7MHz transmitter - CQ Ham Radio - July 2009

CQ Ham Radio magazine provided the board of 7MHz transmitter at the July 2009 issue. You can get the parts from Marutsu.

Here is the part of 7MHz transmitter that you can buy it here.

The transmitter has 7.000MHz crystal with capacitor, therefore the frequency is shifted to 7.003MHz. The output power is about 200mW. Those two transistors are 2SC1815-BR which are common ones in Japan.

Some of people described that they contacted at the beta version in the magazine. You need to get the receiver to contact. The article shows DE1103 and FT817 for the receiver.

The August 2009 issue shows the 2W amp (2SC2078) for this transmitter.

KEM-RX-HF

The KEM is selling the HF receiver called the KEM-RX-HF for 1.9MH-21MHz. The price is $57.17. The IF frequency is 4MHz and 4-pole crystal filter. The original parts are included for 7MHz/40m band and you can change the frequency with the parts.
Since there is no VFO, you need to get the VFO to generate the signal to convert to IF 4MHz.
I've got the KEM-DDS-VFO to connect the KEM-RX-HF for 7MHz receiver. The price of this VFO is $70.96.

The KEM can accept the DX order on this page. You can pay it via the paypal.
