Hi,? this is funny, because they told me a while ago something completely different :-) (See attached screenshot) So I guess there are some missunderstandings.... 73, Stephan -- DF6PA Stephan Forth

Well...that is interesting. I always thought that new firmware updates incorporated all of the previous changes that were still good. My TX-500 only had the v1.04.05 update prior to my updating to

*UPDATE on my TX500:* The TDA7056AT replacement chip arrived quickly. I used to plan to send it to a SMD specialist for the swap, but more than one of my fellow hams told me that it is not that

Just got an email reply from Lab 599 support.? The firmware upgrades have to be installed in order.? In other words v1.04.07 must be installed first and then v1.05.00.? It seems each firmware

Yes, firmware version 1.04.07 does allow the radio to operate in the USA 60 meter band.? Be aware however, firmware version 1.05.00 DOES NOT.? V1.05.00 only allows the radio to operate between

Henry....many thanks for your time to test and report the results....this is great sharing. -- 73, Jim / AC3B https://www.qrz.com/db/AC3B

Subsequent to yesterday's firmware update, I found a little time today to hook up the TX-500 on the kitchen table with a dummy load. I can confirm that the new VXM feature works. I was able to record

Hi Axel tnx for that. In real live, I can confirm, that I didn't have any problems running js8call and ft8 with the rig, 73, Stephan -- DF6PA Stephan Forth Licensed since 1978 TX-500, IC-703, FT-817ND

One more note on that. I made a zero beat test with a RX I know it's stable on 10 m. I can't confirm the more then 70 Hz drift in 10 sec. If that would be really the case it would run out of "zero

You might have a look on that topic here in the group as well: /g/Lab599/message/88 73 de Axel.

Thanks very much, Axel!? That's very disappointing for a Euro-900 transceiver.? A Chinese TCXO with proven zero drift in my TS-480 (which also had the same +/-4 drift), with no warm-up time at all,

Eric, Thanks for the follow-up. Yes, that may have been my problem. However, from the looks of the GX12 connector wires, I suspected a short. Plus, I had already found a shorted wire in the MIC/SP/PTT

Can confirm I updated your radio when I repaired it, so it had to be a cable issue. -- John Byerly mailto:mtnlion@...

Next time, try restarting the software after the usb cable is plugged in. It’s likely that the software only scanned for serial ports once and didn’t auto update the list when you plugged it in.

So, I started the firmware update process. I downloaded the Update Utility file "LAB599 updatefirmware 1.0.0(x64)" and the "mtrx1.05.00" file to my Windows 10 laptop. When I executed the file, I got a

I tried WSPR in the past but did not recorded it. First: The rig was switched on for couple of hours before. Two transmissions. TX with 1 W on 40 m *Timestamp* *Call* *MHz* *SNR* *Drift* *Grid* *Pwr*

I have just sent Twitter message to Lab599 requesting variable repeatability (3 - 10 sec) of audio playback message and ability to stop message via PTT. I am in process of carefully doing the firmware

Thank?you for your responses.....they are very helpful to me to make my buying decision because your responses put some ‘balance’ into how I think about this radio. Your responses ‘balance’

I wonder if anyone has run the TX-500 on WSPR for a while and noted how frequency-stable it is (or is not)? I've asked a lot of people elsewhere about this, all so far to no avail. Would appreciate

Thank?you all for your responses!!! ? I am one step (actually 3) closer to placing my order.... 1-promising news regarding Voice Keyer 2-helpful insight regarding CW relay noise 3-jump in before
