Radio Panadapter project

 I recently came across a panadapter buffer board designed by G4HUP  (http://www.g4hup.com) and decided that it would be a really nifty feature to be able to have a visual representation the signals adjacent to the tuned frequency.

Thanks to a fellow ham who did the soldering for me (THANKS W8VFR!), I now have the board installed and functional.

Basically, we tapped the radio's IF (at very high impendence, so as to not affect the main receiver sensitivity).  Then this signal is amplified about 1dB, then output to an SMA connector installed in the rear of the radio.  Finally, we connect the buffer board's output to an RTL-SDR USB stick, which interfaces to a modified android device running an app called "RF Analyzer".

The total cost of the project is around $100:  Android device:  $50, RTL-SDR USB stick:  $15, G4HUP buffer board $35, homebrew USB interface cable $0.

The result is a fully functional spectrum analyzer / waterfall display connected to the radio's IF.  This gives me a 30-KHz wide view of the spectrum.  I can see 15Khz on either side of the tuned frequency.

My particular radio has a common IF for all bands (160m - 70cm), so the panadapter works no matter which frequency I'm tuned to.

This is a really neat project, and I feel that I've added alot of value to my Yaesu FT-897d.  This could be VERY useful on field day - use your imagination :)

Attached is a picture of the PAT board installed inside the radio, and also a picture of the panadapter in action on 40m.

 

Enjoy!!!!

Packet Radio

 I have recently wth the help of Buster KG9ND, gotten my packet station up and running. 

It has been fun getting setup and testing.  

Believe it or not there is packet traffic around Wayen County, IN.

QST Magazines dating back to 1947

 Alan Weber KC9JWO has informed me that the Anderson radio club has multiple copies of the QST Magazine dating back to 1947 available. They are looking for someone interested to take them as they are moving and don't have the space. If you are interested, please contact Alan at kc9jwo@outlook.com.

Thank you!

Dear Fellow Radio Amateurs,

The Russian Digital Radio Club has the honour to invite the radio amateurs
all over the world to participate in the 1st Russian WW MultiMode Contest
2014. The objective of the contest is to establish as many contacts as
possible between radio amateurs around the world and radio amateurs in
Russia.

Saturday 15th November till 11:59 UTC on Sunday 16th November, 2014. Types of
modulation: BPSK63, CW, RTTY, SSB. The repeated contacts are permitted on
different bands and different modes providing that a contact will be made not
earlier than in 3 minutes. The output power should not exceed 10 watts on 160
meters and 100 watts on other bands. The operator may change the bands no
more than 10 times within calendar hour (with zero on 59-th minute of each
hour). Only one transmitted signal is permitted at any time. Bands: 160 m, 80
m, 40 m, 20 m, 15 m, 10 m.
