Two ideas,<br>
<br>
1. Attenuators and dummy loads are relatively cheap on Ebay. <br>
<br>
2. Got some RB-58? Make your very own attenuator based on the length
of the coax. I had to drop a broadcast Fm exciter output by 3 to 4
db, and I use 100 feet of RG-58 to do that. <br>

<br>
p.s., I would set the attenuation level based on the regular power
level of the exciter/driver. That way you don't have to worry about
pulling back the power, ever.<br>

<div>I recently picked up an old MMT 1296-144 transverter. This
particular transverter takes a maximum of 300mW input. I am
currently unable to test it since the lowest output on my
radio is 1W. I am looking for tips, equations, etc on how to
design and build an attenuator to both test and, if it works,
eventually use this transverter.</div>
