thread Ed Gray W0SD
Dave, your points are very well taken! I agree that most of these 
matters need to be dealt with in the contest/operating software. 
However I still think that a firmware choice to prevent all but the most 
intentional erasure of a message or recording with the KDVR3 would be a 
good thing.  It is like a computer file, once it is gone it is gone 
forever unless there is a backup.  If you spend the time to record a 
good DVR on the KDVR3 I think having a choice so as to not lose it very 
easily would add a lot as a reason to have a KDVR3. I think the same 
would hold true of a nice on the air recording you made with the KDVR3. 
 I don't think this is not as serious as you should be able to play it 
on the "line out" and save it on the computer and make backups and have 
it for the rest of your life or send it to someone else.  Of course if 
you don't back it up you could lose it.


Another good use for the KDVR3 would be on a one or two person 
DX-pedition, maybe larger.  They can have the KDVR3 installed in the K3 
and do their messages.  With this firmware change they would not have to 
be concerned about losing them.  Often one or more of the team members 
are not that familiar with the radio and could accidentally erase a 
message.  Generally you just have a laptop on a DX-pedition so using the 
KDVR3 would be a great step forward IMHO.  My experience from being on 
several DX-peditions is that a laptop lacks when it comes to using a 
contesting program with one or no com ports, etc.


Personally I can not get very enthused about plugging my microphone into 
a computer and then running wires here and there.  IMHO it just adds to 
the chance of cable problems, etc. but that is personal preference. 
This is even more true on a DX-Pedition, forget one cable and you are in 
major trouble in the places I have been!!!


So we agree a lot of this should be handled by contesting software but I 
think the KDVR3 installed in a K3 should be made as useful as reasonable 
possible through the firmware or why sell it?  I realize different K3 
users have different likes for a KDVR3 but I think they would be 
interested in protecting their effort in creating a good DVR message so 
it was not easily erased just like your computer operating system gives 
you a second chance before you delete something.


I think the beauty of the K3 firmware in that within reason things can 
be done to enhance the use of the K3 with the KDVR3. It is not unusual 
for me to spend 1 hour getting a "near perfect" DVR message.  I would 
like to have a way to protect that "near perfect" DVR.  However I do 
agree with Dave and never intended in trying to make it a SO2R DVR radio 
even with two K3's.  This is beyond what needs to be done in the K3 
firmware and is not fair to the broad spectrum of K3 users most of which 
have no interest on SO2R. For that matter I don't do SO2R but some of 
the people who operate here do.


There is a downside to getting contesting software to do what you want 
it to do and that is you have to convince the authors to do it for the 
K3.  Sometimes that is not as easy to do as it might seem.

that problem.


You connect your mic to MONO MIC IN of the sound card, and STEREO LINE 
OUT from the sound card to the radios' LINE IN, with left channel going 
to the left radio, and right channel going to the right radio. Mic is 
muted when messages are playing. Messages can be re-recorded on the fly. 
Different messages can be stored in the voice of the different 
operators. Different messages can be used for S&P vs. CQ mode. With this 
setup, you don't need to connect a mic directly to the K3.


Just some thoughts to keep the issue in perspective.

First a little back ground as Wayne probably has not read the line-In 
+ Mic discussion.


When one uses the computer for a DVR for contesting an easy way to do 
it is to take advantage of the Line Input but given one also wants to 
use the mic for operating then the "MIC" is hot during the playing of 
the DVR.  For SO2R there are added issues of switching the DVR from 
the computer and the mic between the two radios.  Lyle KK7P pointed 
out that an external program could easily set the active Tx audio path 
from MIC to LINE IN, send the audio, then switch the Tx audio path 
back to MIC. The problem is to get your program author to make those 
changes for the K3 but definitely an option!


I am thinking the KDVR3 is a better way to go to cure the "hot" mic 
and associated sound card problems.  It also should get rid of the 
"black box" for SO2R DVR with two radios
