Hi Allen,
Yes, It's hard pleasing everyone :-) Yes the repeater is based on Vertex
product. Easy for us to do as we distribute for New Zealand and have the
Engineering support from Japan.
Interestingly enough it was the internal battery that dictated the
specifications of our PRU, which is an 18Ah SLA, hence the weight and form
factor. We could have gone to smaller batteries but at the expense of talk
time, so another compromise. Radios and Duplexer are relatively minimal, but
everything still is a tight squeeze. We supply an end fed 1/2 wave that goes
with the kits, this is terminated via an N connector, giving the user access to
other aerials if necessary.
Nothing beats a good project like a PRU
Regards
Gareth Bennett

Gareth,
I like your portable repeater! Is it Yeasu/Vertex based? I agree that an RSSI
controlled repeater could be problematic for outlying areas, so if it was
implemented, we would want to take careful steps to make sure it was
appropriate. My thinking was that the relatively small footprint served by a
portable repeater with marginal antennas and low power output might militate
towards limiting the power. Of course, any low power units trying to hit the
repeater would tend to make it vote towards higher power output, so maybe the
wisest course would be to just set a fixed power, or offer the repeater owner
remote power level control. I am trying to make a unit significantly smaller
and lighter than your 22 pound machine, so power savings is going to be an
issue!
