Guerrilla Repeater

Would it be possible to make a birdbox style housing for it, and then forego the need for an external arial? So fit the solar panel on the roof, then just carefully play with everything else to have it inside the 'house'

If you drilled lots of holes, upward facing at 45 degrees, would that allow the signal, but not water, inside? Does that make sense?

Is it legal LS, to use the 2x UV5R repeater system on business channels i have a licence for?

for evaluation purposes i could set up 2x UHF rx on 449.3125 and tx on 449.4750?

let me know what you think from a legal point of view.

its also worth mentioning we are the only business on these freqs in th area i am aware of.

Yep, do-able scythe

I'd try and find a thin plastic wood ( and non absorbant) to make it from.

To be pedantic try cooking some of said wod in a microwave. It it does not heat up it is non conductive and will be fine. It it gets warm / hot you'll either have to have external antenna or seek out an alternative material.

Hi Binnie,

I'm not au-fait with the Private business license regulations.

You'll need to check out the small print for yourself.

the grey area that I'm trying to get resolved with Ofcom in the CB regulations is that it allows to record and play-back of transmitted signals. It also has the requirement that Receive RX and Transmit TX are always on the same frequency. This apparently implies that a Parrot repeater, receiving and then re-transmitting on the same frequency, is compliant with the regulations...... but to date Ofcom have not confirmed this.

I strongly suggest that you get an Ofcom agreement before proceeding as you could jeopardise your business license if you get it wrong.

Thanks LS.

My other option is to set up a clandestine repeater somewhere rural thats not going to interfere with anything and use PMR freqs on 1W (yes naughty, but not risking business licence!)

also i see you get repeater boxes from ebay, about £50 and records up to 120secs of audio, then TX back on same freq,

dunno if they are any use though

Yep, a radio tone simplex ( parrot) will cost you less than £60

Hook that up to a PMR which is CTCSS/ DCS enabled, put these into an RF transparent waterproof enclosure, and you'll have a low cost and discreet test bed.
