This is a portable, all mode, low-power transceiver with many great functions; all of which are listed here in the manual.
go site Transmitting from my Lake Monroe Indiana campsite easily across the continent and beyond on just 5 watts of power, which is about the equivalent of most HT(handy talky) portable handheld transceivers in terms of power usage. Speaking of reduced power, a Raspberry Pi computer uses about 2 watts! Compare that to the next generation game consoles that were just released the Xbox One and PlayStation4 vary anywhere between 70 and 140 watts during operation.
get link Similar to txt’ing on modern mobile phones, ham radio also has codes that inherit a lot from the Morse Code days. There is a list of Q Codes which are predefined terms essentially creating a short hand for messaging, these are a few that I have picked up just from listening to local repeater stations.
- QRP = Reduced power. (typically under 5 or even 10 watts)
- QSO = Contact successful between two stations.
- QSL = Can you acknowledge receipt?
- QSY = Changing frequency.
- QRM = Picking up man-made interference.
- QRZ = Who is calling me?
- QTH = My location is…
enter site All was made possible by an end fed multi-bander so called since the feed point for the antenna is at one end of the dipole. This allows the antenna to be draped straight off a ledge or in my case strung up close to 90 degrees vertically, the ideal angle for long distance communications to other continents around the world.

Some of the contacts I had made they were using 1,000 watts compared to just 5 watts on my HF rig!
الخيارات الثنائية نيوزيلندي There was some very rare DX(long distance) in the middle of Atlantic Island I heard, but there was too many transmissions at once created a large pile-up making it difficult to initiate contact especially with my reduced transmission power relative to others.
PZ الخيارات الثنائية تحميل Logging my QSO’s on paper was old school and fun but there is also a nice iOS application that I used on my tablet that links contacts directly to www.QRZ.com. Pulling up user’s profiles shows the QTH of the contacts you make and logs them. I’ve even seen some people that link to a live webcam stream of their shack showcasing their rig and equipment while transmitting on the air.

It’s so thin and narrow you can fit about 20 simultaneous PSK-31 transmissions in the same amount of bandwidth that would occupy one voice SSB transmission of roughly 2.5Khz wide. This method of operation requires a computer to decode the audible tones that cannot be deciphered by human ear alone. With the useful Android app DroidPSK I was able to simply reach into my pocket and use my phone to decode the signals I was hearing.

Here is more on the atmosphere explained in great detail for sky wave propagation which signals have MUF(maximum usable frequency) that will bounce off the ionosphere going even further at night since the D-Layer aka day time layer are gone at night exposing the F-Layer for longer distances.
