Bucket Cross-Band Repeater

A cross-band repeater in a bucket project:
"The “Bucket Repeater” is a battery powered cross-band VHF/UHF repeater in a weather proof enclosure that can operate unattended for a week or more, and be remotely activated or deactivated from miles away as needed."

He uses a Puxing PX-UV973 for the radio and has a complete parts list.

Puxing PX-UV973: Full Review

John has his full review here. Highlights for me:
"The radio can be set to use both display lines for a single channel. You could use one line to display the channel name, and the other line the frequency and such. When scanning, however, it reverts back to use of both lines of the display. I wonder why they did that. 
The cross band repeater works great. you program one frequency in the upper display, and another in the lower display. If a signal is received on one of these frequencies, the signal is simultaneously retransmitted on the other frequency! One frequency must be VHF and the other UHF. I am unsure if the radio is programmed to disallow same band repeating. The manual cautions against it... so be careful if you set it up wrong. 
The radio has a true dual receiver. You can select the volume levels via the menus and software to differentiate which VFO is louder than the other. 
I didn't test the full duplex option, as I didn't have a satellite pass handy to test. Also, there are no linked VHF/UHF repeaters in my area."
"Volume in all cases can be loud enough in most cases without distortion. BUT, if a signal is not full quieting, it seems the noise in the signal is enhanced if the received signal is very weak. You could receive a faint signal, but only hear noise."
"What I did not like: The battery life could be better; but this can be fixed by getting a more powerful battery. 
The scan speed is terribly slow! If the dual watch function is disabled and the radio operating in single channel mode the scan speed does improve a but; but is still slow. 
This radio does not have a compander, so narrow band fidelity may be lacking. This radio does include a scrambler, which is really more or less something that would be used far less than a compander. 
The annoying amplification of noise is not a deal breaker by any means; but is a real pain at times."
 Overall, he likes it for the features and despite the shortcoming mentioned above.

Puxing PX-UV973

John, KD8DVR, is taking a look at the Puxing PX-UV973. He's excited as it will do cross-band repeat. The specs are here and his first thoughts are here.

You can get one on eBay for $92.

And there is a Yahoo Group.
