Does it work?

Today I'm going to connect the Xiegu X6200 to the the XPA125B and see if this actually works correctly. Stay Tuned!

Great video. I spoke to Xiegu about the ALC not responding through the L4001 cable and the XPA125B, and they said look for the first firmware update.

Nice looking radio, great Work, tnx Man!

[MAMAN]

Great demo brother! If I wasn't broke currently, I'd be buying these two lol...

Lots of good bench space in the kitchen lab

Good timing as several on the x6200 list are having difficulty with this configuration. SSB audio thru the amp is being clipped suggesting the ALC is not working and the amp is being overdriven as I think you have demonstrated. The problem appears to be in the 6200 not the XPA125 as it works fine with the x6100.

Something odd. On 160m when you TX the PA swithes to 75/80m (look at 3:16) ... looks like something is wrong there, at first I thought it was due to 8W you injected but when you decreased to 5W the issue is remaining.
I have the combo G90 + the amp and I love it. Since last update of G90 I must turn power to 1W on 15m otherwise it overloads the power output...

I wish they would make a 20W+ version of the x6200. I like the x6200 but I don't want to also have to buy an amp. That amp is very appealing though.

Noticed the Amp got to full output straight away. Didn't creep up like it's boss does.

Recently got a 6200 and this amplifier. The manual says keep it <2 watts for the amp input or damage may occur. Finding that the amp tuner is quite finnicky so far and isn't a tuning phenom, like their radios have proven to be. Lots of flashing messages of high return RF, even with 1:1 choke on either end, somewhat puzzled and skeptical at this point Further testing this week.

Thanks for the great video. I just got a Nissei DG-503 second hand and was curious if you ever compared/calibrated your MFJ-849 against a Bird or something else? I did and mine seems to be spot on, but was just curious. 73, K8JLW

Nice test. I did see the auto mode acting strange. Should select manual mode . selecting wrong band may cause unwanted harmonics .All the amps I have, Have different output power on different bands and different from amp to amp. Even when tuned, A tube amp does this. most of the amps I have, like the middle bands the most like 15/20 meters. Now I know what you do on cold days. Key up with power into dummy load, make some heat. I am in NY and woke up cold. 56F . crazy cold and just back to field day we breaking record heat . now I am turning tubes on to do FT8. 10/12 meters been bad few weeks now. But had a FT8 on 6 meters ! just the outher day 20 meters was poor and noisy with heavy QSB but 15 meters going nice and 17 meters was ok. strange bands in NY. 73's

[nkkri]

Will the amp work on other QRP radios like the FT817 ?

[unclemikeyplays]

Has Xiegu said anything about that weird "warm-up" phase for power?

[thuff]

Looks like the amp get to full power faster then the radio. Hum.

Do not buy a Xiegu XPA125B or any Xiegu product! This amplifier was originally introduced with a good design using a pair of RD100HHF MOSFETs to easily handle 100W. After a few years they started selling units using the a single AFT05MP075N rated for 75W without any change to published specifications. You can push these amps to 75-80W but they are now really 50W nominal amplifier to achieve the same IMD rating. For a company to engage in these unethical design practices, I'd strongly recommend to never buy any Xiegu products! This is the same practice that Huawei tried when they started to gain some market share in the US with their phones and tablets.
