Maximum Power for TGXL

Mike-VA3MW

My 160M antenna is down for the winter and I am trying to work TX5S on my 80M SSB antenna. No joy so far and I am not surprised.

But, did you know that when you hit Tune on the TGXL it calculates the maximum wattage you can use for that tuning solution and presents it in the GUI?

Unfortunately, the 80mV seems that using a non-resonant antenna results in it being a bit of a cloud warmer based on PSKReport results. No fault of the TGXL.

Hi Mike,

Although this has nothing to do with TGXL, I suffer the same hardware problem. I only need Cliperton on 160M. I only have an 80M dipole, and my old L-4B amp doesn't cover 160M.

I have been copying them on 160M CW at about S7 and this AM on FT8 at +6.

No joy either...

I managed to work them on FT-8 once we got into Grey Line. But, if I had a resonant 160M antenna up, I would have been 20db stronger and worked them in short order rather than 3 attempts that almost made it over 2 hours.

Unfortunately they quit FT8 a couple hours before my sunrise. They were still quite strong, but I noticed most of the reports thay were giving were between -15 to -20 so my 100W and virtually no antenna don't stand a chance.

Thanks for bringing it up. Are you one of "those guys" that reads the manual, lol.

I looked up the latest User Guide I have which was for v 1.1.16 and sure enough it states, " a maximum power indicator is shown when demanded by the limits of the tuning solution". OK, no wonder it didn't stick in my brain, your explanation is easier to understand. I've edited it, so my brain can absorb this fact.

"After a tuning solution is found, the TGXL calculates the maximum wattage you can use for that tuning solution and presents it in the GUI as indicated with a red bar and MAX on the top of it."

Then I went to test this to on my setup and found out that 'm running v 1.2.11 and it does not show this. I got a tuning solution from both the TGXL front panel and from the GUI, no joy. I am running AG v4 so I believe I need to run TGXL v 1.2.11 and I see Mike you are also running v 1.2.11, so I should see this too. What am I doing wrong?

The 1K is not a limit that you see on a resonant 160M antenna but will show when trying to load a compromised antenna and or further away from the design frequency range of a normal 160M antenna cut for a particular section of the Band. As it says...its a "smart" tuner :)

Yeah, I'm running TGXL v1.2.11 and am not seeing this indicator either.

Another problem I'm seeing with v1.2.11 mentioned in another post is the bypass selection feature in the "Bands" tab under Settings>Other doesn't work when integrated with the AG.

Hi Russ, this does work for me.

Russ Ravella

Hi DL4RCE,

Thanks for the reply - much appreciated ! Which firmware versions for the TGXL and AG are you using ?

Thanks, Russ KR6W

Russ,

TG 1.2.11 needs AG 4.1.7

In TG Genius Integration tab, use the pull-down to select the serial number of the AG (last 3 octet of MAC address). Do not enter the IP like previous versions.

You might need to use the factory reset option in AG twice to ensure it is completely reset and make sure all dip switches are open on AG (down when looking at end with Ethernet connection to right).

I do have, SmartSDR v3.6.8, PGXL 3.8.4, TGXL 1.2.11, AG2x8 4.1.7

Hi Dave,

Thanks for the advice as always. Even though I'd already done all of that (including using AG v4.1.7) following advice you gave me previously, I did factory resets on both the TGXL and AG again then reconfigured them for good measure. Strangely, although it didn't fix THIS problem (max power line on TGXL still doesn't show), it did fix another problem I was having - bypass setting in the freq list not working; now it does.

Are you saying you DO see the "Max Power" indicator line using these versions ? If so, I wonder what's going on with ours ?

Thanks, Russ KR6W
