SOTA Halfwave Tuner

The Hendricks QRP Kits has released the SOTA (Summit On The Air) Halfwave Tuner for the backpacker because it is small to put on your bag.  It weighs only 72 grams. This tuner can cover 40m-15m bands for the halfwave length antenna. The SWR LED indicator shows the simple matching for the antenna. It costs $30.00 plus S&H charge.



This is a good combination with the QRP transceiver when you would like to operate the HF bands with the light-weight opration set which consists of the rig, the antenna and the CW key.

SS-40 40m receiver

Recently I got the SS-40 kit which is the 40m superhetro receiver by K8IQY. The sensitivity (MDS) is -132dBm. and the side band rejection is greater than 50dB.
The kit is offered by the Four State QRP Group and the kit price is $55 for the international delivery.

It is definetly a good combination with the QRP transmitter.

KEM-DDS-MINI

Kida Enigneering Manufacture has just released KEM-DDS-MINI which is the DDS-VFO between 1Hz-160MHz.


The price is 6900JPY with LCD and 6400JPY without LCD. You need to add the shipping and handling charge. The AD9953 is the DDS chip.
It consumes 100mA with 5V and you may use this kit for either 2m and 6m transceiver. I would like to get one to build the 6m DSB (Double Side Band) transceiver.

ALTOIDS PA - CQ Ham Radio - Oct 2009

In the Oct 2009 issue of CQ Ham Radio, JN1GLB, Makoto Kasahara wrote the article of ALTOIDS PA (20w amp for QRP rig in Altoids). It is the same formula with ATS-3B. The article describes that he would make the board with requested people.

The ALTOIDS PA is IRF510 parallel PA with 20w output in HF bands.

KEM-RX3.5 : KEM has been released the 80m receiver.

KEM has released the 80m band receiver (KEM-RX3.5). The receiver is superhetrodyne and IF is 455KHz. It's the same diagram that the 40m band reciever has. The KEM-RX7 for DX orders is $54.87, therefore I assume it will be the same price range.
