Description

MicroHAM USB Interface II includes full optical isolation of all control signals (radio control, CW, PTT and Squelch) and high quality audio isolation transformers with level trimmers (screwdriver adjust) to permit connecting a computer sound card to your radio's rear panel audio input and constant level audio output for use with digital mode software or echolink. MicroHAM USB Interfaces have built-in hardware support for your radio - you no longer need additional level converters like CT-62, IF-232, FIF-232, CT-17.  The drivers include support for software CW keying (DTR) and PTT (RTS) - there is no need for additional keying interfaces.

The interface is suitable for connecting any type of transceiver that has a CAT port. For example, Yaesu, Kenwood, Icom, Elecraft, Ten-Tec.

MicroHAM USB Interface II box contains: device, USB A/B cable, clip on ferrit rfi filter

The device is compatible with a wide range of radios, so you need to create a radio-specific cable, it is not supplied in the box. If necessary, we can manufacture these cables and you can ask for our unique quotation! Cabling and device setup can be downloaded here: http://www.microham.com/contents/en-us/d137.html

RTLSDR through the eyes of an SWL observer over the past 8-10 years

SDR radio became popular in Hungary around 2012-2013 thanks to the RTL chip versions appearing among DVB-T Chinese USB TV receivers. Back then you couldn’t get these devices in Hungary, you had to order them from China. Since then the situation has changed a lot here, too.

Introducing the new 5W Dual Band Digital Transceiver – Yaesu FT3DE!

The new Yaesu FT3DE provides reliable 5W RF power output in compact design and light weight from factor - W62mm x H100mm x D32.5mm/ 282g. Battery power-saving settings are available for each frequency band with TX output power level (5W/ 2.5W/ 1W/ 0.3W) individually selectable. Even in a compact body, the user can enjoy loud and clear C4FM voice quality from 700mW of audio power. Real Dual Band Operation (V+V, U+U, V+U, U+V) are available with two independent receivers, and the FT3DR/E supports simultaneous C4FM digital monitoring for both the A and B bands (C4FM/C4FM standby).

SDRplay is pleased to announce the release of SDRuno v1.3. SDRplay is pleased to announce the release of SDRuno v1.3. This is a major upgrade to SDRuno, which adds a number of important new features and is intended for all RSP models (RSP1, RSP1A, RSP2, RSP2pro and RSPduo)
PDN (Portable Digital Node) function for the FTM-400 and FTM-100 We are excited to inform that the PDN (Portable Digital Node) function for the FTM-400 and FTM-100 series is now available. This firmware is now available at Yaesu official website: http://www.yaesu.com
Raspberry Pi 3 + SDRe receivers It is clear that an excellent way to attract newcomers to the radio hobby is via the Raspberry Pi plus an RSP.  SDRplay has made available a downloadable SD Card image which is ideal for this.
