Standard Horizon vhf stuck at screen message "EE-PROM initializing"
It sounds as if the radio needs to be reprogrammed. It could also be a cold solder joint causing the problem but my guess is the radio needs to be reprogrammed. If you purchased this used, it is very likely that the frequencies were removed prior to the sale. OR, the EEPROM was removed to make surre that the frequencies were removed. It's typical practice for radio shops to do this to prevent unauthorized use on radio frequencies.
Where is the taxi radio wiring taken from the battery or fuse box?
Usually from the battery, but it all depends on the installer. Most of these istalls have been poorly done by people that don't have a clue. ower should be taken directly from the battery with a fuse at the battery terminal. This will reduce electrical noise heard on the radio.
How do I wire a microphone?
More information please. Re wire existing? Hand mic or desk style? It is often cheaper to buy a new one when you look at the time to do it well. Sometimes you can buy a mic cord and re solder the head to it.
It sayes busy all the time standard horizon hx280s vhf
It sounds like you have CTCSS squelch activated and that the manual quelch control is fully open. Try adjusting the manual squelch. My quess is that the "BUSY" indication drops, and you will then be able to scan, etc.
