Un nou site cu si despre radioamatori

|Tot scobind prin maruntaiele internetului dupa niste documentatii referitoare la hobby-ul meu, radioamatorismul si statiile de emisie receptie, am dat peste un site tare misto si cu niste perspective de dezvoltare net superioare! Este vorba de www.radioamator.eu.
Site, e cam prea mult spus. Practic, este un forum bine structurat, asezonat cu o galerie de imagini care, prevad, se va dezvolta in lunile care urmeaza.
Ideea de la care porneste este buna, in romania existand destul de putine site-uri cu acest profil iar cele care exista deja sunt usor infantile sau prea batranicioase, in opinia mea. Era timpul sa apara ceva axat pe continut si nu pe aspect, iar baietii (sau fetele) care au pus asta pe picioare imi dovedesc ca stiu cam ce se poate scoate de la un simplu motor de forum!
Sunt curios sa vad cum va evolua pe viitor!
Galeria de imagini este aici.
Site-ul necesita o inregistrare cu o adresa valida de e-mail. Hei, asta poate fi un motiv de temere caci acea adresa este posibilsa inceapa sa fie sufocata de spam, dar, what the hell, eu am deja o adresa de email facuta special pentru inregistrari pe site-uri! Si nu sufera prea mult!

Echolink Bucharest

UPDATE:
Due to the timless life I have, I was unable to run on a permanent basis this Echolink node.
Fortunately, it is another one here, full time available, YO3KYD which cover the city of Bucharest!
You are invited to access this node!
INFO on YO3KYD-L:
Freq: 145.550 FM
CTCSS:103,5
Node number: 379326


Meantime, I found a Motorola GM900 radio for the UHF echolink node!!! I hope I'll find some time to setup the UHF node here in Bucharest!

This week-end I started again the Echolink 2m node.

There was no more echolink node for Bucharest in he past year due to some malfunction in the yo3hcv-l we experienced. That node was running for more than 3 years with the help of 2 friends, YO3FUU and YO3HCV. It's a pitty because we have had a "vanity" node number, 144.900 which was the frequency on which we run the VHF node.
Now I started the VHF node, but the one designated for UHF, in 144.300 Mhz. I plan to find a UHF Motorola radio to make it work under YO3HJV-L callsign, but I think this will be next year as will be a entirely private investment.

I intend to keep this node operational as long as I can.

Here are the info's:
Frq: 145.300mhz, CTCSS 103,5, node number:43750
Max key down: 210 sec, for both TX and RX to and from Internet.
Output power: 50W, antenna heigh is around 45m, so I will expect a good coverage of 80km around.
The radio is Kenwood TS2000X, Rigexpert+IBM Thinkad T43.
The node is in beta. I plan to use a dedicated radio I have around, Icom IC2100H with a dedicated antenna. Something like an open dipole for a good omnidirectional coverage.
Please feel free to call !

Big, very "tech-looking" radio but versatile and sensitive!

I have owned the radio for more than 3 years and I sold it... Again, like with my FT-857D, this radio is back in my shack after passing a few fellow hams.
First, I have to say that the original stock antenna is one of the worst I have ever seen! But with a real dual band antenna, the things are changing! I used a Diamond RH771S and now I use a Kathrein K7151219 GainFlex antenna.

What I like

Is a real dual bander! This means that you can listen simultaneous on two different frequencies! The possible combinations are: V/U (reccomended), V/V, U/V, U/U. Add to this the two VFO's per receiver and you have a lot of possibilities!

Feeling. When you keep it in your hand, it feels very solid. The back-case is real-metal.

Cross band repeater. This radio performs a cross band repeater and it does well! This is usefull when in mobile operations, and emergency communications when a external antenna will be a plus! And a nice feature is that you can monitor the communications directly in the radio's speaker. Can work as one way repeater or two way cross repeater. Also is full duplex capable!

Battery life. The radio have a extended range of operating voltage. Somewhere between 4V-13V. So, a 9,6V EBP-36N will last about a week on a moderate receiving operation.

Simplicity in operation. The radio isn't "menu driven". The functions are very easy accesed from F+Key.

Good audio reports. On both receiving and transmitting!

BNC connector for antenna. Is very easy to connect a external antenna for mobile use. Also very easy to replace broken connector.

Good locking mechanism for battery.

Good place for external PTT Microphone/Speaker.

Front end attenuator. This can improve the IMD figure when the radio is use with a mobile external antenna.

Good AM receiving. I often monitor the Airband and the radio is good on this. But not with the stock antenna!
Normal 3.5mm jack for headphones. Is easy to use regular headphone, for one ear, to monitor when walking... No expensive accessory for listners!

I don't like

The radio becomes very hot. Even the power is set to M, the radio will be hot on about 5 minutes of transmission, so if you plan to use it as a cross band repeater, you have to put a fan on the radio!

The keypad inscriptions will be erased in months of moderate usage though the inscriptions above de key (the one on the case) will last for years!

Poor PTT, MON and secondary PTT switches and rubber. The rubber will break. I changed the PTT microswitch after 2 years.

Volume and Squelch controls. I wish I have knobs for volume and squelch for the two sections!

No alpha tags on memory. This can be annoying when you are a "listener" like I am. Hard to remember what frequency is!

No CAT. Can't programm with a cable tough there is a way to save the channels by Air Cloning. You have to record the DTMF's which are sent by the radio with another radio.

Other things about this radio

Is very solid, the screen light can be set on continuous by pushing F+LAMP, the radio have a lot of paging options. Is slow on scanning so I use it to monitor two frequencies instead of scanning. Also a nice feature is the band scope which works OK because it used the other receiver to "take the picture".
By default, the number of memory channels alocated for the two sections is equal but You can change this very easy. (by default 80+80 memory channels).
The radio use in the final stage hybrid modules and the measurements show around 7W on VHF and 6 in UHF when use 12V. Again, the radio will be really hot!

I am searching for a new case for the radio, new keypad and rubbers for PTT.

Overall, the radio is a "power-horse". Is best for backpacking but to heavy for pants! Alinco did a good job. This may be "the last true dual bander" from Alinco!

Here are the specifications from Alinco:

I can't attach here the user and service manual but you can ask me to send by e-mail in pdf. format.

Below, the schematics in gif format:

How to disable System Beep - Dezactivarea sunetului de sistem

Tested on XP Home Edition and XP-Pro SP2.

This post is useful for Digimodes especially when the computer's audio output is wired directly into the transceiver and VOX is used for PTT. Maybe you noticed that a system error (like two keys on the keyboard pushed simultaneous) give a loud "ding" sound into the speaker. On a big desktop PC, the system beep will be heard from the main board buzzer but on a laptop, the sound will be generate directly into the speakers. It's shure that we don't want to be sent over the air by VOX feature on the transceiver!
So, how to disable this without compromising the speakers?
Simple:
First, go to START>SETTINGS, then select SYSTEM.
From SYSTEM, select DEVICE MANAGER.
On Device manager window, in the menu bar, select VIEW and then, SHOW HIDDEN DEVICES. Look in the list and you will see "BEEP" listed. Right-click on it!
DISABLE is the magic word!
So, that was!

Testat pe Windows XP Home Edition si Windows XP-PRO SP2

Urmatoarele instructiuni sunt utile celor care folosesc un laptop conectat la un transceiver pentru modurile digitale, iar pentru trecerea in emisie se foloseste functia VOX.
Dezactivarea alarmei de sistem (un beep puternic) se poate face foarte usor parcurgand urmatorii pasi:
START>SETTINGS>SYSTEM>DEVICE MANAGER.
In fereastra DEVICE MANAGER, meniul VIEW se desfasoara oferind optiunea SHOW HIDDEN DEVICES.
In lista de periferice va fi afisat "BEEP". Apasati cu butonul dreapta al mouse-ului pentru afisarea meniului contextual. In acest meniu, selectati optiunea DISABLE.
