That is exactly what I am thinking. I would confirm continuity with a meter and make certain the cable checks out. wrote:

Hi Steve, Each of my iambic keys have their own cable with stereo plug. Possibly the cable provided with the LAB599 may be the problem? John W9QP Sent from AT&T Yahoo Mail for iPad

Hi John - Are you using the same cable for all the keys? Just trying to think through the troubleshooting. 73, Steve de W0ARK wrote:

Hi Everyone, Having a little issue with changing from straight key to iambic in the menu. My straight key works when in straight key mode, when switching to iambic and plugging my iambic key it

It's in the TX-500 manual, Menu Functions, Item 23, TX Metr. Of course Tim's instructions provide more detail. Hopefully, over time the TX-500 manual be updated to provide greater detail, maybe even

Lab599 wrote this in a FB response. " The ALC in the Discovery TX-500 transceiver is essentially protection against high SWR and is configured to prevent the failure of the output stage. At high SWR,

Dave, There was an earlier issue with the TX capability on all frequencies within the 60M band. Although I am not a user of that band, I believe they were able to fix that in firmware update 1.04.07

I would like to use my TX500 as receiver for 630M band signals (around 470 kHz), however, the current band assignments (for receive) cut off at 500 kHz. This would of course require appropriate amount

I have requested via the Lab599 Twitter link to have a Voice Beacon Mode added via a future firmware update. With interruption via the PTT connection. 73, Henry - K4TMC

Is the CW/CW-R freq shift problem fixed? ?My radio changes frequency rather than side bands when hard press CW to toggle CW-R. David. W3GZS

The description in the manual ("CW side tone pitch matching indicator") is a bit confusing, sorry. In CW mode, w hen your receiver is exactly on the sender’s frequency, the TX500 will display a

I read advice from Lab599 that each firmware update needs to be done, but that the sequence isn't important. Seems odd, but there you go.

Just wrapped up an extended outing with the TX-500 doing primarily digi modes.? Was very pleased with how the rig performed, but have yet to figure out how to monitor ALC levels to keep from over

Apart of the recent notch and CW changes, a lot of small stuff has changed as well: Lab599-TX500-User-Manual-EN-v1.07.00-04.2021.pdf -> Lab599-TX500-User-Manual-EN-v1.08.01-06.21.pdf (

For those of us that pay to have the manual commercially printed, would it be too much trouble to provide what pages have updates? ????? ??Sent from my iPhone.......?

I have yet to do a FW upgrade. I thought I read somewhere that a firmware? upgrade requires a sequential upgrade of each release starting with the first... However, I did not read this in the manual,

A new Firmware v1.08.01 is now available at https://lab599.com/downloads/ ( https://lab599.com/downloads/?fbclid=IwAR1w1-80_FxoaUCZxBrXiphNvD1VFsnZG6Wv_gJw793bn4iOE8STtjK0fvs ) Added CW Beacon mode

I think that it was an older version of Linux that didn't have some of the dependencies for that package. Eventually I just used windows. I do think it was 64 bit, a Toshiba portege that is running
