The problem is hams expect things to cost near nothing and prices
never to increase.
ARR Gasfet preamps* sold for years at $79.xx yet cost of material are
rising. Last I checked they still use the mgf-1302 yet where is one
able to find one? The mgf-1302 provides a reliable 0.5 dBNF and
about 22 to 25 dB gain.
PGA-103+ appears to get 0.6 dB gain with about 15-18 dB gain
If you are a small mfr you do not get the volume parts discounts so
materials represent 80% or more of your price and return on labor
does not justify working. When I built DEMI transverter kits for
$100 in labor I made $100/16 = $6.25 per hour. I finally quit as I
thought about doing something else in my retirement.
WA2ODO has quit the preamp business (age & health). For $85-110 you
don't make much for your time once the cost of materials is paid.
*non RF switched versions
Spend $95 each for two coax relays and add to $79 and see how cheap
you can make a switched one for yourself. Yes, some pcb relays can
be used if you can figure out how to eliminate inherent
inductance/capacitance. RF-sensed switching preamps are still "hot
switched": RF arcs across the contacts as the relay closes. Only
with a switched preamp under sequenced dc control is the device truly safe.

For those home-brewers among us:
If you just want something to fix the inherently high noise figure of a
FM HT, you might try using, for 70cm and 33cm, the MAX2640. It can be
obtained for ~$3.75 in qty 1 on Digikey.
Here's an application note[1] which matches it for 433MHz, close enough
for the satellite band. They claim 1.17dB NF, which is not EME class but
works great for the Fox satellites.
I have built up this circuit and can attest to its effectiveness in
front of my Alinco DJ-580T. No picture of this setup, but I can post it
later.
I've also used a classic U310 (J310, MMBT310) design on 2m to great
success. It's not the neatest layout[2], but it seems to work fine.

Mine worked fine. Did you remember to backup your old data before the
install? After the install, I restored the old data and worked fine.
Also, I wonder if Eric is going to upgrade the number of satellites that
Wisat32 to accommodate more than 12?

HuskySat Paving the Way for Cooperation
As previously reported by ANS, HuskySat-1 achieved orbit last week
aboard the Cygnus cargo vessel, which docked to the International Space
Station on Nov. 4. The satellite is scheduled for a boost to higher
orbit and deployment in January. Following completion of its primary
mission, it will be turned over to AMSAT for operation of its linear
transponder sometime in the second quarter of 2020.
Jerry Buxton, N?JY, AMSAT VP - Engineering, explains that this partner-
ship presented some regulatory challenges, but has paved the way for
similar partnerships in the future:
"The Part 97 license that AMSAT will operate under does not include or
allow the use of any of the experiments on board. As those experiments
were not able to conform to the Part 97 so called 'educational
exemption', including the K-band radio, that is ultimately why two
licenses were required. Part 5 Experimental is operated by UW for
everything including the telemetry downlink of the AMSAT transponder
module, and the transponder must remain off during that operation. Part
97 operation by AMSAT will solely be the AMSAT transponder module.
"This was the first partnership with an educational institution where
an AMSAT radio was flown on a non-AMSAT (UW in this case) CubeSat. In
the process of working with the FCC and NASA to obtain a single Part 97
license that was not complicated or restricted by "pecuniary interest",
the experience developed an understanding with FCC as to how a mission
such as HuskySat-1 could be fully licensed under Part 97. There were
delays and difficulties in executing all of the requirements to qualify
Part 97 and that ultimately carried on up to the mission deadline
requirement for having a license in hand in order for HuskySat-1 to be
integrated on the LV. The only way forward at that time, in order for
UW to make the launch, was to do the separate licensing.
"It was lots of work and some good frustration along the way. I thank
and commend our partners at University of Washington as well as the FCC
for their work to make it happen, and our friends at NASA for giving us
the opportunity to push for a path to amateur radio licensing for more
of the CubeSat launches they sponsor. I believe that it has resulted in
a known path toward fully Part 97 licensed educational(e.g. university)
CubeSats. That should in turn offer more opportunities for AMSAT radios
to fly as the communications package for a mission as well as an
operating amateur radio satellite, in the same way as the CubeSats we
produce."

WRC-19 Debates Satellite Allocations
The Radio Society of Great Britain (RSGB), International Amateur Radio
Union (IARU), and ARRL have posted updates on activities at the 2019
World Radiocommunication Conference currently taking place in Sharm El-
Sheikh, Egypt.
One early agreement was to turn down requested changes to one of the
amateur satellite allocations. The band 47.0 - 47.2 GHz was allocated
solely to the Amateur and Amateur Satellite Services by the 1979 World
Administrative Radio Conference (WARC-79). Commercial wireless broad-
band industries had expressed interest in the band being designated
for International Mobile Telecommunications (IMT), and there was some
concern that such a proposal might be made at WRC-19. The fact that
none was forthcoming was due in part to the work of the IARU at the
Conference Preparatory Meeting earlier this year and in the six re-
gional telecommunications organizations. The WRC has agreed to "no
change" at 47.0 - 47.2 GHz.
One of the most difficult issues facing WRC-19 is to develop an agenda
for WRC-23. Dozens of proposals for agenda items have been suggested,
and they cannot all be accommodated. One proposal being introduced for
the next World Radio Conference in 2023 is protecting the Radio Navi-
gation Satellite Service (Galileo, etc.) from secondary amateur usage
in the 23cm band (1.2 GHz -- the amateur satellite band is between
1260 MHz and 1270 MHz for up-links only).
Future mobile/IMT (cell phone) allocations were also being discussed
in the 3-18 GHz range (including our 10 GHz satellite band). Another
item may even affect 241 ? 700 GHz. However, it will be a while before
the WRC-23 agenda gets agreed at this conference, and these items may
or may not be up for debate at the next conference.
Daily bulletins on the progress of WRC-19 are being posted at:
https://rsgb.org/main/blog/category/news/special-focus/wrc-19/
During this period of World Radio Conference, one place to follow the
events and issues is on The ARRL discussion group for the Interna-
tional Amateur Radio Union. The group provides a forum for anyone in-
terested in the work of the IARU. It is open to participants anywhere,
whether or not they are members of an IARU member-society. Additional
information and a link to join the group can be found at

Electron Booster on the Pad for Rocket Lab?s 10th Mission
Rocket Lab has announced that its next mission will launch multiple
microsatellites in a rideshare mission representing five different
countries. The launch window for Rocket Lab?s tenth flight, will open
November 25, New Zealand time, and take place from Rocket Lab Launch
Complex 1 on New Zealand?s Mahia Peninsula.
Onboard this rideshare mission are six spacecraft comprised of 5cm
PocketQube microsatellites from satellite manufacturer and mission
management provider Alba Orbital. Two of these satellites include
downlinks in the UHF amateur radio band.
TRSI is a PocketQube for technology demostration. Its main objective
is to show which functionality can be achieved with dimensions of
5cm x 5cm x 5cm. It carries two experiments that are connected to
the amateur-satellite service.
+ First is a waterfall experiment which will show an image in the
waterfall diagram by hopping the frequency within its transmission
band (image-type beacon).
+ The second experiment is to analyze RF reception capabilities from
LEO with a novel detector receiver and a small patch antenna. It
was designed to test if small satellite receivers which don?t need
deployable antennas are feasible. The received signal?s envelope
will be sampled and forwarded using UHF in MFSK for signal ana-
lysis. During the experiment phase the satellite will also perform
as an amateur CW repeater, providing additional RX strength indi-
cation; eg. CW morse signals will be re-sent in MFSK, showing the
RX amplitude in dBm. A downlink on 437.075 MHz has been coordinated.
IARU Frequency Coordination information has been posted at:
http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=649
FossaSat-1 PocketQube by AMSAT-EA which has a 5x5x5cm structure and
a total mass of 250 grams. Radio link testing features a new experi-
mental RF chirp modulation called LoRa which greatly improves the link
budget reducing the power consumed and reduces the cost of receivers.
The output power from the transmitter required for the correct recep-
tion during a pass is also very low at well under 100mW, being spread
spectrum at such low power it poses no interference risk. It operates
at a considerable level below the noise level of other systems and
would cause no interference to weak narrowband signals.
Students & amateurs will be able to receive telemetry from the satel-
lite with inexpensive hardware, expanding & promoting the amateur sat-
ellite community with youth. Uplink challenges will also be carried
out with rewards for amateurs.
The mission is completely open source with all information regarding
the design of the satellite & how to decode its information clearly
laid out & hosted by AMSAT-EA. The site will provide decoding soft-
ware for SDR use in order to allow anyone to decode LoRa using common
existing hardware & host software for users to submit telemetry data,
making all data public and rewarding users with certificates & awards.
The UHF downlink plans on using FSK RTTY 45 BAUD ITA2, 100mW 183hz
Shift and LoRa 125kHz, Chirp Spread Spectrum Modulation, 180 bps,
100mW. A downlink on 436.700 MHz has been coordinated.
IARU Frequency Coordination information has been posted at:
http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=652
A commercial payload on board is ALE-2 from a Tokyo-based company
creating microsatellites that simulate meteor particles. See
