Kenwood TK 6110 No Rf Output

[midstate33]

OK Got this pretty clean TK 6110 & want to use it on my local VFD, receives great, transmit is barely present but good, no rf output on a Bird wattmeter, anyone know if they had a common failure for this
symptom in this model, I know the finals were being run BTW all the time, any help appreciated, tnx

Start with your basics, make sure you have a good antenna and good feed line (no shorts) and check your programming.

Put an ammeter on the power lead. Should pull about 13 amps on transmit. If this is the case, it is making TX power, just not getting out to the bird. Pin diodes, DC bias to the diodes, and the antenna connector are just about it after the final. (check your test cable too!)

If there is no increased amps on TX, then the PA is defective (bad component, burned and open solder joint or trace).

Thanks all for the info apparently bad rf transistors, item for sale or trade too expensive to replace the
transistors...
