![]() In reception terms, the earth is not wildly important. Any analogue or digital image modes within the appropriate bandwidth, e.g. more likely you will get a signal that way, which will suggest that work is needed on the normal aerial.Ĭommon probs are water in the coax sheath, and an odd stray barely visible bit of sheathing bridging the coax and shorting it out. Any digital mode within the appropriate bandwidth, e.g. If there is still nothing on the radio, then best to have it checked out. a simple multistrand insulated copped wire hoisted up on a halliard, and attached to the radio will do. If you still receive nothing, then try an alternative aerial. ![]() The standard press RTTY parameters are 50 Baud with 425 Hz shift, but will vary. the point being that weak signals can easily be swamped by electronic noise from your fridge, or a nearby generator etc. Frequencies shown are tone/mark centre frequencies for receivers in FSK mode. the broadcast stations put out an altogether stronger signal - you can easily have a broadcast station 1000times stronger than a strong amateur station.įirst thing to do is to put yourself in the situation where reception chance is best ie some relatively isolated anchorage with everything in the boat switched off. It may be the radio, but the fact that you can receive broadcast stations suggests that the aerial is a more likely culprit.
