1、Modifications for the ALINCO created 28-03-2002 from www.mods.dk (ALR-206) Undocumentated function of the Alinco ALR-206T English language (ALR-22)Extended frequency RX/TX of the ALR22T BP2 is located right above it, hidden. The jumper is a blue wire. Hit “All reset“. Then TX frequency will be 130.0
2、0MHz - 173.995MHz. This is the second step. If you modify all steps, frequency range will be: RX 108-142.995MHz TX dies ist der Spiegelfrequenzbereich des 70 cm- Bandes! Dementsprechend unempfindlich ist dort auch der Empfnger: ca. 60 dB schlechter als im AFu-Band! 2. 400 MHz bis 469.995 MHz hier ra
3、stet die PLL bei RX im gesamten Bereich; bei TX ergibt sich ein Bereich von ca. 415 MHz bis 465 MHz; 3. 810 MHz bis 909.995 MHz hier rastet die PLL nie! Also fr alle BesitzerInnen, die gern mit ihrem Handy rumexperimentierem - hier noch einmal die Tastenfolge: 1. Funktionstaste gedrckt halten und zw
4、eimal die B-Taste drcken - Funktionstaste weiterhin gedrckt halten und die Ziffernkombination 2 - 1 - 2 drcken! Im Display erscheint “open“ bzw. “close“ und es ertnt eine Melodie. 2. Im “open“-Modus kann im VCO-Betrieb ber die B-Taste der gewnschte Frequenzbereich eingestellt werden. Vielleicht gibt
5、 es ja noch weitere Tastenfolgen, die weitere nie bentigte Funktionen freigeben, hi! bis demnchst, 73 de Ulrich aus Wolfenbttel!

All standard disclaimers apply.
13、 This mod is for the DJ-S41T, and not the DJ-S41(C) 10 mW version. 1. Place the radio face down on a soft towel. This avoids scratching the display and gives you a place to put the seven tiny screws to be removed. 2. Remove the batteries. 3. Remove the three screws on the upper rear cover, and the f
14、our screws inside the battery compartment. The rear cover can be lifted and removed easily, as there are no wires to be concerned about. The antenna connection is made by means of a gold-plated spring contact. 4. Look for a small (about 1 mm) green surface mount resistor (actually a 0 ohm jumper), l
15、ocated on the far left side of the exposed circuit board, located to the “northwest“ of the speaker. There is a marking in white letters, OP/CL, this resistor is over the top of the “P“. It is the only green component visible on the board. (This radio does not have the traditional Alinco red and blu
16、e wires which have become so familiar.) 5. Carefully remove this resistor, using a small tip soldering iron, tweezers and a steady hand. 6. Re-assemble the radio, being careful that the thin rubber gasket is seated around the inside edge of the rear cover. Replace the batteries, press and hold the “
17、F“ button on the left side of the radio, and turn it on. The display should show all segments and markings. Release the “F“ button and the radio will now be capable of operating from approximately 425 MHz to above 470 MHz, depending on the VCOs tuning. The display will blink if the VCO is taken out
18、of its range. Re-tweeking of the VCO is not recommended. THE NOT-SO-FINE PRINT: 7. Although reception on the expanded frequencies is legal, transmission is not. This unit is not FCC type-accepted for anything but ham band (425 - 440.995 MHz) operation. KB1MZ 28-May-1997 This modification is read 184

Freset MONI / Lophv squelchLs while in tone-select mode, F-Tone toggles tone on or off, T appears on the LCD when on. PTT to exit. Held, Down will initiate a scan, like SCAN only downard. Modes: In most modes, Up and Do
34、wn select whatever parameter PTT will save. PTT+DOWN: Pressing up or down while transmitting with PTT will SEND either a 1750Hz tone or a rising sweep tone (depending on the mode setting) as a call. On-DOWN turns the “stand-by beep“ or courtesy tone off. Up/Step The up button increments the frequenc
35、y by the current increment, which is set by F-Steps mode, in which Up/Down adjust the step; 25kHz, 50k, 100k as 10, 150k (as 15), 200k (as 20). Note that the displayed step sizes are not intuitive. Traditionally, 2520 but “20“ is the biggest step and “25“ is the smallest. Held, Up will initiate an u
36、pward scan, same as SCAN, except taking longer. Modes: In most modes, Up and Down select whatever parameter PTT will save. Tapped during Scan, will stop it on current freq (VFO or memory). PTT+UP: Pressing up or down while transmitting with PTT will SEND either a 1750 tone or a rising sweep tone as
37、a call. On-UP turns the “stand-by beep“ or courtesy tone On. The unit will can send courtesy tones, possibly useful when simplex or if the repeater doesnt but you want to. Probably rude when on a repeater that has courtesy tones already, as it makes you sound like a linked repeater system. “V/M“/MW
38、Toggles between using the single VFO and the 21 Memory channels. F-MW starts memory-write mode from the current VFO setting or the current memory slot; use the Up/down buttons to pick which memory to write to (Memory number blinks), and finish with unshifted V/M/MW. Use F-MW while in MW-mode to eras
39、e the memory channel selected (blinking). (I guess you could use a PTT to cancel MW mode.) Writing from a memory slot to itself is how you save temporary changes (eg adjustments to shift or tone) which would otherwise be reset to their old values if you changed channels and came back. On-V/M toggles
40、 the unit into/out-of the mode used on the non-programmable business band model: fixed channellized by channel number, you only see the channel numbers. Not terribly useful for hams, who ought to know their frequency. PTT Push To Talk. Does what you expect most of the time, push it and you talk. It
41、will display the xmit frequency if its legal, or OFF if its offset out of band. PTT exits many of the modes. PTT enables SHIFT to toggle LOW power (50mW or +17dBm)/regular (340mW / +24dBm). There is no documented F-PTT or On-PTT function. Moni/L Monitor bypasses the squelch, so you can hear anything
42、 down in the noise. This is used for the mandator listen-before-talk as specified in Part-97 and ARRL good operating practices. Its in a very handy location for its intended use, even thought at 350mW, whom I gonna win a double with? I guess with a IC-4AT a few miles further out. (Since the TONE doe
43、snt do tone decode, this is just bypassing the pre-set carrier/ signal squelch.) Tapping Shift while hodling MONItor will switch you to listening to the transmit side of the repeater (or back), the “reverse“ monitor, when transmit shift is in use. Function The Function button, while pushed, enables
44、the non-bolded versions of the keys. F introduces many of the modes, modifying other keys. Tapped quickly by itself, F enables changing the MHz with Up/Down, which it denotes by blinking the digit in question: 448.1750. Tap a second time, it moves to the 100KHz: 448.1750 and a third time to exit the
45、 mode, but it will time out quickly to normal (only mode that does?). This is not usable in MEMORY mode, only in VFO. It is also usable in SHIFT to change MHz, in case you need to go from 5MHz offset to 1 or 10MHz in your local bandplan. I havent tried it in TONE, maybe it would let you do tones qui
46、cker? I doubt it. Mic Talk here. speaker Listen here. display LCD display, has memory channel #, frequency is displayed like 449.9250. The .25/.50/.75 are stacked as literal items on the LCD, not formed from segments, so the .75 looks like a superscript and the .25 like a subscript and the .50 like
47、a whithered arm, but it actually reads better than this sounds, since theyre nice crisp numbers, and it gives a feel of how high it moved. Has indicators + - for active offset, T for Tone active, LOW for low-power setting, APO for AutoPowerOff active, a Bell for Alarm set (blinking if triggered). an
48、tenna There is no BNC or SMA connector to attach a gain antenna to. It comes with a fold-down rubber duckie that might be 0dBi if youre lucky. Im wondering if a passive-re-radiator on/out the window (such as are sold for use with 300mW pocket cellphones, but re- engineered twice the size) would help
49、 when using it in a car that isnt mounting a “real“ 440 rig. Modes Modes are described under the key that initiates them. Some modes are transient programming modes, usually exited by PTT. Some Modes are global settings toggled on and off. Many modessome keys uses in modes are cross referenced.) Just about each F-button combo either enters programming mode or toggles a global mode. Turning the unit On with most any button depressed also affects some mode; some toggle, some others
