I have the same experience that Philippe has.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
After many tries, on Dummy load first then with distant Ham friends, conclusion was to re-installed MCU 4.14. Instead of giving the same dynamic with the MH2 microphone, with my Amp on, using 12w drive, using Mic=2 COMP=20, pronouncing the number 6 slowly, I have seen immediately the difference. For me, using a Amp w/GU84B tetrode, 12w drive on ssb give 500~600w on normal voice operation. With MCU 4.17 it gave only 300~400w and the power increase with difficulty on a single whistle to 500w. and when I pushed to maxi drive 65~70w I was unable to achieve the normal 64dBm+ of the Amp with normal voice. Normal cw tune procedure seems not affected and I can achieve the maxi as normal. The most important: It has been reported to me during the test on the air, some alteration of the modulation, like a RFI ground phenomena on the microphone or like a under voltage problem during transmitting. I've checked all connections from A to Z and no problem founded. re-load 4.17, installed it 2 times, with no changes. When re-installing the MCU 4.14 everything is back to normal with the very clear voice provided by the K3.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
Phillippe, You state the mic gain setting and the compression, but for the K3, the most important setting is to obtain 5 to 7 bars on the ALC meter with the compression turned to zero. If that is not done as the first step, then the K3 cannot properly control its power output. After setting the mic gain level for those 5 to 7 bars, then increase the compression to whatever you want. You may want to recheck to be sure your mic gain is set correctly (even though an SSB bug apparently came along with 4.17. BTW, thank you for trying the beta firmware - it is good to give Elecraft feedback on problems like this one. While I am not saying this is your problem, we need frequent reminders of this initial requirement because many instructions for amplifiers and for digital interface boxes (use 4 to 5 bars for digital) will lead you to believe that you should control power output with the mic gain setting. While that is true for many transceivers, it is not good advice for the K3. From the many posts on the reflector, there was a problem for SSB power output (bug) that happened in MCU 4.17, and Wayne has said he is working on it. 73, Don W3FPR On 11/5/2010 1:45 PM, Philippe Trottet wrote: After many tries, on Dummy load first then with distant Ham friends, conclusion was to re-installed MCU 4.14.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
Nate et all, I stand corrected. Looks like K3 #2730 also has this issue. I didn't notice at first, but then noticed it last night. Performing a TX calibration didn't really fix it completely, although it did help. Glad to know that the boys at Aptos are working on it. 73 de James K2QI On Thu, Nov 4, 2010 at 2:02 PM, k2qi@gmail.com wrote: Nate, have you tried reloading the firmware? I'd give that a shot first.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
Successfully downloaded MCU4.17 and began experimenting with APV. It took awhile to find a weak CW signal - 20m band must be in good shape. I did find one that was pretty spotty reception in 2.8-KHz bw; a bit better with 400-Hz. Then is turned on the APV. I could see a definite improvement once I got familiar with how to use it; signal went S=0 to S=2. That is a nice enhancement in the firmware. I will be doing primarily weak-signal CW with my K3 on 144-MHz and 1296-MHz eme. The 400-Hz filter takes some getting use to compared with 400-Hz DSP bw on my FT-847 (i.e. there is NO comparison). The 8-pole K3 xtal filter just chops off everything outside the narrow band. Background noise drops significantly, too. I may want to do my eme search in 2.8, then narrow bw once I find a signal to copy. Fortunately, Ihave sw can detect a carrier way below audio threshold (down to SNR= - 28 dB in a 2.8-KHz band). I tested my SSB Tx levels using TUNE and the mic (on 20m) and they indicate normal RF output so not seeing any issue on my K3/10 (16w max output) (#4030). I did play with CONFIG: PB CTRL 0.05 or 0.01; the 0.01 seemed to work with APV nicer. --- Sidenote: My new 1296/28 transverter was shipped on Wed. Just confirmed that I will be receiving a prototype dual-RX transverter for 144/28 MHz. Steve at Downeast Microwwave is using me as beta-tester for this new model. I will run it with my dual-polarity 2m antenna array to capture polarity-angle information using Linrad sw. This will utilize the dual-Rx in my K3. I guess you could say this will make my eme station a polarity diversity receiver.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
Additional testing shows that when I set my power down to 5 Watts and then back up to 100 Watts results in a max peak output of 50 Watts on SSB on both an external and the K3's Wattmeter. Setting the mode to CW results in 100 Watts output and reverting back to SSB I can get about 75 Watts peak on both meters. 73, de Nate -- The optimist proclaims that we live in the best of all possible worlds.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
I went through the CONFIG menus to see what might have changed while in SSB. I found DUAL PB had APF on. I was unable to turn it off while in SSB, so went back to CW mode turned the APF off (nor) and returned to SSB and all was normal. Full output. I have confirmed you can only turn APF on/off while in CW mode. It would then seem that APF should be turned off automatically when in any mode other than CW.

Power fine here with 4.17. Get full 100W PEP out on both CW and SSB and the drive power that I normally use for my amp is as accurate as it always was. Checked two K3s with an Alpha 4510, an LP-100A and an Array Solutions PowerMaster. I don't see anything different at all regarding power calibration (what it should be putting out versus what it atually is) or PEP out on two K3s and checked with three different meters.

Well, rolling back is worth a shot. I've never had problems reverting to previous versions. Plus, look at it this way - what variables have changed?

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
I am seeing the same reduction in SSB output power. I installed 4.17 Beta last night. It appears that the reduced power only occurs when I have APF activated. I have twice restored SSB power by doing the following: 1). Changing mode back to CW, 2). Going to Dual PB in Config menu and turning APF off, 3). exiting Config menu, 4). changing mode back to SSB. Power is restored back to a full 100 watts. With APF set to on, SSB power is reduced to about 70 watts. I confirmed this on 17M by repeating the process twice, and I then tried 20 M SSB and the power was back to 70 watts (after I had turned APF back on.) Is this a problem with the beta release? I saw Wayne's suggestion to do a TX gain calibration, but it seems strange that I would only need to do this after installing Beta 4.17. APF works great, but I need to resolve this SSB power issue.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
Now I seem to have a real problem. I did a TX Gain calibration using the K3 Utility for both 5 and 50 watts. I worked perfectly and tx gain appeared to be right on all bands. I then did some testing into a dummy load with RTTY. I noticed that power would start out at 25 watts and it would take several transmissions to get it up to 70 to 100 watts. So I decided to do a wattmeter calibration. I had selected WMTR LP and was attempting to do the 5.0 W calibration into a dummy load. But I could not get the output power to change much and after several tries I got a high current reading. Now I can get audio only out of the left side of headphones and when I attempt to reselect the WTMR parameter it is no longer there. The selection in Config skips from VFO OFS to XVn ON. I assume I have blown something out. However, I am considering reverting back to MCU version 4.14. Any other suggestions? Thanks in advance.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
OK, my SSB output was low too. I'm on phone so rarely, were it not for the reflector, I'd probably never have checked and when I did find out, the thread would have already died. I did the TX Gain calibration as Wayne suggested, all seems to be well on all bands. Apparently, the DL in my MFJ tuner isn't all that 50 ohms-ish on 6m, but the trusty Heath Cantenna is. The APF feature is really quite amazing. I have to miss SS CW, family stuff, but I'm anxious to try it out for real. It already got me 9U0A, he was whisper weak, maybe S[minus]1, I got 9A and wondered why the pileup on a 9A? APF in, he sounded S5.

Re: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
Same thing to me, I was noticed it when put my Amp w/GU84B on, need 20w+ to obtain 500w in ssb instead of my normal 16w. MH2 Mic dynamics was also affected and obliged to increase the Mic gain consequently. When back to NOR Dual PB features it comes back almost to normal power but seems a bit lack of dynamic. When download back the 4.14, everything returns to normal. I have download again the 4.17 and same problem occurs but let it like this the time a solution will be available on line. Anyway the APF is really impressive to extract the weak signal and really enjoyed it. It is also a must to catch the beacons qrg's. Bst 73s Philippe A65BI Dave Perry N4QS n...@comcast.net 05-11-2010 4:34 I am seeing the same reduction in SSB output power. I installed 4.17 Beta last night. It appears that the reduced power only occurs when I have APF activated. I have twice restored SSB power by doing the following: 1). Changing mode back to CW, 2). Going to Dual PB in Config menu and turning APF off, 3). exiting Config menu, 4). changing mode back to SSB. Power is restored back to a full 100 watts. With APF set to on, SSB power is reduced to about 70 watts. I confirmed this on 17M by repeating the process twice, and I then tried 20 M SSB and the power was back to 70 watts (after I had turned APF back on.) Is this a problem with the beta release? I saw Wayne's suggestion to do a TX gain calibration, but it seems strange that I would only need to do this after installing Beta 4.17. APF works great, but I need to resolve this SSB power issue. I may try RTTY next to see what happens in that mode.

The APF works wonderfully, with only a hint of ringing to my ears. Really nice addition to the K3. At least some of you aren't seeing this. :-) James Rogers suggested turning the Mic gain to 0 and then back up and he was getting good output. After I did that, I could only get about 25 Watts peak on both meters. I switched to CW mode, transmitted a short carrier which showed 100 Watts on both meters (power control set to 100). Switching back to SSB both meters showed about 70 Watts. I have since bumped TXG VCE up to the max, 3.0 dB and am getting about 90 Watts peak on each meter (I say four in a normal voice to get the K3's meter to stabilize for a bit). I had previously had TXG VCE set to 1.0 dB. I'm not sure that rolling back to the last stable firmware would solve this or be fraught with other issues. Generally, roll-backs don't work all that well in other devices. 73, de Nate -- The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true.

We're working on the SSB problem. 73, Wayne N6KR On Nov 4, 2010, at 9:49 PM, Philippe Trottet wrote: Same thing to me, I was noticed it when put my Amp w/GU84B on, need 20w+ to obtain 500w in ssb instead of my normal 16w... __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
