bbstriker Posted December 14, 2010 Report Share Posted December 14, 2010 No Range is too short to operate PTT placed on the gun. 0.5m was in wide open - nothing between button and radio (for example, no hand pusshing button like it was on the gun) :-/ Signal is to weak or something is wrong with radio/wireptt ? I need someone to compare mine :-/ Ok. I have two of these radios bought from two different vendors at different times. Both remote PTTs work flawlessly when operated from my rifle. Have you tried changing the battery? A weak battery will have an effect on range. Link to post Share on other sites

Tryed, and checked voltage on newone.I'm starting to worry,... mybe my is broken ? Link to post Share on other sites
FiliP79 Posted December 27, 2010 Report Share Posted December 27, 2010 Ok. for the future. Maybe someone need it. I bought new radio. W-PTT button working in my house to 9 meters max ! :-) 6m when two walls between button and the radio. Cool, yea ?! Link to post Share on other sites
Capt Firmin Posted December 28, 2010 Report Share Posted December 28, 2010 so are these radios worth getting? I have one at the moment but have no others to test with and dont want to waste any more money than I have too Link to post Share on other sites
acethaman Posted December 28, 2010 Report Share Posted December 28, 2010 Still desperately trying to get my radio programmed to european frequencies. Anyone with the cable able to help me for a fair monetary compensation? Link to post Share on other sites

socal_recon Posted February 10, 2011 Report Share Posted February 10, 2011 Any idea how to wire it up to program it now? Link to post Share on other sites
Eretik Posted February 21, 2011 Report Share Posted February 21, 2011 Maybe, some of this informaion will be useful: LEMO pins Bowman headset 2 Kenwood Radio throw PTT-button Kenwood equipment connections USB or COM programming cable for Kenwood TK-2207 can be found on ebay. It's name - KPG-22. For example. Idea: 1. Buy KPG-22 2. Cut Kenwood-style connector 3. Plug cutted programming cable to marconi replica and computer 4. Try to programm it Can anybody, who have PRR replica, check it and make a report? But i still haven't any ideas about connecting scheme LEMO on PRR with cutted wires from KPG-22. If somebody have - let me kow, please. Link to post Share on other sites
acethaman Posted February 23, 2011 Report Share Posted February 23, 2011 Problem is, the cable isnt just a dumb cable with each wire from usb going to some wire on the radio. The wire itself has some components. My guess would be, theres somekinda simple microcontroller in there. edit: I just ordered some chinese-copy-Kenwood programming cable and a couple of LEMO connectors. Ill see if I can get anything done with them. Link to post Share on other sites
Federico Posted February 28, 2011 Report Share Posted February 28, 2011 Hi, i will do the same and i will share my results. Plese let me know where did you got the LEMOs. Meanwhile i know there is someone here which was able to find an original programming cable and i would like to know from him if there is any procedure (like press "this" an power on aetc.) to be done in order to put the radio in programming mode. Please reply at least to this question. As an alternative, i'll pay you 200 Euro for the cable. Ciao Federico Link to post Share on other sites
HGButtentee Posted February 28, 2011 Report Share Posted February 28, 2011 ok, since I have one of the programming cables, i will take pictures of what you will need. Also, if you can give me an excact explanation of what needs to be tested by an "certified" electrician i will head over to my Buddy and ask him if he can help. Since these seem to be pretty rare I will not do anything that might destroy the cable....understandable, aye ? @Frederico: Actually you just attach the programming cable which looks just like an PTT Unit with an cable coming out from where the headset goes to your Pc, using the serial port and turn on the radio You then start a software, read the configuration from the radio, edit that and write the new configuration to the radio. Matter of minutes if you have a list of the needed frequencies. Personally I did not configure any of the advanced feature like fleet control, squelch etc. Mainly because I lack the understanding of radio technology.. anyway.. I would rather use this thread, for further reference also then to get loads of PNs now... Link to post Share on other sites

Joke apart, just to start it can be very interesting to understand which are the pins used for the communication and this can be done in two ways: 1st. from the db9 connector to the plate checking if there is a direct connection (very low chance) 2nd. disasselmbling the cable form the "plate" side (not the db9) and trying the same. In fact if we will be able to find where the RS232 is connected to then will be easier to try to connect the "kenwood" cable. Silly bu necessary question: is the radio powered on whe you connect it to the pc ? Thank you very much for your help and time ! Federico p.s.: where did you found that cable ?

acethaman Posted March 2, 2011 Report Share Posted March 2, 2011 If you Google for KPG-22 (which is the Kenwood programming cable) schematic, you will find several different schematics using both discrete components and integrated circuits. My guess is, the original Kenwood cable uses the MAX232 chip (as does about 95% of serial port attached cables for any purpose anyway). So, direct connection is a no. What's more intresting though, is the picture posted by ernesto, showing the LEMO - thru PTT unit - to radio itself is a semi-direct connection. So, there us a very good chance for succesfully building a KPG-22 - LEMO adapter using only connectors and wires, no active components. I ordered the LEMO connectors and KPG-22 replica from eBay, where else http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=360224722442 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=110616141733 Haven't received anything yet, though.

Hi, i am pretty sure too that non direct connection is present because 99.9% there will be a MX232-like IC for the RS232/TTL levelling. What i am assuming is that in the original cable the 232/TTL componentes are inside the module so we "only" need to understand which pins are involved in the connection to the radio. If this is the case then weare right, a LEMO connector and some plug adapters to the KPG-22 will solve definitely our problems. I ask anyway to our German friend HGButtentee to take as much pictures as possible (also macro pictures) so mybe we can recognize some things. I bought a KPG-22 too, now i am looking for LEMO connectors at a good price (found nothing belo 35 Euro / Piece !!!!). Any idea ? Ciao Federico Link to post Share on other sites

HGButtentee Posted March 3, 2011 Report Share Posted March 3, 2011 ok now, here is some close ups I took this morning. As far as I can see this is a direct connection. Now active parts to be found within the cable... see for yourself No Elco or else to be found... an experienced Electrician should be able to build one i guess.. For those of u that lack the skill Seeing and understandig how this can Su%& to have this radio and not beiing able to use it.. I will programm them for you...send me a message and I guess we will be able to make something up Link to post Share on other sites
acethaman Posted March 3, 2011 Report Share Posted March 3, 2011 If you look at the picture at PX-Airsoft webshop (http://www.px-airsoft.com/showroom/model/largepic.jsp?p=../user/1213907847691/gallery/b_1264966285234012953.jpg), note the large-ish size of the D9 connector. There's certainly something in there. Also, looking at HGButtentee's pictures, Im guessing the manufacturer just took the cheapest possible KPG-22 he could find, cut the wire and soldered it (badly) to a stripped PTT unit. If you look at the quality of workmanship on those pictures, its very home-made, not professional looking. Our last problem in solving this might be the "extra" components we have inside the real PTT unit messing up the signal. I reckon its a small chance, but still possible. Now I just need the parts I ordered, dammit! Link to post Share on other sites
HGButtentee Posted March 3, 2011 Report Share Posted March 3, 2011 oh, now i get it..you expect something within the "serial plug"..wait.. i ll pry the thing open.. Link to post Share on other sites

Federico Posted March 3, 2011 Report Share Posted March 3, 2011 GButtentee i will never end to thank you for your help ! From the picture you sent i can understand that: 4 wires used, which means 99% TX Data, RX Data, Ground and +VCC to feed power to the active cable. ICs are presumable inside the DB9 connector This is a picture of a KPG-22 which is showing all the signals: From your inside picture my guess will be: Pin 9 - Gnd Pin 10 - + VCC to the cable (if necessary) Pin 11 - TX o RX data (to be tested) PIN 2 - TX or RX data (to be tested) My i ask to have a complete picture of the board of the same side of the pic. named VERBINDUNG.JPG ? We are so close to the solution ! Last question: had you " a hard time" to disassemble the cable ? Was it glued ? Thank you again Federico Link to post Share on other sites
HGButtentee Posted March 3, 2011 Report Share Posted March 3, 2011 This what you need ? serving u pronto.. ;-) yes it was glued, luckily they were short on glue so it was not to hard.. I seem to have ruined the "serial" housing but I can live with that...I doubt it will ffect the function. Link to post Share on other sites
