MFJ HF/VHF SWR Analyzer MFJ-259, Ten Tec Model 705 Microphone And More!

The MFJ-259 SWR Analyzer is an easy to operate, versatile test instrument for analyzing nearly any 50 ohm RF system on frequencies between 1.8 and 170 MHz. In addition the MFJ-259 can be used as a signal source and as a accurate frequency counter. It combines four basic circuits; a wide range oscillator, a frequency counter, a 50 ohm RF bridge, and a calibrated bridge unbalanced indicator. This combination of circuits allows measurement of the SWR (referenced to the 50 ohm) of any load connected to the antenna connector.

The TEN-TEC Model 705 is an Electric desk microphone designed for use as a station microphone in commercial and amateur radio communications and in public address and paging installations. This model incorperates a momentary type Push-To-Talk (PTT) button and a Push- ON, Push- Off locking type button, electronic circuitry to switch the microphone on a signal amplifier that adds 13 dB of gain to the output level, an attached output cable and a battery compartment for a 9-volt alkaline battery. The PTT circuitry allows switching transmitters and or transceivers, that have low voltage positive T/R lines, into the transmit mode. A light-emitting diode in the base signals the transmit mode.

MFJ RX Noise Bridge is used to determine the value of an unknown impandance. It quickly adjust almost any antenna for maximum performance, 1 to 100 MHz. Lengthen or shorten your antenna for minimum SWR. Measure resonant frequency, feedpoint resistance and reactance. Works with any receiver or transceiver. Hand-calibrated resistance scale, expanded capacitance range and exclusive built-in range extender.


With the MFJ-1272MX and 1272BX You won't have to unplug the microphone and plug in your TNC every time you want to work packet or other data modes. Just plug this pre-wired cable switch box into your rig's microphone connector and into your TNC and you're ready-to-go -- no more hunting for hard-to-find connectors and wiring up complicated cables
