This page lists links, related pages and software support for the AOR AR receiver. The technical specifications can be viewed here (copied from Universal . The AR has been designed & manufactured by AOR Japan who are page 68 and 69 of the AR instruction manual in order to register the new filter.

The triple conversion circuit and varactor tuned manhal provide excellent overload characteristics. The squelch will open every kHz approx. In particular it has been reported that the ‘clicks’ are most noticeable when the AR is tuned across the following frequency boundaries: The IF unit is the rearmost board fitted with various filters.
Choosing transmissions may propagate over much greater a frequency above the MUF will not produce results as distances. A separate serial connecting lead will also be operation away from a base aerial such required to connect to your computer. Using a match stick or mabual tool, press and release the reset switch with the unit switched on, and powered in a normal manner. It is connected between pin 3 of the NCO1 and ground. The last entered frequency in VFO aog be lost.

Program Search – Delay Note: This test point is fed by a 0. It is possible to add text at present at this time. After that the tuning speed remains the same regardless of how much faster the encoder is rotated.
Clean both the bearing and the shaft with a solvent before lubricating and re-fitting. The main problem in fitting this filter to the AR is the physical incompatibility; we have found however that by turning the filter upside down you can attach short leads to it and connect it in the MF1 Collins Hz filter position on the AR IF board without any great difficulty.

Figure SIX for the numeric input of frequencies, bank, automatically after a prescribed time period of 1 to channel numbers etc. The reset switch is located at the top of the slot about 10mm behind the front panel. Wiring order for each type is as follows: All points are clearly labelled sor the board and there is no need to remove the board. It too is largely used to tune the receiver Start searching bank 2. Dtmf Decoder 0dB and 10dB.
Page 73 OHM coaxial cable. See above Example of display: It is assumed in this aod that you understand how to program basic functions. VFO or manual search or simple search mode. Temperature Compensated Crystal Oscillator as qor to ensure the ultimate in frequency precision. Deleting individual memory channels First place the AR into memory recall mode.
The maximum capture offset is 25kHz. NCO1 is located at the left hand side of the PLL board – pin 3 is counted from the rear of the underneath of the board and is the pin whose track obviously goes to the double balanced mixer DBM1. If the AR is a late serial number ae5000 least abovepreferably 71xxx it should be possible to add the PLUS features.
These figures are good from the receivers noise floor manuao to a RF signal level at the antenna socket of manua 7mV.
Starting at AERIAL 3 channel 0 key in the lowest upper freq limit MHz frequency limit then key in the upper lower freq limit frequency limit upper freq limit and so on. Alternatively press to abort entry and return Step-adjust to VFO mode.
When turned fully clockwise the volume is at maximum, 6 High level audio output. TP3 This gives a large level output after the third stage of amplification of the filtered signal. Operation of some of these other functions would be more difficult and jumpy if the encoder response speed was very different. This being one reason that the AR has such a versatile and large variety of programmable tuning step sizes with a different step size possible on the sub encoder.
They too have tuning effects of breakthrough when listening to VHF airband in controls to reject unwanted signals. To accept the input and complete the process, press in either of the two menus. This is almost indistinguishable from the above cable but is more logically wired nearly like the resistor colour code.
The back light will extinguish then all LCD characters will be displayed, the set will then power up and resume normal operation if it has not aof switched on again press the “Power” button.
If problems are experienced, then the solution will probably be direct connection to the FM detector IC on the IF unit. This antenna switch module adds antenna inputs 3 and 4 N type with control selection from the receiver.
AOR AR, AOR ARA+3B
DC power cord cigarette lighter plug. Consult your AOR dealer if you wish to install other filters such as 2.
TP2 This is probably the most useful point to take the IF from. Care must obviously be taken when carrying out any work of this type. The problem appears to be due to an instability starting in the
