Small steps...

...to the goal to be active on the HF bands are what I´m taking. But I´m in no hurry.

Last week I found someone that sold "a lot of radio equipment". It seemed to be mostly CB equipment but I went there and took a look and see if I would find anything interesting. I stayed there for 2 hours! I had to stop myself from dragging home too much, "maybe good to have" things.

The best thing I bought was a manual tuner from MFJ, 941E. I also got a HT for 70 cm by Kenwood and a scanner AOR AR-1000XLT (seems dead....) and an amp of unknown kind (probably CB) and two SWR meters. I do not have any antenna for 70 cm with BNC connector, so I might try to homebrew something like some of these:

I also received an order from kitsandparts.com . I´m very impressed with their range of stuff, both parts and kits.. ;-) He got building blocks called RF Toolkit so you can add them together to form a transceiver or receiver of different kinds. Really cool.  I will definitely be a returning customer! This is what I got:

The T130-2 toroids I will use together with longwire antennas. The ferrites are for a receiver and good to have in the future. The 30 m LPF I will use with the Genesis Q5 probably in QRSS mode but have to get a 10.140 MHz crystal first. Probably will be from Genesis if I don´t get any other option? The SWR bridge will go together with two ampere panel meters that probably is on it´s way from China right now.Also got 5 NE602 mixers to use with the receiver (more on that later).

During last week I tried to build a dipole, with Slinkys! I really didn´t have any time to evalutate performance (and it was also hanging maybe too low to be a good antenna) but I kept it on receive on the WSPR system.

WSPR receive and flea market

Using the same equipment and QTH as last time I now finally tried the WSPR system that I´ve heard a lot about lately. I only run with receive but I hope to be able to transmit sometime soon. Basically WSPR is a narrow digital mode to be used as a beacon. When you receive and decode a WSPR station, which is done automatically in the software, it uploads the spot to a central database and can be tracked by other users.


Here are a few links to get more information about WSPR:

Here are the 2 most noteworthy catches in terms of power and distance:

G4PEC 30m 0.001W 1060km

RA9CUA 17m 2W 2710km

This weekend I also went to some flea markets to look for interesting equipment. I came home with these things:

2 Valve radios that of course included variable capacitors, an old box with big variable resistors, some kind of alarm controller (atleast a box for other project) and an equalizer. Also got some telescopic antennas and cables (twin lead and speaker cable). I didn´t pay much, so I think it was a bargain!
