| Przemiennik D-STAR Tak mógłby wyglądać nasz przemiennik. |
| Małe uzupełnienie, zainteresowani chyba się połapią: I've started on my stand alone 2m DV repeater. I'm using two Icom IC-F121S radios which I have successfully used to repeat a DV signal with a back to back setup. I found it best to program each channel in FM narrow mode. The radios are mounted to a 2ru shelf and I have started on making holes in a die-cast aluminum box to house the DV Adapter PCB. To power the DV Adapater when it's away from a PC USB connection, I've built up a small 9-18V to 5V adapter using a small switch-mode converter. The TX radio will run VERY hot on 50W, I'm going to use a small horizontal cage blower to keep lots of air circulating over the heatsink of the TX radio, hopefully this will help keep things cool on the transmit side of the repeater. |
