It sounds like there may be an issue with the LCD display on your Yaesu FT411E radio. If the display is not working, it may be necessary to replace it in order to restore full functionality to the radio. You may be able to find a replacement LCD display online through electronics parts suppliers or through radio repair shops that specialize in Yaesu radios. Alternatively, you could try contacting Yaesu directly to see if they have any replacement parts available. If you are not comfortable with repairing the radio yourself, it may be best to take it to a professional radio repair technician who can diagnose and fix the issue for you.

Yaesu 3100 transmit problems

There are several reasons you may not be able to transmit with the FTM-3100R:

1) Your antenna is not matched to the frequency of use and presents a high SWR. The 3100 protects itself from high SWR by refusing to transmit
2) You have somehow enabled the busy-channel-lockout feature in the setup menu, and you are operating with an open squelch
3) Your DC power supply voltage is too low to support transmit current
4) You are transmitting with too low a power setting and the receiver cannot hear you
5) You are attempting to transmit to a repeater that uses a CTCSS squelch tone, and you do not have the proper squelch tone configured

Both of the LEDs to the left of the display should turn red to indicate you are transmitting. If both LEDs turn red, your problem is likely either #4 or #5.

After Flash Update (v0227) will not xmit proerly

I would flash it back to the older version. Double check you have the correct firmware. This almost sounds like the incorrect version for your radio.

LED digits not working

not sure if yaesu has the parts if not look on ebay

Ft-950 I somehow made the red tx light start flashing.It did this 2 years ago,how do I make it stop? I already did the resets.I do not remember how I stoped it 2 years ago. can tou help?

If a "reset didn't do it, you'll need to contact Yaesu tech support - they're very helpful (but best not to call early Monday or late Friday).

It sounds like perhaps you have CTCSS turned on so it's blocking received signals that aren't using sub-audible tones. Make sure the "TSQ" indicator is not showing. Most Yaesu radios have the SQU or "T.SQ" option easily found in their menu structure..

I need a memory battery for a ft 50r both sides are sorderd the main board

I just had my FT-50R repaired due to a overheat issue with a reverse polarity diode. When I asked Yaesu to alao check my Yaesu for the memory battery I was told by their top technican that the radio does not have a memory battery in it. I hope this helps.

Yaesu VX-3R ham radio will not turn ON!!!!

Even though this is several months old, I thought I would post this reply. I had the same problem when I ran the battery completly down. The charge light didn't come on and the unit would not turn on with the power or battery. Sent the unit back to Yaesu for warranty work and they replaced the switch board. Unfortunately after I got it back and ran the battery down again..... Well, it's back at Yaesu AGAIN! Looks to me like there could be a problem with the power circuit being overloaded when it tries to charge the flat battery!!
Nice little rig, but it may be for sale once I get it back!!
