Re: ALC 100 and NO TX output (AFT5M31N) LDMOS

 

Thank you for the extra photos Real, I will check for this also in my tests this evening.

Ciao for now,
Scot

Scot, good match plan.

I read on the forum that unplugging and reconnecting the ribbon cable can solve the problem, on my side it does not work

it is mentioned that the ribbon cables are of very poor quality.

I am sending you a photo that I had taken, you may notice that the contacts are a bit dented.

THANKS

Re: ALC 100 and NO TX output (AFT5M31N) LDMOS

Real,
My radio shows same problem as yours. I can hear on SDR faint signal also.?

The ATU is a simple affair from looking at the chip (BU2152FS) on board - a simple SIPO serial in parallel out driver chip, looks like the ATU has no "processor or memory" on board. Just control lines from the main board. (I assume controlled from a software file)

The ATU contains the LPF array and a set of ATU relays. The long row of coils and relays are the LOW PASS FILTERS, and the 6 coils near the BNC ANT socket are the ATU.?

The coils in the middle are the SWR bridge coupling I believe, and the few small chips and transistors are control logic and probably signal conditioning to send ALC and SWR/PWR signals back top the main board.

Tonight I am going to put the oscilloscope on the radio as see where the RF signal is being lost in the ATU board.?

**IDEA**

I read that when you disconnected the ATU ribbon cable the RF power and ALC showed around 16Watts? ... I tried, mine said similar (maybe 15 watts) , BUT I think this is a lie and a blessing.

I think it is the radio main board ALC measurement and RF power ADC reading no signal from the ATU which makes a fool of the software and it thinks full power!) The ALC on x6100 was always backwards? 100 off 1=full on. So, lost likely the ALC signal from the ATU bard being missing is causing the reading. The signal must be active low not high.


So in the next 24 hours I hope you offer some results of my signal tracing.

The options are:

1. LPF is not being selected and the signal is dumping before it gets to the SWR / ALC bridge,
2. The RF output is broken (unlikely at this point because a peculiar pressing of ATT and PRE buttons made the power come back and output transistors don't often break "intermittent")
3. The ATU software settings on the main board file system are corrupt and not powering the correct LPF.


I do not think the ATU is the issue... the ATU would just cause HIGH SWR not power loss reading. If you think about it, the ALC gets it signal from the SWR bridge "before the ATU"??


RADIO--->OUTPUT AMP ----->LPF ----->SWR BRDIGE/ALC------->ATU (bridged or active)------->ANT

? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?TO ALC/POWER ADC

My money is on a corrupt ATU settings or firmware file or a broken really in the LPF system/tx relay or similar issue.

I read that a factory reset is NOT what you think, it wipes only user preferences! Need to downgrade the baseboard and FW UI to prove the firmware is not the issue!


UPDATE..?
I downgraded fully to FW 1.5 and this did not work. ?If there is a configuration file for the ATU then the FW upgrade/downgrade is NPOT replacing it or that is not the issue.

Re: ALC 100 and NO TX output (AFT5M31N) LDMOS

I tried your find on my side, it gave me no results + my alc is still at 100 and no power on my dummy load, I noticed that there is a small audible transmission with my SDR dungle


Re: ALC 100 and NO TX output (AFT5M31N) LDMOS

 

Update to the last, this worked several times then the TX power was gone again.?

Time to fault find the ATU.?


Re: ALC 100 and NO TX output (AFT5M31N) LDMOS

 
Edited

OK... I "THOUGHT" I HAD SOLVED THIS...?

This morning whilst operating CW and after playing with ATT and PRE amp I noticed ZERO - no power from the TX. The audio was fine as usual.

After Real's last message I played with ATT and PRE and the ATTENUATOR appeared flipped... When I enabled the RX attenuator, the TX POWER magically came back!!

Also, I feel it is a BAD IDEA to try and drive the radio 10W with the internal battery!?

Reduce power to 5W when using internal battery and hacked FW. The 10W ?CANOT WORK! its a myth. The power rail cannot support it even if the FW can.


My final was not blown, the ATU/ATTENUATOR and PRE appears messed up.


Thanks
Scot!


Re: ALC 100 and NO TX output (AFT5M31N) LDMOS

 

Thank you Real for your reply!?

I will reflash the firmware first to see if this is an issue then!?

Maybe removing the battery for a long time will reset the ATU who knows! ?
I have much test equipment so can investigate also.?


Thanks
Scot

AFT05MS031N OLD PWR Trans inside x6100
drain - source = 3.96mohm

seems good

After removed from x6100
drain - source =3.96mohm
drain - gate = infinit
seems good

when atu board not connected?
and quick tune from cat wsjtx
display 16.2w see picture
?
////////////////////////////////

I believe that the problem comes from the atu which selects the wrong filter, my problem appeared after a transmission in ft8 (CAT). I checked the fuse, I replaced the pwr output, checked the bias of the transistor, I checked all the atu relays, I think there is a bug with the firmware code which activates the wrong atu filter, it would take a trick to erase the memory of the atu?



Re: ALC 100 and NO TX output (AFT5M31N) LDMOS

 

Hi Real,

did you fix this??

Do you have a photo of the FUSE location??

I also have ordered new final output.

Thanks

I had the same problem with my x6100 after an upgrade. I charged it, run it down to dead 4 times and that seemed to have fixed it. I now have a full battery charge showing when charged.?

I can try again. but the firmware shown in attached picture looks to be the most current.

Thanks Dave but not necessary.? It operates fine, its just that pesky Icon and blinking light.??
Update, I did another Firmware update, same results, no change.
Charging with OEM wall wart same results.??
I'm going to see about sending it back.

Re: EMPTY RED Battery icon after charge.

 

George N2GWK,

On another thought, use your X6100 with the int battery and see how long it last on the full charge.? I see about 2 hours of operation, 90% rcv.? If your X6100 runs this long I would think the internal battery is being charged correctly.

What voltage are you charging the int battery with.? My X6100 when the display shows the int battery to be 8.2V I consider it fully charged.? If the charging voltage you are using is say low, 11V, the LED might not indicate charged.? Just thinking.

I use an ext 13V battery with my X6100, wait for the LED to stop blinking and then charge for another 2 hours.? Then the int battery voltage reads 8.2, but drops quickly to 7.9V when in use.
