开云体育Hi Matt, ? I believe that the 818 is almost identical to the 817 in operation with just a few enhancements. So here are my comments. ? The power indication flashing or not flashing when in the high power mode is purely dependant on the voltage being fed to the radio from whatever source. You could test this by powering it from an external variable supply starting at 12V and then gradually reducing the voltage and you’ll find that at a certain point the icon will start flashing. The rationale is that when using an external supply of around 12V the display doesn’t flash but when using the battery, which normally has a nominal voltage of about 10.2 V (NiMH) the icon will flash to warn you that you are on high power and hence will run down the battery much faster. ? Regarding the S and SW indications, it will read S on receive indicating that you are reading signal strength and SW on transmit indicting that you are reading SWR. If you had it set to Power, then it would read P instead of SW on transmit. Obviously, the less bars shown in SWR, the better. ? 73….Eric VK2VE. ?

I off-loaded the Windcamp battery and went out with the Bioenno 12v/3Ah for a SOTA activation. Indeed the power symbology did change with the external battery to show the full 6W (blank display) and all the subsequent settings. Through some reading on previous posts WRT the battery drain on the 818/817, I believe this is completely negated by using the off switch on the Windcamp battery cover which preserves the battery. Correct? |
