OK, so I’m not the first to add 17m to the Hustler 4/5-BTV antenna. In fact you can pay for a factory made version if you wish. Personally, I believe in experimentation and a bit of homebrewing.
The MC-60 desk microphone by Kenwood is a high quality item. This microphone also has a built in pre amplifier which can be powered either by batteries, or by power fed from the radio.
Kenwood TS-850 Memory Loss
Because of the age of the design and components used, the circuit uses a RAM chip. Using RAM has a drawback in that it requires power to retain information. This power is supplied from a small memory backup battery. Modern designs use NVRAM (Non-Volatile RAM) which retain the information without requiring power.
Most owners of this radio would agree that the Kenwood TS-850 is a very good radio except for the noise blanker.
When operating on CW the monitor volume is at a fixed level. This level is set by a preset inside the radio’s bottom cover.
How I modified the Yaesu FT-747 to incorporate an internal USB soundcard to allow it’s use on digital modes. The modification has a minor downside, this being that the microphone is open while transmitting signals via the USB soundcard. The only way around this problem without building an audio switching circuit is to remove the microphone from the radio.
This post described the method used to change the standard Yaesu FT7800/7900 amber display colour to white. Of course, any other colour, or mixture of colours may be used depending on personal preference.
The Yaesu VX6-R hand held transceiver is shipped in the UK with standard transmission capability on both the 2m (144-146MHZ) and 70cm (430-440MHz) bands. Depending on the country of sale, it can also transmit between 222-225Mhz.
