1.3GHz 20W PA

My plan to be QRV on 23cms EME continues to move forward albeit at a rather different pace to what I’d originally envisaged. After a period of many weeks where little progress was made I’ve focussed my mind on getting … Continue reading

1.3GHz Transverter – separate TX / RX ports

The SG-Lab TR1300 transverter continues to impress me. My current setup on 1.3GHz is the TR1300 with Sam, G4DDK’s VLNA and a single 67 element long yagi. The Anglian transverter is used on the 144MHz IF side, both transverters are locked … Continue reading

Constructing another K3NG Rotator Controller

I recently spent a day helping a friend setup his new rotator and single 8 element yagi for EME operation. The weather was kind to us and after a few hours work we had everything aligned as best we could.  This … Continue reading

TrakBox with MAP65 and LP_Bridge

Since I started running MAP65 it has always been run on a separate laptop along with Linrad. This was primarily due to the amount of monitor “real-estate” that was needed for all the various programs that normally run when operating … Continue reading

ZLPLL

I built my 2m transverter with the intention of using it primarily for EME (JT65), driving either my 2m PA or at some point in the future as the IF for one or more microwave transverters. To ensure that I … Continue reading

9 Element DK7ZB

I built this antenna using 1/2 inch diameter tubing for the elements and 1 x 1 inch square tube for the 5M long boom. The photos below were taken at various stages of construction. The driven element was constructed using the following … Continue reading

Sequencer

When I first started my EME tests I was running the TS2000 barefoot and without an LNA so there was no need to worry about using a sequencer. This changed as soon as I installed the LNA. Even though it … Continue reading

Rotator Controller Using Arduino and PstRotator

When I first started my 2M EME experiments elevation and azimuth control of the antenna was done manually, using a “plumb-line” and protractor for elevation and circular protractor for azimuth. The antenna was held in position with “G-clamps”. This system … Continue reading
