Get ready for 2m MoonBounce communications EME Earth Moon Earth


we are very interested in EME and always have been... i got the antenna for it and i am ready to go.

i have the Cushcraft 17B2 http://www.cushcraftamateur.com/Product.php?productid=A17B2

i have the 50 watts 2 meter radio

i just need the TIME

shoot me an email if you are also into and interested in EME

here is a great link to help you get started

Moonbounce is often equivalent with large antennas, low feed line losses, T/R relays, LNA's, HPA's,
Weaksignal detection, Moon tracking, lots of labor and system maintenance.







Amateur-radio moonbounce generally requires the following:

A sensitive receiver with a narrowband filter

A transmitter capable of operating on at least one amateur band above 144 MHz, and capable of producing 1500 watts of continuous radio-frequency output

An antenna with high directivity and gain, capable of being rotated in both the azimuth and elevation planes

A location in which the moon can be seen without obstruction for extended periods

A location in which humanmade radio noise is minimal

Neighbors who will tolerate the presence of a large antenna and the proximity of a high-power radio transmitter

A neighborhood without ordinances or covenants prohibiting large antennas and/or high-power radio transmitters

Operating skill and patience

BPSK31 how to


Want to to learn a Digital mode for AMATEUR RADIO? BPSK31

First of all what is PSK:
What is PSK?
– PSK is an acronym for Phase Shift Keying. Information is transmitted
through patterns of polarity-reversals (180 degree phase shifts), hence the
name.
– Narrow-band, low-power, soundcard-generated radioteletype mode for
keyboard chat.
– Three data rates, 31, 63 and 125 baud. Bandwidth increases with rate.
– PSK31 is the most commonly used, its data rate is close to the speed of the
average typist.
– PSK is resistant to interference but has no error control, so it's not suitable
for transfer of data files. © 2013 Eric Fowler / WV3E – All rights reserved.

HERE IS WHAT YOU NEED:

Fldigi is a computer program intended for Amateur Radio Digital Modes operation using a PC (Personal Computer). Fldigi operates (as does most similar software) in conjunction with a conventional HF SSB radio transceiver, and uses the PC sound card as the main means of input from the radio, and output to the radio. These are audio-frequency signals. The software also controls the radio by means of another connection, typically a serial port.

Fldigi is multi-mode, which means that it is able to operate many popular digital modes without switching programs, so you only have one program to learn. Fldigi includes all the popular modes, such as DominoEX, MFSK16, PSK31, and RTTY.

Unusually, Fldigi is available for multiple computer operating systems; FreeBSD™; Linux™, OS X™ and Windows™.

how to recognize the bpsk31:

Recognising the different modes comes with experience. It is a matter of listening to the signal, and observing the appearance of the signal on the tuning display. You can also practise transmitting with the transceiver disconnected, listening to the sound of the signals coming from the computer. There is also (see later paragraph) an automatic tuning option which can recognise and tune in most modes for you.

The software provides a tuning display which shows the radio signals that are receivable within the transceiver passband. Using a point and click technique with the mouse, you can click on the centre of a signal to select it, and the software will tune it in for you. Some modes require more care than others, and of course you need to have the software set for the correct mode first — not always so easy!

The RSID (automatic mode detection and tuning) feature uses a special sequence of tones transmitted at the beginning of each transmission to identify and tune in the signals received. For this feature to work, not only do you need to enable the feature in the receiver, but in addition the stations you are wishing to tune in need to have this feature enabled on transmission. Other programs also offer this RSID feature as an option.

10-10 Spring Digital QSO PARTY 0001 UTC Saturday through 2359 UTC Sunday.


Spring Digital QSo Party
Export Event

From Saturday 25 April 2015
To Sunday 26 April 2015


Location : 10 Meters
Contact : Dan Morris KZ3T
Logs must be postmarked NLT May 11, 2015
tentencontest@ten-ten.org
dbmorris315@gmail.com (Alternate)

Upload logs at the KJ4IZW if possible, otherwise email logs to either of above addresses.

Spring Digital - held on the last full weekend in April. 0001 UTC Saturday through 2359 UTC Sunday.

5.2.3 FREQUENCY AND MODES

Direct unassisted contacts only are permitted. Repeater, Satellite, IRLP, Echolink, or any other similar type of assisted contacts are NOT allowed. Based on the appropriate band plan for the country of operator, CW QSO Parties should be operated in the CW area of the 10 meter band and operated using CW only. Digital QSO Parties should be operated in the digital area of the 10 meter band and operated using Digital modes only (RTTY, PSK, etc).

NOTE: A QUIET ZONE between 28.490 and 28.510 shall be in effect during QSO Parties using the Phone portion of the 10 meter band to allow for others to use the band.

5.2.6 EXCHANGE

10-10 members send call sign, name, 10-10# and QTH (State, Province or Country). If received exchange does not have a 10-10#, then record a zero(0) in the log.

Nashua Area Radio Club Tech License Training Class May 9

The Nashua Area Radio Club is putting together Technician License Training Class starting on May 9 and going for 7 weeks. WE would love to see YL’s join the class. The information on the class is as follows:








The class will cost $35 which includes a copy of the ARRL Technician HAM radio Licensing Manual and a printed copy of the course materials. Pre-registration is required. We will be teaching using the ARRL lesson plan which includes demos and video material to make the class interesting and a great learning experience for new HAMs. We will hold a License testing session at the end of the course so that folks can earn their Technician License. Folks can contact Fred Kemmerer, AB1OC using the information above to register.
