RE: Field Charger
You would need to buy or make the leads to connect the charger to the TX and RX.
Peak deteting chargers occasionally have a probem with the diode in the transmitter's charging circuit. (false indication of full charge, or failure to detect the peak at all) Some people say to bridge the diode (which can void the radio warrantee.) Better is to just pull the battery out of the radio when fast charging. With the battery out of the case it will stay cooler anyway. Since overheating a NiCd can make it explode... the last place you want to get it hot is inside the transmitter.
