April 30, 2011 Time to drink a beer and to send one to OZ1DJJ
Because of the image below, the first apearance of my 6m Beacon on the cluster, I have to send a 10% bigger and stronger beer to BO – OZ1DJJ – first ever spotter! At the time he reported my beacon, I was still in bed
) so I’ve seen it spotted only after a search a little bit before the end of this nice day.
So BO, take this Copenhagen Strong one, made in Romania, at least from my personal photo album!

April 29, 2011 Preparing new antenna
As I’ve told you before I have some antenna location problems and of course lot of frustrations because of this.
Today I’ve replaced the mounting next to my window, “upgraded” with a longer suporting aluminium tube from 1 to 1,5 meters long. Also much reliable to powerfull winds.
Next, i will replace the 1.5m vertical (L/4 @ 50MHz) with about 2m long vertical (L/2 @ 70MHz) as I will concentrate this year for this new band. But, of course, it will work on other bands of interest too by using the extraterestrial design that I created with my ultra-extra-super-sexy-mind when I was sleeping. See the beautifull coloured picture painted in oil with my very own hands!

April 25, 2011 The new YO5PBG/B (pictures)
Easter is a good time for other purposes than praying and other stuff for masses. Yesterday I made the PCB and in the evening I already finished the new beacon.
Today, for the first time in the last Century I woke up early, at 8 a.m. and started the work on the box. Than I got a call from a friend, and because of the great weather I enjoyed my first real mountain biking day this year, on the hills near Baia Mare City.
Back home I was again working. Did I mentioned how well do I work when others dance?
So this are some pictures with the new 6m beacon, now up to 4watts. Tomorow it will be back in the second location (“Mom’s Great Location, HI!).

Now, let me drink some beer to celebrate

April 23, 2011 The 50.070MHz beacon is down for maintenance
As Es Season aproaches I have decided to kill my 6m beacon!
I will destroy actual TX PCB and renew the design. It is right now on my desk, I made tests and modified the driver and PA stages, so now instead of 1W I have 4Watts with the same transistors. The prototype that I used until now was made on the run from a transmitter part of an old CB transceiver.
I must tell you that CB transistors are very good for 50MHz, as good as for 27MHz.
I will also change the aluminium case, because I need the actual beacon case for another project.
I will post images when I finish the final/stable design.
Until then, the old, ugly, beacon with the testing changes for power optimisation (click to enlarge images):

April 11, 2011 Some thoughts regarding my activity this year, also about Romania…
I think I had a good start this year. I was more practical, I concentrated my attention much better on finishing project by project, not as I wanted in 2009 or 2010 after of a 4-5 years pause as I was QSY in Bucharest for work and it was impossible for me to do anything about amateur radio. So in the past two years I wanted to do everything in a day and finished with kind of a mess. I made big steps forward but not as I wanted.
End of 2010 and begining of 2011 showed a lot more mature way of “radio-thinking” for me.
From the begining of 2011 I made fast from ZERO two transverters, a transceiver, several improvements to my shack and also started back to work in the bands from a local club, in local contests. Unfortunatelly I Still have’nt put up the antennas, and I’m still unsure about… this year. But 2011 also started with good news in this problem. Some guys offered me good place for antennas and hopefully I will operate from different locations. Of course, home sweet home is better…
I’ve lost contact with some guys that I respected. Once I get strong words for nothing, sometimes based on the only fact that I’m still young.. I say goodbye. I still have principles.
This year I intend to finish all homebrew projects and have some nice contacts from portable: the beautifull hills and mountains near my QTH – Baia Mare City (KN17SP). This year I want to work serioussly at least in a contest: IARU 6m, but only with QRP. Than, beginning with 2012 I will concentrate more and more on DX-ing, new bands, little freaky projects, maybe contesting usually /QRP.
Now for example, my atention will be directed to the remake/miniaturisation etc etc of my All mode – HF-VHF-UHF transceiver. At least…
This Year I’m also atracted by the ideea to publish some of my knoledge in RF, some articles. But beacause I already had a bad start with the romanian mag. (important info was not published, because of doing things on the run), I hope that fellows outside would be better partners.

Now a little bit about Romania, wich at the moment is a general chaos. Idiots are promoted, genious is enslaved. No law, directive etc. is respected by the goverment or anybody else. And heya, we are part of the EU. We have the highest prices in the EU for… refurbished foods and other goods and the lowest income. Economy is down. EU is blind, they see Romania only as a market.
Those who make absolutely nothing …. make a lot of money from nothing.
We have beautiful and very intelligent people, but nobody hears about them. The others, the vast majority is pushed to live in a low degree of knowledge. They are subconstiently forced to refuse enlightment. They aproach the level of stupidity that is not good even for porn films. Disrespect is at peaks.

2. Mini-transverter for 70MHz: >7W output power, 1mW RF input, >10dB RX gain (case and schematic has been made DONE – March 26, 2011)
3. Mini-Transceiver for transverters (portable operating): >1mW TX, min 0.5uV RX sensitivity, min. 400KHz VFO span, microcontroller based digital counter, 94×70 mm front size (IN PROGRESS, today started with the aluminium case, IF/AF unit and some other units already made)
4. Noise Blanker for 6m YO5PBG Transceiver from 2000, V 4.0 (made, tested, to be inserted) — DONE march 8, 2011
5. All mode, HF/VHF/UHF transceiver V.2.0 (need to make new smaller units – 2m unit has now new schematic and PCB made) —- project in stand by until April 2011
6. 2m portable Yagi antenna
7. Improving the new project AMC-1 (with new units like RF and AF generators, dummy loads for 50/75 ohms, antenna analyzer, DSB RX for modulation quality tests etc. —– not a priority but it should be (UPGRADED March 28-29 2011 with AF Monitor, DBM Mixer for RF monitoring and 1KHz Signal Generator)
8. 1296/144MHz transverter — don’t make it a priority!
9. 40~50V Power Supply for HF/50MHz Solid State PA (almost done) — high priority
10. FT901DM new improvements (replace old trimmers, remake adjustments, implement automatics for the new second VFO, implement automatics for controlling up to 5 transverters) —— low priority!
