Fwd: Re: [Kenwood] TM-221 resistor locations for all freq xmit?

Fri Jul 9 18:18:43 EDT 2004

Hi agn,
Tnx to all who sent me the e-mails which all pointed to the following. Now 
comes the part
as how can I locate on the board which is which resistor. I don't have the 
service manual
which I assume shows the location of the resistors. I do have the radio 
apart and on the
bench and no markings on the board as to resistor numbers.
Would appreciate if someone had a service manual I could copy or buy. Also 
have fax here if
someone can fax me would be another way. Have not checked with the manual 
guys that sell the
copies yet but will be the next step if needed.
Agn tnx for all the help so far. Will be doing this to get on the MARS freqs.
