1  Is the rt21 compatible with h777? My coworkers have the h777s but I want the rt21.

2  Salve, ho acquistato retevis h-777 , vorrei sapere le frequenze al quale viene impostata la radio di fabbrica sui diversi canali, se potente inviarmi un elenco. Potente indicarmi se è presente un canale utilizzabile liberamente in Italia ? Grazie Luca

3  Hi, I have 3 questions Context We run a hunting business in South Africa on a 10 000ha property (Approx. 13km long x 7km wide). We have 15 x H-777 radios and will be purchasing another 5 (Total 15 x Radio's). Problems: Due to the size of the property + obstructions like hills etc. I would like to relay the comms. from the top of 2 hills to cover the full extent of the property. Q1 - How do I extend the coverage on the property? Repeaters x 2? Power source on top hill (Solar Panel + Battery type)? Antenna's? (What does the product term "Gain" mean? Adapters & cables? Context At the moment we use Channel 1 for All Stations, Channel 2 for Staff, Channel 3 for Hunters. Will the repeater relay the message from 1specific channel via repeater to all other channels? ... or only to Channel 1 on the other radio's? Q2 - I'd like a fixed radio + cable + roof antenna for the Main House and Hunting Lodge. These houses are at bottom of valley +-2.5km away from each other.

4  Is there a way to get the radio to beep when you press the transmit button and when you receive call?

8  I just got 6 of these H-777 radios can I leave then on the charger is not needed for a period of time? Or should I do a complete charge then place a outlet timer on them so they come on every 2 or 3 days and turn on for like 4 hours and then turn off. and repeat every other week. Or fully charge the batteries and use the same charger to only turn on Every Sunday for 4 hours. I want to keep the batteries in good shape for as long as I can without hurting the batteries. If leaving them on the charger all the time is the best Let me now. If using a wall timer and have then turn on every 2-3 day a week is best please let me know.

10  I need the all the channel frequencies on the Retevis Rt-81 so I can program my mobile radios to it. Thank you.
