What is the Speaker slider on the computer set to? Open the playback controls - normally set it to about 75%. The "meter" in the computer soundcard display will not tell you the whole story. Go to the Playback Controls to see the slider (Windows - Mac or Linux may be different). Make sure there is nothing plugged into LINE IN (it overrides the Codec line in). You may want to insert a plug into the LINE IN jack and quickly remove it just to make certain the contacts in the jack close properly. You must set the MIC menu entry to LINE. Set the audio level correctly (you can do that in TX TEST or connected to a dummy load so you do not transmit RF). Tell your software application to "transmit", then adjust the "MIC" gain (actually LINE if you have set the menu correctly) until you have 4 bars solid with the 5th bar flashing. If you cannot achieve that audio level by manipulating to Speaker slider on the computer and the MIC Gain on the K3S, something is awry - contact K3support for additional assistance. 73, Don W3FPR On 1/10/2017 5:16 PM, Dan wrote: > Did RU this past weekend and could not get KIO3B to XMIT-Receive is fine using MMTTY and N1MM.

On my Mac I need to go to System Preferences -> Sound and raise the output volume all the way. Make sure your application is addressing the correct USB device. (Don't ask how I know.) Input from the radio should work but might be low in volume.

I've been using the original SDRplay for a few months now and like the 2mhz spectrum display using my K3's IF out and Win4K3suite. Win4K3 (http://va2fsq.com/ ) has added support for the new release SDRPlay RSP2 and likely will be doing additional enhancements to take advantage of the SDRPlay RSP2 expanded device features. It is really nice in that you can have 2mhz of spectrum in the panadapter display in Win4K3 Suite. That said, CWSkimmer does not yet support the SDRplay, but there are some doing some work arounds with virtual audio cables (VAC). So, using a T connector, I also use the IF Out with my LP-Pan2 and Steinberg UR22 soundcard with CWSkimmer. The noise floor of the SDRPlay is really good and with adjustments, I am able to see very weak signals coming out of the K3 IF. 73 Doug NA1DX -- Doug Ellmore, Sr. [hidden email] ------------------------------ Message: 10 Date: Wed, 11 Jan 2017 09:30:57 +0000 (UTC) From: Johnny Siu <[hidden email]> To: Elecraft Reflector <[hidden email]> Subject: [Elecraft] OT: a short presentation to a group of primary school children about radio Message-ID: <[hidden email]> Content-Type: text/plain; charset=UTF-8 Hello Elecrafters, It is off-topic and please press delete if you don't want to read.

I'm strictly single op and no SO2R here so a single feedline to my remote antenna relay. I bought the ACOM 1500 because I felt I needed additional power at times. It is serving that need nicely. I'm slowly getting more accustomed to the operation of a manual tune amplifier after a few years of automated operation of the Electraft line. But the KPA/KAT combo is nice for instant-on and quiet idling. I usually leave my rig on all day if I'm in the house to grab the quick DX spot. At the first spot of the day of course I need to wait 3 minutes plus tuning time before getting in the pileup. I find that 3+ minutes torture. The ACOM 1500 fan is also a bit annoying. So I've decided to put the KPA/KAT back in service in the following way. Since I have a KANT3a in my K3S I will connect the KPA/KAT to ANT1 and the ACOM 1500 to ANT2. Selection of the ANT line from the K3S will therefore exclusively provide RF to one or the other. Thanks to the internal preamp of the K3S the DIGOUT1 line is freed up to provide a signal to switch the single feedline to the antenna farm between the KPA/KAT and ACOM 1500 outputs. I haven't yet selected a legal limit A/B relay but there appear to be several available. A separate relay also driven by DIGOUT1 will switch the KEY line between the amps as well. The KPA/KAT will connect via the AUX bus as usual to provide the former automation including setting KPA per-band power levels. I'll need to put the KPA in Standby to go "barefoot" and I already have the barefoot level set to an appropriate value for the ACOM 1500. The normal drive power to the KPA is also within the range of power I already use to tune the ACOM so no problems there if I forget to put the KPA in Standby. Since DIGOUT1 is per-band and per-antenna the appropriate setting will be made for each. Of course DIGOUT1 being open collector it will need to be pulled up and appropriate buffering added to ensure safe operation of the relay coils. So with two button presses I can switch between the two amps and the two ANT connections eliminates the input switching relay and wiring. Of course if a KPA1500/KAT1500 makes a debut all of this will be replaced in a heartbeat!!! Comments or suggestions welcomed! 73 jim ab3cv ------------------------------ Message: 13 Date: Wed, 11 Jan 2017 09:45:11 -0700 (MST) From: KV5J <[hidden email]> To: [hidden email] Subject: Re: [Elecraft] Tandem operation of KPA and ACOM 1500 Message-ID: <[hidden email]> Content-Type: text/plain; charset=us-ascii The KANT3a was a great add-on for those that don't want or need the internal tuner.

I have a K3 running 5.53 firmware, and a recently acquired KAT500. They are connected as in Figure 2 of the KAT500 manual, using the KPAK3AUX cable with the key line interrupter, and a separate key line to activate my AL-80A amplifier. Everything seems to work "just as per" with the exception of the frequency tracking function on receive. This was running at one time; I did a tune every time the K3 crossed a frequency boundary, and it seemed to track thereafter. Now it won't track - no relay noise from one end of the band to the other. It seems to remember specific settings, and will re-tune on transmit, but does not re-tune on VFO movement. (No split freq, either.) There is no KAT3 in the K3, so CONFIG:KAT3 indicates "not inSt", but tap 1 toggles getween KAT500N and KAT500Y, and was left in the latter position. This is no big deal, but it would be handy if the KAT500 would return on receive to the last settings for that frequency, rather than wait for a transmit pulse. Besides, it is supposed to do just that! Any thoughts?

The problem was indeed a cable - it had fallen out completely! The rig is in a tough place to get at the back, and I never noticed. The "interrupter" can only be fastened with a wrench, and I had not done that, with the results noted. Now I have found the wrench in my tool box, and I think it will stay in place! Harry, You are right about the requirement to pause - now I can see that, with the rest of the problems solved. I guess you cannot expect information transfer through thin air!

I use a Six Pak driven by a pair of ACC-driven band decoders for antenna switching between the two amps because it's there already, used for SO2R antenna switching when I'm physically at the station. That would be overkill for you - as you say, you just need a SPDT RF relay like the ancient Dow-Key's we used to use for T-R switching in the 60's. You could even buy a Six Pak replacement part open frame relay from WX0B and mount it in a mini-box with some SO-239s, very inexpensive. If I were you, I'd use a simple SPST switch instead of programming the many combinations of DIGOUT1. I run Key Out from the K3 to the Alpha 87A and key the KPA500 through the ACC cable. If I neglect to put the KPA in STBY when using the Alpha, it keys in parallel but has no drive. No extra relay, no problem. You could also key both amps concurrently with the K3 Key Out line and a Y-splitter.

Message-ID: <[hidden email]> Content-Type: text/plain; charset=utf-8; format=flowed Mike, I recently did some investigation of my repair records, and discovered that a K2 serial number of 69xx dates back to 2011 or 2012. Never fear, that serial number is fully up to date with all mods that are available for the K2. It may have MCU 2.04P while the newest is 2.04r, but the only difference between those two firmware releases is that 2.04r locks the sidetone source at U8-4. MCU 2.04P allows the sidetone source to be switched between U6-25 and U8-4 in support of very old K2s. The number of support calls and emails saying "I have lost my sidetone" prompted Elecraft to make that change. So if you have MCU 2.04P and lose your sidetone, just check the setting of the sidetone source - it is easy to change, go to the STL menu and edit the parameter - tap the DISPLAY button to toggle the sidetone source. You could also update the firmware to 2.04r (E610002 - FWK2MCU) 73, Don W3FPR On 1/11/2017 8:10 PM, [hidden email] wrote: > Anyone have a K2 close to serial 6900 that can tell me mo/yr purchased?
