Description:    Manual download   Simple and practical PC control software, you can export Touchstone (snp) files for various radio design and simulation software through PC software. The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 900MHz. The metal shield is designed to reduce the external interference and improve the measurement accuracy. The 50535-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic. The extended 300M-600MHz band provides better than 60dB of dynamics, and the 600M-900M band is better than 50dB of dynamics.   This is a DIY product that provides perfect vector network measurement capabilities in the size of a credit card. It includes a 2.8-inch touch screen and 500mAh battery, which can be used offline for 2 hours. For longer measurement, please connect external power supply or contact me to make a larger battery version. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring.           Basic performance:   ● PCB: 54mm x 85.5mm x 11mm (without connectors, switches) ● Measurement frequency: 50KHz ~ 300MHz (50KHz -900MHz, enable extended firmware) ● RF output: -13dbm (maximum -9dbm) ● Measurement range: 70dB (50kHz-300MHz), 60dB (300M-600MHz), 50dB (600M-900MHz) enable extended firmware); ● Port SWR: ● Display: 2.8 inch TFT (320 x240) ● USB interface: USB type-C communication mode: CDC (serial) ● Power: USB 5V 120mA, built-in 300mAh or 500mAh battery, maximum charging current 0.8A ● Number of scanning points: 101 (fixed) ● Display Tracking: 4   ●  Marking: 4   ● Setting Save: 5   ● Measuring S parameters, voltage standing wave ratio, phase, delay, Smith chart...     Package list:   1X NanoVNA host (with 500mAh battery)   1X USB Type-C data cable   Le 04-avr.-20 à 14:27:06 Paris, le vendeur a ajouté les informations suivantes:

The Cobra F57 Fixed DSC VHF is a rugged and waterproof all-weather fixed marine VHF. With a clear and easy to use screen and controls. This VHF has a power range from 1 to 25 Watts making it perfect for coastal cruising, use on a RIB or offshore passages. It can be connected to a remote speaker and NMEA output and input for GPS and connection to a chart plotter, using the speaker to amplify alarms. Cobra has added in their rewind and say again function which means the last 20 seconds of an income radio calls are recorded and can be played back. We have found the buttons, even with cold or wet fingers are nice and easy to use and grab. Digital Selective Calling allows you to send a distress signal at the touch of a button or exchange position information with other boats or stations. DSC features on this Class-D radio include A Dedicated Channel 70 (DSC Channel) Receiver GPS Position Display Capability Illuminated Distress Button, scan and memory scan functions as well as dual watch Easy MMSI Entry, 1 OR 25 WATTS Dual output power for short and long communication. REWIND-SAY-AGAIN¨ Replay missed calls. Automatically records the last 20 seconds of incoming radio transmissions. Handy when in noisy conditions. RADIO CHECK Checks battery voltage when transmitting, RF power output, and antenna output. GPS CAPABILITY Plug-and-Play using the new C.P.S. (Cobra Positioning Systems) external GPS. No other connections required. You can send your position information in case of emergency, or exchange position information with other boats. Waterproof  JIS8/IPX8 standards; Submersible for 30 minutes in 1.5 meter deep water. EXTERNAL ALARM INPUT Senses the alarm from your chart plotter and uses the speaker on the radio to amplify the alarm for way point arrival, MOB, etc.

Icom IC-R7100 VHF/UHF receiver in working condition. Covers the 25-2000 MHz range continuously (no apparent gaps) with good sensitivity. Has multiple receive modes, including FM, FMW, AM, AMW, as well as SSB. Excellent for scanning the higher bands without having to individually input frequencies, as you would have to do with most scanners in this range. Operates on 120 VAC, so no external power supply is necessary. Included are a small whip antenna and AC power cord. Backlights work on both meter and display. Buyer pays only actual shipping cost.
