Re: [Elecraft] KDVR3 Firmware request
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! Lexa, OK1DST 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...

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 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! :) ~Iain / N6ML ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] KDVR3 Firmware request
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. Ed W0SD Dave Hachadorian wrote: Before getting too wrapped up in so2r/contesting dvr/mic switching within the K3, keep in mind that Writelog, and N1MM, and probably other Windows-based contesting software, already have elegant solutions to 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. Dave Hachadorian, K6LL Yuma, AZ - Original Message - From: "Ed Gray W0SD" To: Sent: Thursday, December 11, 2008 5:49 PM Subject: [Elecraft] KDVR3 Firmware request 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
