OK Keep in mind that for the most part, the marker generator is strong enough to be used as a built in RF generator. Great for tracing signals. Most rigs will see about an S9 +5dB to +15dB on the S

Thanks Bruce.? From? the main circuit diagram the antenna signal wends it's way from the SO239 to AGC switch <already checked this is OK> to an inert tuned circuit (L01/C07)<'9mhz trap'> on the

Yes, that really sounds like a bad solder joint somewhere. Whether it is on the RF board ormot is another matter but since the marker is weak and so is the received antenna signals... I'd get the

The marker generator works but at a low level across all bands although maybe louder on some - it will not move the S meter but is clearly audible and fades out when RF gain is turned fully

Thanks gentlemen for the circuit information - as always appreciated

Too small Try this PDF one

The attachment is the 2154 board schematic

Very good. I also have a MKIII ZD with that newer RF board. I think I have the schematic for it somewhere. Does your marker generator work well enough to use as your signal generator.... for the most

Hi Alistair, I just uploaded the manual you need for PB2154. Please look in the Files section Folder 7 for FT-101ZD_MK3_serv.pdf. Look at Page 5-8 Adobe page 9. 73 Roger VE7LB

Thanks so far.? I have cleaned and verified that the Attenuation switch is clean and working as it should.? Further research inside the equipment and the internet I find that the RF board in my

First thing to do is get a little spray can of DeOxit. Turn the radio on it’s back with the front panel up. Hold a rag near the attenuator switch assembly to stop any over spray on?the outside of

Hi Kenoli and thanks Roger for finding the a better SM Like the song goes “we only just begun “ My xyz and I are still unpacking and I have the boats and our cabin to winterize and I better also

Hi again Kenoli, I also could not find the Carrier Balance procedure in the Service Manual I have on hand. I did find a better SM copy and have uploaded it to our FILES section here. Look for CARRIER
