Re: [Elecraft] KPA 500: No Output
Dave - Looking at your very nice website and the "Radio-end station setup," I'm wondering why you are using an external antenna switch? In my experience, especially for remote operation, you'll generally have a much more fool-proof installation using the KAT500's internal antenna switch. The way you're doing it, the KAT has no way to know which antenna it is supposed to be matching - and thereby could lead to many problems - including damage to the finals. 73 Lyn, WØLEN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of dave ingebright Sent: Tuesday, December 13, 2022 9:47 AM To: elecraft@mailman.qth.net Subject: [Elecraft] KPA 500: No Output Hello-- I have a 3 yr old KPA500 that has just exhibited it's first problem. No amplification! I am remote controlling it via the remote client over the internet from 2000 miles away. Nothing has changed in the remote shack and no wiring has been disturbed. There is no output from the KPA on any band. I can see the 72 Volt B+, and the temp of the heatsink, and I can control the fan speed, so I have control of the unit. The client shows the exciter power through the amp and the SWR. There are no alarms and I have hit alarm reset and had the power plug pulled and reset. I'd guess the PTT line is somehow open but... asking if anyone has had a similar problem. tnx de dave WB7ELY My KPA500 page: https://www.valhallatreefarm.com/WB7ELY/kpa500/kpa500.htm __ 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 Message delivered to l...@lnainc.com __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] KX3/PX3 vs FT-710
Greg, I think it is unreasonable to compare radios that come with two completely different price points (not to mention delivery dates). The KX3 fully tricked out is like, what, 3x the cost? Don't get me wrong, I absolutely prefer the fully loaded KX3 in this comparison otherwise. Dealing with Yaesu after the purchase is a lot different than dealing with Elecraft, plus the support community here is second to none. Trying to get help on Yeasu's various reflectors is pretty painful. Nothing like this group.

[Elecraft] KPA1500 front panel locked
Helping a friend connect his KPA1500 to a K3. The AUXBUS is working, following the radio etc. like normal. However, as soon as that cable is plugged into the KPA, it’s front panel buttons all cease to function. Remote control via USB or ethernet work fine. The AUXBUS cable is a proper one, not a VGA cable. I’ve never seen this before and can’t find any reference to a locked front panel.

Re: [Elecraft] KPA500 App
Thanks, Jack. Yeah, I realized what I did after Walter sent the link. I went here (https://elecraft.com/pages/kpa1500-kpa500-kat500-remote-software) the first time and only saw the Windows files. I thought I had seen them for macOS previously but, for the life of me, I couldn’t find them again. Thanks again.

Wayne, You and your crew at Elecraft are champions.

See release notes below, or on our K4 software page, or view them in the updater on the K4 itself. (For your convenience, the list below shows all significant changes since production release 31.) Software development is continuing in multiple areas, including remote control. 73, Wayne N6KR * * * R32 (PRODUCTION) == December 13, 2022 - SSB/ESSB TRANSMIT AUDIO LOW-FREQUENCY RESPONSE IMPROVED: The nominal SSB transmit audio low-frequency rolloff can now be moved down from about 200 Hz to 100 Hz. (Amplitude at 100 Hz then increases by nearly 20 dB.) This selection is made using the new "TX Audio LF Cutoff, SSB" menu entry. IMPORTANT NOTES: (1) The 100 Hz selection is *always* applied in ESSB mode. (2) In addition to using this new SSB setting, you can control the transmit passband in all modes using TX EQ. (3) If you use USB or LSB for audio DATA modes such as PACTOR that require fast turnaround times, you should not use the 100 Hz SSB setting, because it slows turnaround by about 20 milliseconds. (The high-performance digital filter required to obtain a lower passband has additional "taps," resulting in greater delay.) - KPA1500 / KPA500 LOSS OF BUTTON PRESSES: In previous releases, some amp front panel button presses could be missed by the K4 due to the concurrent handling of other band-change activity. - RADIO LOCKUP DURING VFO MOVEMENT AT ~5600 KHZ: One operator discovered a radio lockup when moving the VFO in the vicinity of 5600-5620 kHz. This was due to incorrect lookup of ATU LC segment data, which has now been corrected. - TERMINATION OF DVR MESSAGES no longer causes occasional loss of mic audio. - REPEATER OFFSETS are now correctly applied to VFO B when in SPLIT. - IMPROVED EEPROM DATA VERIFICATION. FOR SOFTWARE DEVELOPERS & MACROS - The "TQX;" command now bypasses other command processing delays to provide a more real-time response during "TX;" / "RX;" command transitions. - DUPLICATE "TX;" COMMAND while in transmit mode no longer exits transmit. - ADDED "EE0;" command to reset all radio state and menu parameters to defaults, with the exception of factory calibration data. - ADDED "TQX" GET COMMAND (extension to "TQ" TX status query): If the GET query is "TQ;", then the K4 is considered to still be in transmit mode during the S-meter holdoff time (300 ms), even though receive audio can be heard. If the GET query is "TQX;", then the S-meter holdoff time is not considered to be part of the transmit state. This allows an application to find out more quickly when actual RF transmit has ended, which may result in a more responsive user interface (when playing DVR messages, for example). - ADDED "AG$+nnn" (AF gain increment/decrement). - ADDED "VC" command to properly handle configuration of per-mode coarse tuning steps. "VT" command also improved to correctly handle A/B VFO swaps, etc. - IMPROVED "#HWFC" command to allow modification of waterfall color mode for both panadapters on the external monitor. __ 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 Message delivered to turnb...@net1.ie __ 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 Message delivered to arch...@mail-archive.com

Joel; It’s worth the look. We have most apps for both Windows and Mac.

[Elecraft] K3 RF meter behavior has me confused - help please?
Hi all. I'm new to HF, new to the K3, and relatively new to ham radio so please go easy on me. I only have my Technician so I've been listening a lot more than transmitting. I completed assembly of the radio about a year ago but left out the KPA3 until I was sure the radio was working correctly. (Did I mention this was an old kit I got from a SK auction a year ago?) I decided this past weekend to install the KPA3. Installation went perfectly, the radio passed its TX calibration and I started looking at more power. Now something odd seems to be happening. I've included the power calibration results below for complete information. K3 TX Gain Calibration data written on 2022-12-14 at 17:04:45 K3 Serial Number 00746 K3 MCU version 05.67 on COM9 at 38400 bit/s Elecraft K3 Utility Version 1.20.1.15 1900 kHz TXGain LP 36 3750 kHz TXGain LP 21 5336 kHz TXGain LP 28 7150 kHz TXGain LP 35 10125 kHz TXGain LP 30 14200 kHz TXGain LP 16 18110 kHz TXGain LP 19 21200 kHz TXGain LP 14 24930 kHz TXGain LP 13 29000 kHz TXGain LP 21 52000 kHz TXGain LP 19 1900 kHz TXGain HP 30 3750 kHz TXGain HP 36 5336 kHz TXGain HP 48 7150 kHz TXGain HP 56 10125 kHz TXGain HP 38 14200 kHz TXGain HP 18 18110 kHz TXGain HP 13 21200 kHz TXGain HP 10 24930 kHz TXGain HP 08 29000 kHz TXGain HP 18 52000 kHz TXGain HP 05 I'm running the output to a wattmeter from there to a 50W dummy load. When I key my paddle no matter how much power I set the amp to all I get as output on the onscreen RF meter is between 10 and 20W. The wattmeter seems to be registering correctly - as I increase power the output watts increase. If I transmit voice the onscreen RF meter will display up to 100W depending on the volume of my voice and the wattmeter appears to be reading correctly. Please note: I've made sure all my CW CONFIG settings are correct, and I'm sure I've got the radio set to the RF meter and not the ALC meter. Is there something I'm not understanding about the onscreen RF meter operation, or am I doing something wrong? Are there other tests I should be running? Thanks in advance for your patience! 73, Adrian KJ7SOY __ 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 Message delivered to arch...@mail-archive.com

[Elecraft] KX3/PX3 vs FT-710
On cyber Monday I picked up an FT – 710 for a great price of $1050. If this would’ve been my first radio I probably would I fell in love with it,, but unfortunately for Yaesu it was my third radio. 1=IC703, 2= KX3/PX3/KXPA100, 3= FT710 The display on the FT 710 is beautiful, but unfortunately I have to put on reading glasses to use it, whereas my old KX3/PX3 I can use without reading glasses in my camper. The audio output on the 710 was excellent for my OM hearing. But to me the background noise on the KX3 seems just a little smoother, not sure how to describe that? The PX3 panadapter puts the Yaesu to shame, Yaesu has a lot of work to do on their approach towards a panadapter Elecraft has the end-user in mine on their panadapter . The adjustability of frequency input was kind of a pain on the Yaesu. Very easy to adjust what you want on the KX3 via tapping the rat button. Antenna tuner?, Well we all know who the winner is there. And the winner is? The KX3, the Yaesu is on his way back to GigaParts. PS if you’re looking for a good radio on a budget I would recommend Yaesu, they do need a lot of firmware updates to make it a better user-friendly radio 73, KC9NRO -- Have a Great day!
