Question about Vertex FNB-33, YAESU,FT-11R,FT-41R,FT-51R, 4.8v 1700mAh NiCd 2-Way Radio

Open Question

FT-11R with no RF Out signal

My FT-11R does not transmit anymore, no RF as also no red TX Led when
pressing the PTT button.By interchanging boards with a good FT-11R, I
found out, that the RF unit is not working.
My local dealer has no repairing parts anymore so does Yaesu.
Can anyone help me on this? Does anyone know where to get a repair manual with schematics partslist and layout to repair it myself.

You can order the parts from Yaesu or your local Yaesu dealer can do it for you.

figured out how to solve this, with the radio off, push and hold both up and down scan buttons, while powering the radio on. This will fix the problem.

I CAN HEAR THE DISPATCH BUT THEY CAN'T HEAR ME. WHAT IS IT ? IS IT A MIC,? PLEASE.....HELP. I HAVE A RADIUS SP50 MODEL.


First, make sure the battery is fully charged and red LED TX indicator is on steady as long as you are holding the PTT button. If the red LED blinks while you are transmitting, the battery is not charged, or is bad.
Otherwise here are some common problems with the SP50 that can cause that issue:
Bad PTT switch
Internal microphone is bad
Speaker/microphone is bad-if used
Jacks are bad
Transmitter power amplifier is bad
Antenna is bad

Contact a local dealer for proper diagnosis.

Cx80 stuck in rx mode , power cycled, swapped batteries, changed channels, will only swtich to tx when ptt button pressed, otherwise always in rx mode, other radio from package works fine


But thats how a walkie talkie works, it stays in Receive Rx mode UNTIL you press the PTT button,, then it Transmits Tx, and when released it goes back to Rx, receive?

Check the connection going to the BNC antenna connector from the circuit board. I have seen this wire break before. KB9EKH

Hi,

Your concern is no transmit and no red transmit led -

If there is no receive likewise, then probably problem in the PLL/VCO section or 9V voltage regulator TR23 (2SC1096) or Zener diode D22 (9.1V).

If the receive is normal, then possibly any of two (2) faults:
1. microphone/PTT switch and/or the mic cable specifically the wire connected to pin# 3 of the connector; or
2. +8V switching transistor TR21 (2SA733P).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Kenwood ts-450s - cannot tune and no ptt


This is usually due to a stuck or shorted ptt line. I have repaired a couple of these and it was the same component each time. The packet TX transistor Q65 shorted causing the radio to power up in TX inhibit mode. Transistor Q65 is located on the underside of the IF board under the ACC 2 connector. This switching transistor is used only for tx (pin 9 of acc 2) and no other circuits depend on it. It can be removed completely if you don't mind not having ptt on acc 2.
This seems to be a common problem lately, I hope this helps you.
