LDG AT100Pro II locks out when TUNE button is pressed

Rej All Messages By This Member #2163 Hi Maybe someone can help ? I've had this LDG AT100pro II tuner for about a year now. ? It has worked fine UP TO NOW. ? Problem is that when i short press the TUNE button to toggle the ByPass mode, the PWR and SWR Led's light up full scale and all the panel buttons become non functional.? This all WITHOUT keying transmitter.? Keying transmitter does not resolve the issue. ? I'm using a Yeasu FT891 without any control cable to the tuner. ? I reset the tuner by removing the power, wait 30 secs, and power up.? The buttons are then responsive again. Using Func + C Dn i can confirm that the tuner is in SEMI mode. ? After the power reset ... - The Ant button correctly switches between antennas - The C Up, C Dn, L Up, and L Dn buttons works as expected, changing the C and L values. - The Func button itself works, with the Led display toggling between arrow up and arrow down. - Func + L Dn correctly goes through the SWR threshold values, and i set it to 2.0 - Func + L Up correctly toggles through the pwr setting which i set to 100. - Using the FUNC button with the TUNE button, both short press and long press, work as expected -When i MEDIUM press (without the Func mode) the TUNE button after a reset, the PWR Led's briefly all light up, followed by a quick sequential scan of all the Led's.? ? In all the above, the panel buttons REMAIN FUNCTIONAL. ??? - When i LONG press the TUNE button (without the Func mode) , after a reset to get the relay settings, the PWR Led's all light up (but not the SWR Led's) and the panel buttons go dead again - When i SHORT press the TUNE button (without the Func mode) , after a reset to toggle the BYPASS mode, the PWR Led's AND Swr Led'a all light up and the panel buttons go dead again. ? Again, this has cropped up recently. Can it be a memory store issue ? How can i force a factory default config reset ? Is there some firmware update ? ? Any hints would be appreciated. ? -- 73's "Rej" VA3DWH
EA3FNM - Pedro S - Barcelona - Spain All Messages By This Member #2171 Hi Reg, Could be a problem of the TUNE switch? Check if ot works fine. The at100proii can't be reset but i had one experience time ago with my at100proii and putting out and again in the eprom the memory was reset and it did not work fine. I made the same procedure (eprom out and in again) and the ldg resets and works fine again. Regards!!
Rej All Messages By This Member #2180 Thanks Pedro. ? The TUNE button (hardware) is not the issue, as it works correctly "re: ... -When i MEDIUM press (without the Func mode) the TUNE button after a reset, the PWR Led's briefly all light up, followed by a quick sequential scan of all the Led's ..." ? I will attempt removal of the eprom as you suggested. ? -- "Rej" VA3DWH
Rej All Messages By This Member #2182 Well i didn't pull the chip out.? Couldn't find my chip extractor. ? However, a few more notes about this. ? 1-) when i set the mode to AUTO TUNE, and transmit 5 watts to an unmatched antenna, the unit attempts to tune but when i release the transmit the LEDs stay lit with the pwr and swr values.? The panel buttons go UNRESPONSIVE. ? 2-) with the cover removed, i can now hear a squealing noise when i transmitted and the panel buttons go numb;? like a relay buzzing. Even after transmitting the buzzing continues until power is removed. ? For info, the PC Board is marked with AT-100 Pro II? v1.1 The processor chip is labelled 100PROii10 ? -- "Rej" VA3DWH
Rej All Messages By This Member #2183 ISSUE RESOLVED !!! ? I got in touch with support at LDG. Someone named Mark suggested i check the power supply. I was using 8xAA cells in holder pack to give me 12volts ? Turns out the AA cells had drained to 1.0 v each, totalling 8 volts at the plug instead of 12. Put fresh cells in and 'presto' it's all good again. I can't figure out how these got drained so quickly. ? My understanding is that there is little to no consumption, unless the tuner is actually tuning, due to latching relays. I usually unplug the power unless i'm active on the rig. ? Prior to that, someone had also suggested i do a reset by holding the FUNC+ANT+TUNE keys before powering up. Does this actually do a reset on this model ?? ? Gotta say that customer support was great, and the guys are good at troubleshooting remotely based on provided info. ? -- "Rej" VA3DWH
O-B-1 KJ7WUZ/WRHW845 All Messages By This Member #2185 When "plugged in" the power connector should disconnect battery pack. Have you been operating POTA or SOTA? mobile with it in a backpack? Perhaps the TUNE button was getting pressed in the pack?? I am considering installing a SPST micro toggle switch in the leads to disable the battery pack connection until I am ready to use the tuner. toggle quoted message Show quoted text On Mon, Oct 21, 2024 at 5:32 PM, Rej <va3dwh@...> wrote: ISSUE RESOLVED !!! ?

Vlad Z All Messages By This Member #2186 This is how I ensure that internal batteries are disconnected when not in use.. ? With my LGD Z-11Pro, I had battery pack wires terminate with the same type coaxial connector as the power connector from external source. The wire would come out through existing opening in the back panel. Either I'd plug in the external adapter, or the connector wired to the batteries container inside the tuner. This way battery coaxial connector is unplugged when not in use. The tuner has a dangling a little tail - not ideal, but not a problem.
Rej All Messages By This Member #2187 Yeh I didn't think the unit would drain the batteries that quickly, seeing that i'm usually in BYPASS mode anyways. Oh well. ? Gonna either install an SPST switch, or make a splice into the FT891 power cable. ? -- "Rej" VA3DWH
Dave Garber All Messages By This Member #2188 instead of splicing, just add a dc cable to the power source of the radio Dave Garber VE3WEJ / VE3IE toggle quoted message Show quoted text On Thu, Oct 24, 2024 at 9:59?AM Rej via <va3dwh=[email protected]> wrote: Yeh I didn't think the unit would drain the batteries that quickly, seeing that i'm usually in BYPASS mode anyways.

Rej All Messages By This Member #2194 Yeh, i had thought of that, except that i'd now have an extra set of messy wires going to the battery and getting caught in stuff. Instead, the splice would terminate with a connector where the tuner (or sonething else) would connect into. It could end up becoming a bus system to supply other 12volt devices near the rig (eg lighting, usb charging etc) ? -- "Rej" VA3DWH
