Last summer the sailing publication, Southwinds, started a free ad service for finding crew, or for crew looking for boats. Unfortunately, I only found out about it in November, when I was a week away from departure time when I placed an ad looking for crew.

On a recent cruise up the Hudson and along the Erie Canal, I was rarely out of contact for more than a half hour at a time. I use a directional cantenna antenna that gives me about a 1/3 mile range using 802.11b.

Denote S(t) as the digital baseband signal and fc as the carrier frequency specified in GNU Radio, are the output signals at Tx-A and Tx-B ports Re{S(t)}*cos(2*pi*fc*t) and Im{S(t)}*sin(2*pi*fc*t), respectively? If not, what is the output signals at those two antenna ports? > > Thank you in advance!

I finally found a household refrigerator that will dimensionally replace the current 23 year old Whirlpool refrigerator on my boat. The new model is a new model Kenmore and according to the specs is Frost Free. I was pleased at first but then I started thinking about the frost free cycle heaters coming when the power is being supplied by the inverter.

I totally forgot that. Then it's somewhere in the range of 0.2uA (modern RTC's with NVRAM) to 10uA (really old ones). RTCs do not use that much current as one might think. I "recently" did a MSP430FR5736 based system that had its RTC running and was powered by two SR48 coin cells (~80mAh). Total expected lifetime was 1.5y with all the stuff it had to do.

Hello, This might be a common effect but I don't comprehend why it happens and if it is avoidable. I'm using a N210+CBX to transmit a 10 MSPS OFDM signal, with Fc = 1.5 GHz. When transmitting, I can see some kind of "replicas" at +-7.5 MHz from Fc, always with a 40 dBc difference.

I measure the power of the desired signal x(t) = r*exp(j*2*pi*(fc+f)*t), and the undesired replica x'(t) = r'*exp(j*2*pi*(fc-f)*t), putting a spectrum analyzer marker on each peak, and see what the delta is. I tried running free without calibration script and the result was worse.

I am hoping they will, I have the garmin bluecharts for the areas I want, with my chartplotter and backup handhelp GPSmap. These are for a backup. Hopefully, they will work with one of the free navigation programs. I have also downloaded the ENC charts, but haven't actually done anything with them yet either.
