TH-D7 PG-4W programming cable diagram

Well, I just received a very nice Kenwood TH-D7G(II) portable VHF/UHF radio.
The main problem was the programming of my favourites frequencies. I started to grab informations from the internet regarding the software I need and, most important, what cable to use.
The internet is very poor in informations about PG-4W, the programming cable, but there are a lot of vendors (from 12 to 25 EUR/cable) which is quite inacceptable for me... I do know how to make a PC to Radio cable!
So, I prepared myself with a RS232<>TTL adapter (with MAX232), one 2,5mm stereo jack and some lenght of cable, a female DB9 COM port and some patience...
First step was to read carefully the User manual where it states that the radio conect directly to the PC.

To be sure I was measuring the voltage on the PC conector at the radio.
It was -6V (RS232 zero logic level) which means the radio has a RS232<>TTL level adapter inside. So, indeed, tha radio connect directly to the PC Com port...
I made the connections, but the software returns (over and over...) a communication error (Timeout).
So, I started to search for a reason. Maybe the software expect some signaling on the other ports of the COM...
I realise that, when I push the "Read Radio" command on PC, on the COM port RTS appeared a voltage swing. Hmmmm..... so, the Radio <> PC cable is not so simple...
So I connected the RTS with CTS and DCD with DTR and, BINGO!!!!, all was OK!
So, here is the diagram of the PG-4W programming cable for the Kenwood TH-D7 portable radio...








 Later Edit: Tom, NV1U sent me the following diagram made on his tablet:

 TNX Tom!


!!!!!!!!!!!!!WARNING!!!!!!!!!!!!!!!
There is NO ERROR!!! The 2,5 mm plug diagram is not reverted!!!
The manual states that the tip is TxD and the ring is RxD. The TxD and the RxD on the plug ARE FROM THE RADIO VIEW
The radio transmit data to the PC by the tip of the plug and the signal goes to the RxD on COM port at the PC!


For programming the radio I use a IBM X61T with a USB<>COM adapter and the MCP-D7G, ver.1.01.

OEM GPS inside TM-D710 Front Panel

Acum aproape un an, scriam aici un post despre cum am adaptat un GPS Holux pentru utilizarea pe TM D-710 cu un minim de conectica.
Am cautat un modul convenabil din punct de vedere al dimensiunilor dar si al pretului. Un alt criteriu a fost acela al sensibilitatii de receptie, intrucat antena urma sa fie obturata de capacul de plastic al panoului frontal.
Am achizitionat de la Farnell un GPS Leadtek LR9552, cu antena incorporata. Dimensiunile sunt de 25x25 mm cu o grosime de aproximativ 7 mm!
Am fost impresionat de cat de mic este modulul; practic, antena acestuia este mai mare decat montajul propriu-zis...


Asadar, aveam in cutia cu "maimute" un modul GPS. (De fapt, mai am unul, HI).
Multa vreme am incercat sa gasesc si conectorul mama, corespondent conectorului existent pe modulul GPS. Nu am reusit sa il gasesc iar astazi, am avut ideea salvatoare, asa ca am trecut la fapte!
Am taiat partea de sus a conectorului si am capatat astfel acces la pini, urmand sa lipesc direct pe ei alimentarea si iesirea de semnal NMEA.
Conectorul este foarte mic, astfel incat operatiunea se recomanda celor cu vedere buna si mana sigura.



Pentru lipirea firelor am folosit un letcon de 25W caruia i-am subtiat varful astfel incat sa nu lipesc mai multi pini deodata.
Conform fisei tehnice, modulul GPS are doua iesiri! TxDA si TxDB.


Intrucat nu stiam care dintre ele este cea care furnizeaza semnalul necesar, am lipit pe toti pinii cate un fir. De fapt, nu imi trebuiau si intrarile la modul, dar, pentru ca mi-a iesit prima lipitura, am continuat, asa, din inertie...
Ulterior, dupa identificarea pinului corect, am dezlipit celelalte fire, ca nefiind necesare.
Proba de functionare am facut-o folosind conectorul lateral al panoului de control si o sursa de alimentare exterioara (o baterie 6F22 de 9V si un stabilizator LDO de 5V). Pinul 2 de la GPS este cel care furnizeaza semnalul necesar (TxDA).

Am desfacut panoul capacul panoului frontal si am desfacut saibele de fixare de la potentiometrii de volum/squelch si de la optical encoder.


Cele doua blocuri potentiometrice sunt conectate pe doua bucatele de cablaj si, desi sunt codificate diferit, in realitate sunt identice ca valori si schema electronica, deci nici o grija ca le-ati putea incurca intre ele la montaj.
Pe placa cu componente exista o folie profilata destinata protejarii cablajulu iin zona decupata a capacului din spate. O puteti ridica fara grija, nu este prinsa nici de cablaj si nici de capac. Sub aceasta folie exista un conector flexibil si este bina sa aveti mare grija cu el!



Desfacem cele doua suruburi care fixeaza cablajul de masca si ridicam montajul.
Conectorul de 2,5mm se gaseste in stanga afisajului LCD si se observa ca este vorba de o mufa care are si circuit de autodeconectare.
In figura de mai jos se vede clar pe care dintre pini conectam firul de semnal de la GPS.


Dupa ce lipim firul de semnal de la GPS, asezam cablajul la loc in panou si folosim o degajare in PCB pentru a trece firul in spatele carcasei.
In stanga conectorului RJ45 ce foloseste la conectarea panoului frontal la unitatea centrala observam un regulator LDO. Acesta este regulatorul care furnizeaza 5V montajului.
Intre regulator si conector, pe cablaj este marcat traseul de 10V. Acest marcaj este facut exact pe traseul de GND, unde ne vom conecta cu pinul 1 de la GPS.
Pinul 7, de +5V de la GPS se va lipi direct pe pinul regulatorului LDO.



Dupa lipirea firelor de la GPS, putem face o proba:
Conectam panoul de comanda si pornim statia. In meniul APRS selectam la INPUT: GPS.
Pornim TNC-ul in regim APRS12 si apasam butonul PMON pentru a observa informatiile furnizate de modulul GPS. Dupa aproximativ 2 minute, la mine a inceput sa dea informatiile de pozitie.
Cu ESC ne intoarcem in regimul de afisare a frecventei si apasam POS. Pe afisaj ar trebui sa observam deja coordonatele locului in care ne aflam, inclusiv cu afisarea careului (KN34BK in cazul meu).
In partea din stanga sus a afisajului, va clipi "GPS"; semnificatia este aceea de semnal NMEA coerent.



Oprim statia si deconectam panoul de comanda pentru etapa urmatoare.
Dupa ce am verificat functionarea corecta, eliminam de pe capacul din spate ghidajul destinat unui beeper (nu stiu care era rostul HI). Aplicam o bucata de folie dublu adeziva pe care vom lipi modulul GPS, chiar pe partea cu antena de receptie. Am observat ca nu influenteaza cu nimic performanta receptorului GPS.


Fixam modulul dupa cum se observa din imagine si inchidem capacul de la panoul de comanda.

Din acest moment, avem un TM D-710 cu GPS incorporat in panoul frontal!

Imi cer scuze pentru calitatea imaginilor dar am folosit ce aveam la indemana, adica un telefon mobil.

Mai jos sunt cateva informatii despre modulul GPS folosit:

Chaos on 6712 kHz (HFDL basic freq)

A couple of days ago I was monitoring 6712 kHz.
The frequency is listed for Reykjavik Ground station, but on the air was Krasnodarsk Ground station.
As was not enough strange, on the same frequency a lady was dictating numbers... No, it was not a "Numbers station" in the classic mean. It sounds more like a network controller...
At the top, was a Jamming signal...

After a few minutes, the lady ceased transmission and Reykjavik GS was back on the air!!!

Very strange!

Here is a record.

Air traffic on 5655kHz

This evening, as usually, I was monitoring 5655kHz for some air traffic.
And there it was!
I was able to receive and decode HFDL from HAT-Yai Airport from Thailanda.
What was very unusual was that, on the same frequency, I was able to hear some USB Phone operations.
Anyway, It was impressive that the signal was very clear and noiseless!

Romanian Numbers Station

Putini sunt cei care isi arata preocuparea pentru asa numitele "Numbers Stations" la noi in tara.
Sub aceasta titulatura se ascund anumite emisiuni destinate agentilor care opereaza in tari straine, sub acoperire.
Tehnic vorbind, este vorba de un emitator, de regula in gama undelor scurte, ce transmite siruri de cifre, prearanjate dupa un anume algoritm, intr-una din gamele de frecventa folosite de emitatoarele de radiodifuziune comerciale sau nationale, de regula in modulatie de amplitudine sau in modulatie cu o banda laterala suprimata.
Sirurile de cifre reprezinta un mesaj criptat printr-o metoda de unica folosinta (tabla de criptare).
Mesajul este adresat unui agent care detine tabela unica de decriptare si care, prin folosirea acestiea, recupereaza mesajul.
Principalele avantaje ale acestei metode de comunicare (unidirectionala) sunt:
-posibilitatea ca agentul sa preia mesajul indiferent unde se gaseste pe teritoriul strain;
-absenta riscului generat de posesia unor mijloace specifice de comunicatie cu centrala de operatiuni;
-rezistenta la penetrare a codului folosit.

Ce se stie mai putin este ca si Romania a folosit astfel de metode de transmitere a mesajelor catre agentii sai din strainatate!

RACAL Panther 2000-V - Tactical radio




This is how it sounds!

The Panther V Enhanced Data Radio (EDR) is a core element of the latest generation Panther EDR frequency hopping military radio family. It represents the smallest and lightest tactical 20 watt manpack and vehicle radio available today, offering un-paralleled Electronic Protection Measures (EPM), data and user capabilities in the 30 to 108 MHz military radio band.

Panther V, although available as a 20 watt manpack, has co-site filtering built in to the basic transceiver. By connecting the radio directly to the 24-volt vehicle supply, Panther V will operate as an extremely compact 20-watt vehicle station in multi-radio installations. For higher power, Panther V connects to a vehicle interface unit providing a power output of 50 watts. Even in this high powered role, the volume of Panther offers considerable savings over similar radios from its nearest competitors.
