ESP-12E WiFi Module

Wi-Fi Modem circuit can be turned off and CPU suspended to save power according to the 802.11 standard (U-APSD). E.g. in DTIM3, to maintain a sleep 300ms-wake 3ms cycle to receive AP’s Beacon packages, the current is about 0.9mA. Deep-Sleep does not require Wi-Fi connection to be maintained. For application with long time lags between data

Z-100 Automatic Antenna Tuner - LDG Electronics

(e.g., ladder line), an external balun is required. The LDG RBA-1:1 balun will work with short random wires and the RBA-1 4:1 balun is suited for longer wires. Connect the HF antenna jack on your transmitter or transceiver to the Transmitter jack on the back of your Z-100 tuner using a coax jumper with standard PL-259 plugs.

160m/80m Broadband Antenna by K5GP

For the antenna layout below, the center capacitor is 15 pF at element 3 between elements 2 and 4 and a 4:1 balun feeds the antenna between elements 1 and 2. The SWR is less than 1.7 to 1 across the entire 80 meter band. How do we get back the 160 meter resonance? By placing a series L and C across the 15 pF capacitor. When we do this, we must
