[Repeater-Builder] Kenwood TK 730 as a repeater

2008-01-19 Thread k0jxi
Wonder if I could get some quick comments on the feasibility of using
two Kenwood TK 730 mobiles as a  2 meter repeater.  Not sure if KW 
actually has has that configuation as a product.  I realize that low 
power would have to be used..  I have a friend in a old club I 
used to belong to ask met the question and I am not familiar with the 
radio..  I have built several repeaters out of Exect two with good 
results.  I would be worried about the receiver front end and over all 
selectivity for 600 kc spacing.

Any thought would be appreciated.

Thanks Dale K0Jxi

Dale,

 

The 730 is a very nice and narrow front-end radio with big helical to tune.
It will work better than you think. If you are playing around with the low
power model 35wt radio. You will want to run it no more than 10wt and add a
24v fan to cool the heat sink. We have used the 35wt UHF in some IFB
configurations for years and they have been keyed down for a sum of 10+
years and have never gave any sins of weakness. I know they are not designed
for continious operation but they built a very good radio. The newer
version, the TK-790 is a much better radio if you can find one. 

 

When I first got into radio back in the 90s. the company I first worked for
had a 3ch UHF LTR system built out of the low power units turned down to
10wt and then into an amp.
