[11:18] they'd have to custom make them [11:19] yes, they make custom for me too [11:19] all the radios i bought are custom [11:19] anyway, we have a digipeater planned using one of their tunable transceiver modules [11:19] you can buy a 145.175mhz NRX1 and it wont be more than 50e [11:19] with transfer cost [11:19] jeez [11:20] scrre that [11:20] screw* [11:20] lol [11:20] seriously [11:20] man, we have crisis! [11:20] we paid AUD$60 for the 145.175 300mw transmit modules [11:20] yes 300mw its expensive [11:20] what i'd be doing is buying a cheap $40 chinese 2m handheld radio, and using that [11:20] 1W or 5W transceiver [11:20] done [11:21] cool [11:21] anyway [11:21] I got a nice 2w handheld on fleabay darkside [11:21] 40quid [11:21] mm [11:22] would prolly work nicely, quite small to.
