Actually, the problem is with viruses, not the speed of the modem. Many viruses are spread as an attachment. Therefore, no attachments. Glen, K9STH Website: http://k9sth.com Are there still security

You can print the labels on a single sheet overhead transparency. Then use one of the adhesives that come in spray cans. It does take some "trial and error" using a graphics program to get the placem

Back in the late 1960s some of the technicians at the Collins Radio plant here in Richardson, Texas, were testing one of the military amplifiers, 308-U20, that put out at least 20 kW. This particular

The voltage that most of the major electric companies now target is 125 volts +/- 2 volts. Voltages on the "+" side are very common during the warmer months when there is generally a heavier load due

Motorola may have built such an amplifier for the military. However, for the commercial FM two-way market the Motorola lowband and highband amplifiers used 8650A tubes which are the conduction cooled

Those amplifiers used 2 of the 8560A which is basically a conduction cooled 4CX250B. The lowband versions were rated at 330 watts output and the highband versions were rated usually at 250 watts outp

The tubes are definitely not triodes! The 8560A is basically a 4CX250B that is conduction cooled rather than forced air. Glen, K9STH Website: http://k9sth.com ________________________________________

Both the HR-2510 and HR-2600 Uniden can be "opened" by cutting a trace on the circuit board and inserting a resistor. This changes the coverage from 28.000 MHz to 29.6999 MHz to 26.0 MHz to 29.6999 M
