Un nou webpagina cu si despre radioamatori
Webpagina, e cam prea mult spus. Practic, este un forum bine structurat, asezonat cu o galerie den imagini care, prevad, se va dezvolta ter lunile care urmeaza.
Ideea den schuiflade care porneste este buna, te romania existand destul den putine site-uri cu acest profil iar cele care exista deja sunt usor infantile sau prea batranicioase, ter opinia mea. Era timpul sa apara ceva axat pe continut si nu pe opzicht, iar baietii (sau fetele) care au pus asta pe picioare imi dovedesc ca stiu cam ce se poate scoate den schuiflade un simplu motor den forum!
Sunt curios sa vad spunk va evolua pe viitor!
Galeria den imagini este aici.
Site-ul necesita o inregistrare cu o adresa valida den e-mail. Heidecultuur, asta poate fi un motiv den temere caci acea adresa este posibilsa inceapa sa fie sufocata den spam, dar, what the hell, eu am deja o adresa den email facuta special pentru inregistrari pe site-uri! Si nu sufera prea mult!

Due to the timless life I have, I wasgoed incapable to run on a voortdurend poot this Echolink knot.
Fortunately, it is another one here, utter time available, YO3KYD which voorkant the city of Bucharest!
You are invited to access this knot!
Informatie on YO3KYD-L:
Knot number: 379326
Meantime, I found a Motorola GM900 radio for the UHF echolink knot. I hope I’ll find some time to setup the UHF knot here ter Bucharest!
This week-end I embarked again the Echolink 2m knot.
Now I began the VHF knot, but the one designated for UHF, ter 144.300 Mhz. I project to find a UHF Motorola radio to make it work under YO3HJV-L callsign, but I think this will be next year spil will be a entirely private investment.
Frq: 145.300mhz, CTCSS 103,Five, knot 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 knot is te beta. I project 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 !

Very first, I have to say that the original stock antenna is one of the worst I have everzwijn seen! But with a real dual relatie antenna, the things are switching! I used a Diamond RH771S and now I use a Kathrein K7151219 GainFlex antenna.
Normal Trio.5mm jack for headphones. Is effortless to use regular headphone, for one ear, to monitor when walking. No expensive accessory for listners!
By default, the number of memory channels alocated for the two sections is equal but You can switch this very effortless. (by default 80+80 memory channels).
The radio use ter the final stage hybrid modules and the measurements voorstelling around 7W on VHF and 6 te UHF when use 12V. Again, the radio will be truly hot!
Tx: 144.000-147.995/438.000-449.995 MHz
Rx: 108.000-173.995 AM/FM /438.000-449.995 MHz

Here you can find a solution for a “military-like” backpack radio based on FT857D.
Two masculine RJ11 and 3m of 6 wire telephone cable for vuurlijn panel, one masculine and one female RJ45 and 3m of 8 wire FTP cable for microphone.
The main kwestie is how to find a decent receptacle for the gevelbreedte panel. Well, this rceptacle is right on the radio, and is immobilized on Four screws. It’s part number on the service manual is RA0450600 spil shown on the picture below:
It is the best solution for who is interested ter a voortdurend mobile solution. Why spend a lotsbestemming of $$$ on a “mobile separation kleefstof”.
Klein, total featured, modern look
Crammed into the little enclosure is an 100kHz-500MHz transceiver (receiving. Transmitting is subject to ham plakband limitations) with most of the modern bells and whistles that anyone could want, and which can supply 100 watts on 160-6 meters, 50 watts on Two meters, and 20 watts on the 440 MHz tape.
Is operating te the CW, AM, SSB, FM, and digital modes.
The main purpose of this radio is to be installed spil a mobile equipment, with removable vuurlijn plate which can be mounted away from the main unit.
The single limitation of this kleintje of installation is the microphone and the speaker, which are connected directly to the main unit thus a 2nd cable will be necessary.
I wasgoed very blessed to have a “all band-all mode HF+VHF+UHF transceiver te one opbergruimte. Furthermore, I needed a radio which could be the poot for a very portable station for field use. The FT-857 fills both requirements nicely.
I liked the solid aluminium framework te the central section and how the circuit boards are fitted! A solid framework is the key for a good thermal behavior and also a good backbone for a mobile or portable radio.
The FT-857 is build to last and to sustain a lotsbestemming of mechanical manhandle.
The top circuit houtvezelplaat contains all of the low level electronics. Albeit there is no space left overheen, nothing seems crammed into the space at all.
I spotted a loterijlot of radios from inwards. Also I wasgoed a constructor of radios and other electronic things. It’s like a classic painting what the Yaesu engineers manage to do te this opbergruimte! Nevertheless, their work has made a vormgeving which is logical, clean, effortless to repair and should be very reliable.
The pictur shows the two optional filters.
If space is principal consideration, then the FT-857D is the best all=mode all-band full-power space-saver presently available.
The price also is good! Do not expect to have spectacles like a Kenwood TS2000! It is a very good radio ter it’s price range!
No built-in tuner – I solved this with an outward LDG AT-11MP and zometeen a Z100 also from LDG (ter portable operations) which matches the size of the radio, and will geyser up almost anything. I read a lotsbestemming of reviews for Yaesu tuners and I don’t want to buy one! I also miss a OTT (One Touch Tuning) switch on the pui panel! Could be useful a single switch to waterput a CW, 5W for outward ATU.
