What we really need in a transformer is 18 V c-t. This voltage is perfect for both the +5-volt and + 13.6- volt supplies. Those of you who have tried were frus- trated, I’m sure, by the at- tempt. Along with the idea of the petition, it seemed important to have as many hams as possible attend the hearing. A large turn- out supporting our position would be persuasive. For three Amperes at the load, two will flow through the pass transistor and one through the LM309K. If you use a germanium pass transistor, you can omit D2, as D2 compensates for the base-to-emitter \unc- tion voltage drop of the pass transistor. Improving the Transmit Audio Being in the professional audio business, I tend to be a bit «picky» about the audio we, as amateur radio operators, hear.


The distance wasn’t amazing, but my ability to shoulder my way through a medium pileup was impressive. No sooner was \ finished talking with Guy than I tuned up a few kHz and heard VP8RX in the Falkland Islands trying to con- Who is this mysterious and handsome stranger? This is about as sim- ple as it could be. As far as drift goes, we have found that it is at a vefry slow rate, completely due to changes in outside temperature. A TV set is a very broad receiver and will tolerate considerable dirft. After a few trials, I have discovered that this has to stop at around 50 cycles. The loops used had distinct directional characteristics- A loop had variation coverage as much as five to one for- ward compared to the sides. Global connectivity With incredible network support and integrated dual SIM support, the Huawei Mate 9 offers outstanding performance worldwide.

Remove the 901 ‘s bottom cover and locate the socket for board PB1703, Connect a 68k r Vi-Watt resistor between the ground and pin 16 of this socket, then bypass the resistor with a 2.2-uF tan- talum capacitor. The tuning range of the LO is enough so that both the signal that we want and its image can be tuned in. Transient load changes may generate out- put voltage variations amounting to ±20 per- cent or more. As you might gather, l don’t recommend this circuit for the ham shack.
