"thuss" wrote in message oups.com... HF transmitters are very common on boats and only draw a lot of power when transmitting and even then it's not enough to noticably discharge a normal house battery bank. True on voice SSB. Digital modes pretty much are like AM. They draw max power the entire time the transmitter is keyed. Last time we sailed from California to Hawaii we used the HAM/SSB nightly to talk on the PacSea net, Not much power since SSB draws power on the peaks only. get weather fax, RX for fax is pretty low power anyway. and do phone patches. Same as any voice mode. Low overall power. Even with our lowly 12V 450amp house battery bank I never really noticed needing to recharge more frequently than every third day, which is about how often I would charge the batteries when sitting at anchor. Sounds about right. Even using the digital modes, the amount of time one is on the air is pretty small. Unless one is ragchewing for hours on end a marine SSB or ham on board is not a heavy hitter. -Todd -- http://boatblogger/page/thuss http://www.marinewireless.us Falky foo wrote: Problem is powering a HF transmitter with enough wattage without draining your batteries. wrote in message ... I have a general class ham license but have been out of it a LONG time I want to get back into some form of free ham radio comms that would allow me to stay in touch with people while living in an RV or boat So.... I want something small and compact. And Im not sure what "mode" of communications I want. I may want some form of digital comms like packet or pactor.... not sure Any advice on all this? What to get equip wise? What modes to get into? |
