I am tossing around the idea of building a 6 meter repeater. This will have
to be single site if I do this. What are you guys using for the repeater,
duplexer, and antenna?

I just got a new neighbor at my 6 meter repeater site, a low power (30
watt) FM broadcast station on 94.9MHZ. I now have low level

You might have better luck with shorted coax stubs on the target
frequency with tees to the feeder line and at both ends of the coax.

Joe,
Because the separation (about 45 MHz) is significant, you might consider
installing a cavity filter on your receiver input. A less expensive
solution might be to order up a helical resonator filter from DCI.
Don't forget that the FM station operator has an obligation to not

Hi Folks,
I was just wondering if one of you who has the software to

take on 6 meters. I have two sites 8 miles apart, and vertically
separated by about 30 meters.

Hi Eric/all,
Since this is just a curiosity at this time, let's figure 50 watts,
0.25uV, & 500khz split.
I figured that was the case about the vertical separation, but
threw it in anyway.
One site would be a solar site, so it would make sense to
make it the RX. Guess it might require a notch ca

Well, since we are 1meg splits here -thanks Don-,
that should help some also. (I had looked up a
couple of repeaters around here & saw .5 split,
so thought that's how it was).
Anyhow, it's just in the thinking stages.

thanks for all of the good info.
As the receiver site will be solar (& there's
nothing electrical of any kind for quite a ways),
I guess the site should be pretty quiet.
Now start looking for some hardware.
thanks again!

The FCC rules say you must link on a frequency of 222.15 MHz or above.
That's one GOOD reason not to.
