This is my third attempt to post this message.? It seems that the AMSAT-BB
blocks messages with JPEG attachments.? Below is a Google translation of
the article on the 23cm transceiver inDKARS magazine.

VHF-UHF-SHF News
This month provided by Hans van Alphen, PA?EHG
Nice new transistor for 23 cm PA
Since the beginning of this year NXP has a nice power LDMOS transistor
in the range for the 23 cm band.
The transistor type: MRFE8VP13350 assumes pre-matched adaptation and is
designed for industrial, scientific and medical applications. The
transistor is capable of supplying 350 watts in the frequency range 700
to 1300 MHz, which is also ideal for our 23 cm band.
With a typical LDMOS supply voltage of 50 volts, approximately 10 to 14
amps is required to get the 350 watt output with a control of 8 watts, a
comfortable 16 dB gain.
Italian Technology Broadcast offers 490 Euro ex VAT a module for sale
consisting of a built pallet with all parts on it and a copper base of
9.5 mm thick that needs to be mounted on a cooling plate.
Further information and how to order this unit can be found via:
http://vhelectronics.sk/index.php/en/rf-modules-and-boxes/alx-350-detail
For those for whom this power is not yet sufficient, NXP has also
announced a bigger brother, the MRF13750H, which can deliver an output
of no less than 750 Watts in the band from 700 MHz up to and including
1300 MHz. With almost 20 dB gain, approximately 10 Watts is sufficient
to send the transistor. This transistor will probably soon be on the
market and possibly also as a complete one
power pallets become available. Data from this transistor can be found at:
https://www.nxp.com/docs/en/data-sheet/PRF13750H.pdf
70 cm EME with only 10 watts
On 2 December 2017, the M6EBQ succeeded in making a 70cm EME QSO with
DL7APV with only 10 Watt output. The connection in WSJT was made with 10
W output from a Yeasu FT857 and as antenna a DG7YBN 70-17m 17 element Yagi.
The antenna used to design by DG7YBN uses a flat folded dipole with
which very favorable characteristics can be achieved.
The antenna has the property that the side lobes at the back are very
well suppressed and thus a very good front-rear ratio for the length of
this antenna.
With 3.63 meters in length and a gain of 17.3 dBi and a front-back ratio
of no less than 38 dB, this is also a very suitable antenna for
contests. Of course, therefore, there is also little noise picked up and
the antenna is also very suitable for moonbounce.
Information on how to make this antenna can be found at:
http://dg7ybn.de/432MHz/GTV70_17m.htm

I have a yaesu ft-530 hts.
They seem to be ideal as vhf/uhf radios...
It can operate separately...
And the radio can operate in full duplex mode...
I also have a kenwood 700 that I've programmed for all the fm birds...

Looks like an interesting project, although the price of the kit is a
bit more than I'd like to pay for what I'd be using it for: talking to
AO-92 on L-band.
I've been looking into something like a varactor-tuned frequency
tripler, as shown a bit over half-way down this web page:
http://www.sydneystormcity.com/microwave.htm
The schematic is here: http://www.sydneystormcity.com/1296%20Tripler.gif
It may not be an ideal solution but considering how often the L-band
experiment will be active on AO-92, I'm looking at a cost-effective
solution.

Remember that Fox-1Cliff will also have an L-band uplink. And FUNcube on
ESEO?s only uplink will be on L band, so any investment on 23 cm is
actually for three satellites, not just one.

Mac, the arrival I was referencing started on page 20 of the Jan 2018

The links at the end of the article point to the following site of Bas

he offers his kits for about 158 Euros+shipping:

think there is some potential here, and I would like to know other? opinions.

Hi All,
Due to operational constraints, AO73 is now in amateur mode, with the
transponder active and low power telemetry until Sunday evening!
Have FUN

Wow...i am blown away by ISS Detector! Like Don, I passed it by because I
assumed it only dealt with ISS, and not any ham satellites...I had NO idea
it had so many features!
I purchased the Pro version for my tablet, and downloaded the original with
the amateur satellite add-on for my smartphone
Thanks again for the ISS Detector recommendation. Virgilio HP2VX also
recommended this app in a private email to me, and Pedro LU7ABF reminded me
of the AMSAT-Argentina website tracker, so thanks to them as well!
