Hermes Lite2 TX 100 mw un 20 meters

[Fer Nando]

Greetings to te grup. In the first test carried ou with artificial load with the Hermes in TX, observes that in the 20 meters banda and nearby, the power of 5w does not come put, specifically in 14.160 MHz about 100 mw, in the nearby banda It does not reach 1 w. Allí others with 5 w. It was tested with the latest versión of Thetis and the previus one, the pertinent adjustments were madre in the software and the problema persiste, muy profile was even tested in another Hermes and It worked correctly there ( after changing the audio ).

Following advice from this forum, It was tried with a key and the problema persiste, I M afraid It s manufacturing defect.

Sincerely ea4dir

Hi EA4DIR,

This is a very unusually problem. It may be possible to see this problem if you have the wrong filter selected for 20M. For example, if the 80M filter is selected, it will attenuate the output for 20M. Can you share a screenshot of your Thetis N2ADR filter selections?

You could also see this problem if the 20M filter is bad or has gone bad on your N2ADR board. If this is the case, the same filter is used for 30M and 20M. Do you see the same problem with 30M? Can you temporarily set your N2ADR filter to use the 17M/15M filter for 20M and report if the problem goes away?

Another possibility is that you have some AMP protection/limitation enable on 20M. There is a screen where you set the maximum expected output for PA. Can you share the 20M settings for that?

Since you are are seeing 5W on other bands, your problem must be related to the N2ADR filter, filters settings, or 20M software settings. If we determine it is the N2ADR filter board, we can arrange a fix or replacement for just that board.

73,

Hi EA4DIR,

Please respond to the Google Group, not directly to me. Your filter setting is incorrect. Please see this video at time 2:03:

https://www.youtube.com/watch?v=97UZi8qYAKM

Since this video was made, there are custom versions of PowerSDR and Thetis for the HL2. You should use one of those versions. See the software wiki page:

https://github.com/softerhardware/Hermes-Lite2/wiki/Software

https://github.com/mi0bot/OpenHPSDR-Thetis/releases/tag/v2.9.0.6

Search the group via the web interface for PowerSDR and Thetis. This can help determine which version to use:

There are more videos on YouTube. Search for Hermes-Lite:

I attached and imagen of how I had to leave the filters. Sincerely Fer Nando ea4dir

You also need to install the correct HL2 version of Thetis. Note on Reids attachment the push button to properly configure the filters. There are other changes for HL2 that are made that you will have to resolve manually if you continue to use the unmodified version.

Hello, I comment that It only does TX 5 w by selecting band. 6, the correct configuration does not reach 2 w.THIS DOES NOT WORK THE PLATE IS DEFECTIVE, I HAVE BEEN WITH THE SUBJECT FOR MORE THAN 20 HOURS IN 3 DAYS. I DEMAND THE WARRANTY OF THE PRODUCT, NOTHING MORE OR NOTHING LESS. REGRET BUYING THIS PRODUCT.

EN Español

El HL2, tanto con el Thetis como con otras aplicaciones en 15 metros en TX tiene unos 100 mw, las bandas cercanas unos ,2 w. En Thetis con la configuración indicada para el HL2. Solo se consiguen los 5 w cuando se hace una configuración incorrecta seleccionando la posición 6 del filtro. La placa parece que llegó defectuosa. Tan difícil es explicar esto...

Atentamente

Hi Fernando,

The piece of information I am missing is if the bad filter selection affects two bands or just one band. It will be conclusive evidence if it affects two bands. But if the same bad filter selection only affects one band, then we would have to look at other software settings.

I am fairly confident that this is a bad N2ADR filter board, not the HL2 board. There is no scenario I can think of where just the HL2 will produce low power on just one or two bands. You have three options you can proceed with:

1. Contact Makerfabs and request just a replacement of the N2ADR filter board.

2. Return everything to Makerfabs for a full refund. I think you are still within the window of time to do that.

3. Continue to debug in this group. One possibility is that a relay has gone bad during shipping. We have relays available for replacement if that is something you are interested in.

Please let me know which option you'd like. If 1 or 2, contact Makerfabs immediately. Also, let me know and I will also contact Makerfabs.

Please also read the repair guidelines:

Hi Fernando and Group,

In private e-mail, Fernando is not sure about a full refund or replacing the N2ADR filter board, or we don't understand each other. We are having difficulty communicating. I'd appreciate help from anyone who speaks Spanish in this group.

I'd like to test if it is one filter selection which is bad or something else. Fernando, please report the output power on 30, 20, 17 and 15 meters when the filter settings are as shown below. Please report values for all 4 bands requested.

Next, change your filter selection to what is shown below, and again report output power on 30, 20, 17 and 15 meters.

73,

Steve

Good morning, indeed I wrote 2 where. I Wanted to select 1, the attached text sabes that what want is the change of the board, in terms of the Tx powers at 30 m and 17 m, Witherspoon their specific filtros they do not reach 3 w. The Rush, each person Will hace their reasons. I think there are misinterpretations due to Google Translate. Allí the Best.

Hi Group,

Fernando sent some pictures via private e-mail which I have included below. Now it seems as if it must be a software problem as there is only no/low power on 20M. There is expected power on 30M which shares the filter with 20M. Thetis/PowerSDR experts, can you think of anything which might cause this?

Fernando,

Please try with the alternate filter setting I shared in my last post and report power output for 30, 20, 17 and 15 meter. You should delete or reset your Thetis database. You should also use the version of Thetis with Hermes-Lite 2 support, and select Hermes-Lite 2 as your radio.
https://github.com/mi0bot/OpenHPSDR-Thetis/releases/tag/v2.9.0.6

Finally, please try other software (SDRConsole, Quisk, SparkSDR, etc.) to check if you see the same problem.

https://github.com/softerhardware/Hermes-Lite2/wiki/Software

We are really struggling to communicate. Are there any Spanish speakers in this group willing to help?

Hello everybody,

Has Fernando tried a database reset ?  I had a similar problem with the same Thetis version and it was solved with a simple reset.

Just my two cents.....

Hi Fernando,

Please try this v2.9.0.8-beta1 latest release (https://github.com/mi0bot/OpenHPSDR-Thetis/releases). This has changes which are specific for the HL2.

https://github.com/softerhardware/Hermes-Lite2/wiki/Thetis-Setup should give you the basic setup details.

The screenshots from Fernando doesnt look like v2.9.0.8-HL2 Beta 1 . Maybe there is the mistake.

[Kristofer Danner]

I agree, the title bar would show if it was the version for HL2, like this image.

It seems like more than half of the threads in this group are about Thetis misconfiguration, more often than not wrongly blaming the hardware. Is there some kind of documentation missing which could help alleviate this, or are people just ignoring documentation?

Don't know if this has been solved, but I'm willing to help the spanish speaking community on this and any future issue.

Hi Ramon,

Thanks for you offer to help. Someone else with some Spanish fluency contacted Fernando privately. I will keep you in mind if a similar situation arises in the future.
