Ameritron AL 811 10/12 meter modification.
Looks like UV920R is of the most awaited transceiver since ever !
It is already almost three months that rumors says that a new dual band mobile radio is going to be relased in the market by Chinese Wouxun.
But till now, April 2011 no one can give an price in Euro here in Europe.Â Same rumors says will be something from 150-200 USD, but probably in the US market, while I believe in europe the price will be higher.
In any case looks very funny, because, is one of the most discussed product on ham forums, but noone knows how much does it cost !
Moreover, in the wouxun.com web site, there is no trace fo this mobile transceiver
This is a project of an easy to build dual band (UHF and VHF) j-pole antenna done with a common TV twin lead and some coax cable.

World-wide famous antenna manufacturer has closed it’s business on 1st decembrer 2010.
This is what I’ve learned by some hams, that have been in touch with Mr. Sergio Berutti formerly Eco Antenne owner.
Causes are not public domain, but everyone suspect has been due to economic factors.
Eco Antenne, has affirmed in the market for it’s economic product line, and for a wide range of antenna product line, allowing many hams to buy HF VHF UHF antennas at affordable prices.
Many dealers have still lot’s of antennas in stock, but will be the last ones. Website is down since a couple of weeks.
I’ve never owned an Eco Antenna, but at least here in Italy, Eco Antennas are very popular.
Good Bye Eco Antenne.
This evening at our local Club Station, ARI Firenze, we had a special event on SDR technology and in particular a Genesis SDR has been presented and tested with behind our club main radio the Yaesu FT-950.
At the event there were aproximately 20 persons, everyone almost interested and curious.
We were not able to make detailed measurements as happened before for the K2 vs K3, but rather has been a good occasion to play with that radio, switching antenna with the FT-950 and comparing signal reception.
First impression has been that selectivity and sensivity of that SDR receiver looks if not superior, at least equal to the FT-950 receiver.
We have also decided to buy a stock of those SDR kits at Genesis SDR and assemble the kits all together. During the event 8 hams joined the builder group and agreed to buy a full 160-6m Kit.
Furthere SDR events will follow in next months, so I will probably keep this blog updated.
This SDR comes in a disassembled kit, and is very small as you can see from the picture. It is connected to the PC via USB for remote control and via the PC soundcard for the audio output while Antenna of course use a standard BNC socket.
Well, I’ve been quite surprised of this toy, since it really works with the 5 volts coming from the USB and is capable of nice filtering capabilities and quick tuning.
We have ecountered some troubles on Winrad setup, even if we have opted for the more clean design on WinradHD.
For those of you that do not know, both software are free windows programs that “define… radio”, the first one is provided to the community by an italian ham I2PHD who also released the code for free, while the second is a remake of the original Winrad by DG0JBJ.
A new Power Meter is arriving in my shack.
I was looking for an accurate and readable SWR Meter for my station, that could cover HF and six meters band, and could support 1,5 – 2 KW.
Budget limitations prohibites high level Array Solutions Power master or Bird Technologies Bird wattmeter, while limited distribution of Autek products in Italy made desist me on evaluatinv the well reviewed VM1.
The choice has been restricted to a couple of products.
The DAIWA CN-801 and the Palstar PM2000 A/M, price are similar, but generally Daiwa product is cheaper.
I choosed the Palstar for the followin features:
True PEP Reading
Average and True PEP Reading Meter in Forward and reflected, looks like the CM-801 offer only Forward and not reflected.
According to reviews the PM2000A offer eccellent accuracy, compared to a Bird meter, while CM-801 looks like accuracy percentage to be higher than what’s documented.
CM-801 is missing the switch so, light is always on, and it’s really annoying. PM2000AM offer a front switch.
The PM2000AM offer an extra cord, permitting to place the Meter almost everywhere in my desk, where room is always rare thing.
Now maybe you are wonderin how much I paid it and where I bought… well I looked among Amateur Radio Dealers in Europe and found a German Dealer offering the product at a very special price, the lowest in the net.
I will reveal the name of the dealer, as soon as the transaction will be completed… you never know.
After evaluating HF vertical antennas I’ve finally choosen and ordered my new vertical hf antenna.
Gap Titan DX is the choosen one.
According to characteristics and price the Titan resulted the one with the best price / performance ratio.
I ordered at Wimo (german ham radio dealer) and it arrived in 3 days via UPS.
Best price and fast delivery, thanks folks at wimo.
