Kenwood TS520

This transceiver was an alternative to the Yaesu FT101B in the 70s. Similar in concept, with a transistorised receiver and low power transmitter stages, and 3 tubes in the transmitter, these radios gained a reputation for having very smooth sounding transmitter audio. Kenwood continued this "sound" in later radios, mainly achieved by placing the carrier oscillator frequency closer to the edge of the ssb filter, increasing the low frequency components in the transmitted ssb. The TS520S added the 160m band and an option for an external digital readout, the DG-5. Nominally 100w output from a pair of 6146 tubes.

Revision History

This site is based on a document originally written by Mark Cheeseman VK2XGK with contributions from many Australian radio amateurs. The document was originally a plain text file distributed via the newsgroup and via an FTP server. A full list of contributors appears at Acknowledgements below.

It was updated in November 1995 by Andrew Davis VK1DA. The main reasons for change were the revised amateur licensing structure in Australia introduced in 1995 by the Spectrum Management Authority (now Australian Communications and Media Authority). It was converted to an HTML document and published in that form. Routine major and minor updates have been made since then, one in June 2001 by Peter Parker VK3YE and further updates were made in 2004 to 2006 to cater for the licencing changes resulting from the removal of the morse code test and the review of the Amateur Radio Service by the licencing authority.

The document was moved to VKFAQ.AMPR.ORG with the assistance and generosity of Carl Makin, VK1KCM, in 2004. This enabled it to have a more appropriate persistent URL and not be dependent on an individual ISP account.
