Salve a tutti, giocherellando un po' con le funzioni di questo trasmettitore, ne ho scoperta una senza dubbio originale e carina anche se, come spesso accade per questi piccoli "mostri" di tecnologia, di poca utilita'. Passo quindi a descrivere il tutto.. Premendo il tasto "CALL" e accendendo contemporaneamente l'rtx, si abilita questa stranezza che inizia a funzionare dopo alcuni secondi e che fa fare alcuni giochettini agli indicatori Smeter sull'rtx oltre alla scrittura di due piccole frasi..Probabilmente, la funzione e' stata inserita per far pubblicita' all'rtx esposto sulla vetrina di qualche negozio..C'e' da dire che cio' non pregiudica assolutamente il funzionamento dell'rtx che in qualsiasi momento da' accesso prioritario alle funzioni impostate dall'operatore.. Per disattivare la funzione da me ribattezzata "pubblicita'" e' necessario fare il reset del vfo che si ottiene premendo il tasto "VFO/M>V" mentre si accende l'rtx..Attenzione a non fare l'altro tipo di reset (quello della memoria) che causerebbe la perdita di tutti i dati irreparabilmente.. NOTA IMPORTANTE!!!! Questo messaggio vuole solo suggerire una curiosita' da me trovata sul mio rtx e non sperimentata su altri modelli analoghi:di conseguenza, declino ogni responsabilita' per cio' che potrebbe eventualmente accadere nel tentare di attivare tale funzione. Se qualcuno di voi conosce altre funzioni "strane", e' pregato di lasciarmi un messaggio.. Buon divertimento in radio.. ************************ * 73 de Luca * * I K 5 P W C * * QTH:Prato JN53NU * * BBS:IK5MEP.ITA.EURO * * ip address: [44.134.208.143] * ******************************** ========================================================================== UNDOCUMENTED TM-732A FEATURES CLONE MODE Hold down the F and MHZ keys while turning on power. The current control band will display CLonE. Pressing CALL initiates the data transfer, graphically illustrated by a moving S-METER display. No RF is transmitted during data transfer, instead it is assumed that the data is dumped out of the microphone port. Nothing more is known about this at this time. AM DETECTOR CONTROL The AM Detctor, which automatically comes on below 136 MHz, can be forced ON at any VHF frequency by pressing the F and MUTE keys while applying power. Radio continues to transmit FM but receives AM. Changing frequencies or memory channels will cancel the forced AM mode. This capability could be useful for listening to the USAF Thunderbirds which sometimes operate in the 143 MHZ band using AM. ----------------------------------------------------------------------- Well, that's it for now. Please let us know if you can discover any of the other undocumented features available on the new rigs. -fred -- | Fred Lloyd AA7BQ, Systems Engineer Fred.Lloyd@west.sun.com | | Sun Microsystems Computer Corporation ...sun!flloyd | | Phoenix, AZ (If it's a fact, I believe it!)

Resistor numbers clearly marked on board along top. 800 MHZ RECEIVE To enable 800 receive, switch to UHF VFO (not available in UxU), press and hold MHZ button until 800.000 appears. A capacitor must be added (C348) to enable the 800 receiver. To add, remove UHF transciever board and next to the pad of pin 1 of IC-202 (on the foil side), add a 2.2 pF chip capacitor. A wire can be used instead of the capacitor but sensitivity will be reduced. (See schematic diagram for reason). HARD-WIRE CLONING (Works in all confguration modes) This procedure allows you to clone the entire memory of a "master" transciever into the memory of a "slave" transciever. First, construct an RJ-45 Jumper cable as follows: ------| |------ UP ----------------------------- UP Note that PTT and DOWN E ----------------------------- E are crossed end-to-end PTT ----------------------------- DOWN DOWN ----------------------------- PTT ------| |------ For hacker's reference: UP=CLK, PTT=SO/, DOWN=SI 1. Configure the master transciever's memories as desired. 2. Switch power OFF, hold down F and MHZ keys and switch power back on while holding keys. Display will show "CLonE". 3. Set the slave transciever in the clone mode (as in step 2). 4. Plug the cable into the two radios (which end does not matter). 5. Press the CALL button on the master. When "End" is displayed, operation is complete. ON AIR CLONING (Does not work in K1 or E1 Mod modes) This procedure allows you to clone a second transciever as above, over the air. The data is transmitted automatically using DTMF tones. During transmission (which is one-way only), the master will automatically switch to LOW power. To be legal, use only a UHF cloning frequency. This procedure is not enabled in the stock transciever. At a minimum, you must cut the green wire to make it work. 1. Configure master transciever's memories as desired. Select a UHF simplex transmit frequency and set PTT to UHF (will work on VHF but is not recommended). 2. Switch the power OFF. Press and hold the CALL and DTSS buttons and turn the power back ON. "CLonE" appears in display. 3. Set the receive frequency on the slave transciever the same as that of the master. Turn power OFF, hold down CALL and DTSS keys and turn power ON. "CLonE" appears in display. 4. Press the PTT on the master's microphone. Data transmission will begin. In case of a receive error, the slave transciever will display "Err". When the procedure is complete, both radios will display "End". THE FOLLOWING FEATURES ARE UNVERIFIED, SO YOU MAY NEED TO EXPERIMENT FOR YOURSELF PAGING ANSWERBACK (Does not work in K1 or E1 Mod modes) The exact operation of this feature is unclear but the following description has been given: 1. To enable, hold down the F key and press the TONE key. 2. Do disable, repeat step 1 When enabled, documentation says: "If a matching code is received and the other transciever is no longer BUSY, the code of the local transciever is sent to the other transciever. The answerback function then turns off." MEMORY RECOVERY (requires DTMF microphone) (Documentation of this "feature" is difficult to comprehend but perhaps someone will figure out what it does.. I suspect that "RECOVERY" refers to returning the memories to their original state after changing the split memory layout.) 1. Hold down F and C.SEL, turn on power 2. Press D, followed by 7 on the microphone. "Inspection Mode" is now enabled. 3. To cancel, press and hold F and then C.SEL "Note: Before recovery, the memory channels must be returned to the previous state (number of split memories, etc.)." -- | Fred Lloyd AA7BQ, Systems Engineer Fred.Lloyd@west.sun.com | | Sun Microsystems Computer Corporation ...sun!flloyd | | Phoenix, AZ (If it's a fact, I believe it!)

First, there's no real-time clock, no sleep timer, no programmable ON time/ OFF time feature. There is an APO (automatic power off) with a preset time of 2:59:00 of inactivity until power down. Another complaint is the slow scanning speed. The unit will scan VFO or memory at no more than about 5 channels/frequencies per second per band. I consider this to be terribly slow in today's age. The slowness is probably due to the fact that the remote contains all of the scanning logic and because the data path between the head and the base is over a 2 wire serial data stream. Anotherp erennial complaint is that the radio does not cover the entire UHF frequency band of 420-450 Mhz. As shipped, the unit will only operate over the range from 438 to 450, (transmit or receive) which I find objectionable. The manual is of typical quality and fairly complete although not well indexed. There are so many functions that a cheat sheet is needed but as mentioned, was sadly not included. In typical fashion I note that the Japanese have never been able to adequately and clearly explain how DTMF Squelch and Paging works. They've tried diagrams and jinglish explanations but in the end you still end up reading the instructions over and over before you fully understand them. I'd love to see a plain English discussion of how the DTMF features are intended to work and how they really work in practice. Fllow that with a step by step example and we'd probably have something that could be more popular. One of my reasons for buying the radio was to use the remote mounted head option. The option, the PG-4K kit, is advertised as a 13 foot extension. What you don't find out until you buy it, however, is that only the display cable is 13 feet long and the microphone cable is only half that! To me this meant that although the display cable would let me trunk mount the base, there was no way I could get by with a 6 foot microphone cable. The solution: buy the PG-4M(?) which is the longer model for another $30! Needless to say, I'm not a happy camper! Are you listening Kenwood???? On a positive note about the remote cabling, at least with the 732 it is possible to roll your own. The 4 conductor head to chassis connector cable could be easily spliced and extended, and an ordinary RJ-45 extension cable could be used for the microphone. For many folks, however, it's probably easier to just buy the short ($47) or the long ($78) cable kit. The extension cable issue aside however, it still looks like it will be a very good radio. As always, after spending a big wad of cash I'm automatically inclined to say that I like the radio. This is no exception, the TM-732 does a fine job at heading off the competition at a good price-performance point. The price is the same as the older TM-731 which was around $650 retail (real price, not the bogus MSRP). To conclude, I think Kenwood has come up with a fine replacement for the 731, and has put a lot of thought put into the design of the 732.
