 RADIOHF - KIWA MAP Synchronous Detector Speaker 
- KIWA MAP external synchronous detector and speaker in excellent cosmetic and operating condition. Adds synch AM detection to most any general coverage receiver with 455 kHz IF output jack. The MAP provides low distortion reception with IF filtering (bandwidth of 6.9 and 2.9 kHz at -6dB), along with a unique Tone Tilt control and an adjustable Low Pass filter. The inventor claims that this ‘Synchrophase’ type detector offers true synchronous detection and that this circuit has been improved by KIWA using a process of carrier regeneration feedback. It is designed for low level signal detection to improve reception during periods of selective carrier fading or when the carrier is subject to noise. Can be used as an external speaker with a receiver's audio output providing rich clear sound. Sold "as-is" and sale final. No warranty is either expressed or implied. No returns or refunds. Sells and ships to continental USA residents only. $850 plus shipping; payable by USPS money order only.

- RADIOHF - Kenwood TS 820S
- Very, nice, smoke free and functional, Classic Kenwood TS 820S Transceiver. . Everything is working fine, minus the digital display. The Display is working but its not matching up with the analog VFO. I'm told that's a common issue with the 820 and a relatively easy fix but it might be a somewhat labor intensive. The rig is in excellent cosmetic condition. This will come with OEM AC Power Cord and Manual as pictured. I will sell, pack, ship and insure all that you see pictured for $275 plus actual shipping to your QTH. If you can pick this up the Denver, CO Metro Area the price would be $250. Keep in mind that this rig weights about 40 Lbs. NO charge for packing materials or my time and effort to very securely pack this radio. I can take PayPal but will hold this in your name for one week if you would prefer to use a Postal Money Order. I have a lot of Hi-Res Pics and can provide them upon an email request. Good on QRZ Thanks for looking. KDØYX
