Direct Conversion 10-160 TXVR w/DDS 
|
Time owned: 0 to 3 months

The Juma TRX2A is a 10-160 Meter SSB/CW Direct Conversion Transceiver with a DDS VFO and receive coverage from 100 KHz - 30 MHz. It's an all surface mount kit that was a pleasure to build with the best organized kit I've encountered. No confusion over what tiny part is what with their system. It's not a beginners kit but was not difficult to build and it worked correctly at power up.
The DC design here provide a remarkably quiet and sensitive receiver. In fact it hears all that my K3 does. The audio is nice and I've received good reports on tranmit too. The Juma's SCAF filter is adjustable and does an excellent job. Like many radios in this price range, extremely powerful adjacent signals can tend to pump the AGC. Many DDS radios suffer from DDS generated spurs but I only found a minor problem in the 21 MHz band which did not interfere or cause any difficulties during a recent world wide DX CW contest.
The Juma has a simple user interface that make it easy to use and offers some surprising features in such a small package like a RS232 port for PC rig control and logging.
I really like this radio and am having fun using it. Unfortunately the Euro to Dollar exchange rate adds a bit to it's otherwise reasonable price. Maybe an American Vendor will pick up the Juma line someday and make it more afforadable. However, I must say, the results I'm seeing from the TRX2A performance make the price easier to accept.
