Tuning SINGLE SIDE BAND station with Zenith Royal 7000-1 Radio

How to tune in a side-band station using on a 1970 Zenith Royal-7000-1 Solid State Trans-Oceanic Portable shortwave radio. ———————————————————————- SINGLE SIDE BAND RECEPTION Single Side Band transmission, a recent development in the communications industry, provides a more efficient use of radio frequencies. Receivers designed for reception on the standard AM bands would reproduce SSB signals as a distorted sound, however, this Trans-Oceanic can be used to receive clear and understandable SSB messages in the Following manner: * With the BANDWIDTH in the NORMAL position, turn the radio ON and tune in channel as you would any AM band station. * Tune in and adjust the TUNING CONTROL to the center of the distorted sound. (This should be the point of maximum audio output as well as maximum deflection on the TUNING METRE.) * Turn MANUAL GAIN CONTROL to ON (clockwise). * Advance the VOLUME CONTROL near maximum. * Turn BFO Control ON (clockwise) and set to the center of its rotation. * Adjust MANUAL GAIN to desired volume (instead of VOLUME knob). * While receiving SSB it is recommended that the VOLUME CONTROL be kept near maximum and that the level adjustments be made with the GAIN CONTROL (as mentioned previously). * Adjust the BFO Control for an intelligible sounding signal, then for a more natural tone. * When correctly adjusted, rotate of the BFO Control toward the center of its rotation will cause the pitch of the voice to …

This Is Ham Radio

Vintage ARRL ham radio movie. Converted from 16mm film to video tape many years ago, and now from that ancient VHS to digital. Enjoy the flickering screen, and especially the funky organ music backgrounds! heavy focus on morse code, which of course is no longer a requirement.

Ham Radio 10 meter band is wide open to many Countries around the world. This is the best it has been for many years. It’s a great time to get your amateur radio license if you don’t have it, and a great time to once again try the 10 meter band. It’s smokin! You only need a Technician class license to talk on 10 meters. A great entry level, then you can upgrade from there if you desire.

POCSAG base station prototype on 144.975 MHz

Standalone prototype of a POCSAG base station: Linksys NSLU2 computer on the right, Debian Linux installed on the 512M USB memory stick, cheap USB hub and USB serial adapters from DealExtreme, connected to the Internet using a Siemens GPRS module (on top of Motorola radio, flat-rate multi-SIM data). Dials up automatically when powered on and redials the connection if it drops. POCSAG modem in the top right corner, Atmel microcontroller, original design by N2RVQ. Motorola GM340 transceiver transmitting on 144.975 MHz. ATI Wireless Corporate programmable pager receiving the paging messages and saying “beep”. There’s another receiver (FT-7800) on the background monitoring the 512 bps (yes, bits per second) transmissions. The tiny computer runs a transmitter client, which polls a pair of central servers for new messages which should be transmitted. Another server runs a DX cluster client which uploads DX spots using an HTTP JSON API to the servers. The servers authenticates both the transmitter clients and the message sources using HMAC-SHA1. oh7lzb.blogspot.com

I receive many questions about the arrow antenna and tripod mounting used in my AO-51 video. This video covers, what the arrow antenna is, where to buy it, and how it mounts to the tripod. I show show how easily the antenna is assembled. I forgot to mention, the antenna got its name from using arrows as the elements. Please click on the rating stars below the picture.
