Here is a replacement modulation meter for a Belar FMM-1 FM Modulation Monitor. The Belar part number for this meter is#1120-0002. This meter was removed from an extender panel. Meter indicates 0- 133% modulation on the top scale and 0- +2DB on the bottom scale. The mounting brackets are included. Meter was tested and works and the movement is smooth. This IS NOT a true VU meter. It is a 400uA full scale DC meter. It was tested using a variable power supply. If you apply an audio signal nothing will happen. It will only work with a 0- 400uA signal which is what the FMM-1 will supply. I also have a working Frequency Meter for the FMM-1 in another auction. If you buy both I will ship them together.

MARCONI 2305 RF RADIO PMR FM BROADCAST MODULATION POWER DEVIATION MONITOR METER
Marconi 2305 Modulation monitor. Purchased a few years back but seldom used and surplus to requirements.In fairly good condition with minor marks on the top panel. Any questions. Feel free to ask. Collection from Stockport, Cheshire welcome. Below is the manufacturers spec: 1. 2305 is a high performance. Microprocessor controlled, modulation meter with a comprehensive specification covering the carrier frequency range 500 kHz to 2 GHz. 2. Operation may be either local or remote. Local control is obtained via functionally grouped key switches which form the front panel controls and which direct all the instrument functions except those of SUPPLY ON and LF LEVEL. 3. Indication of measured quantities is provided by two l.c.d. 7-segment digital displays: frequency- either of the carrier or of the modulating tone- appears in the 8-digit left-hand ... moredisplay. Modulation- in% a.m. kHz or radians deviation- appears in the 4 digit right-hand display. 4. The microprocessor allows maximum flexibility in arranging and controlling the circuit functions and permits remote operation via the GPIB* when the instrument is fitted with the GPIB interface optional accessory. The 2305 is thus as well suited for stand-alone manual operation as for incorporation in automatic systems with programmed operation and makes few demands on operator skill. 5. In its simplest method of operation. The 2305 provides both automatic tuning and control of the ranging circuits, although tuning may be controlled directly by keypad entry of numerical data. And individual ranges may be retained by the use of keyboard second functions if necessary. A HOLD ON/OFF key permits all ranges and functions to be locked in their present states. 6. In both forms of tuning. The local oscillator frequency retains the same sense relationship with signal frequency needed to ensure that positive frequency and phase excursions are always presented as P+. 7. In the CARRIER ERROR mode the instrument will measure small frequency drifts or offsets by continuously subtra
