I have totally run out of room and need to send my HQ-129-x off to a good home. It is in good physical and excellent electrical condition. Here are the particulars:
• Cabinet; good, a few minor nicks, scratches and blemishes.
• Front panel; good, a few minor scratches. Some black crackle paint is missing at the top of the brass dial escutcheon. Small hole was added to panel by a previous owner; covered with a gray snap-in plug. Panel lettering is perfect.
• Both dial windows (with vertical cursor lines) have scratches which somewhat impede dial reading on some bands. Right-hand window has a partial crack; not seen when receiver is on, does not impede dial reading. No flaws noticed on the large round dials that have the frequency markings.
• Receiver performance; excellent.
Test results, January 15, 2016.
• Sensitivity, normal bandwidth, CW, MDS; freq, dBm: 1.830, -123; 3.6, -127; 7.1, -125; 14.1, -126; 21.1, -124; 28.1, -122. Excellent.
• Sensitivity, xtal selectivity 5: 7.025, -140; 28.050, -137. Excellent.
• The crystal filter has been aligned and is very effective for single-signal CW reception.
• Dial calibration. Very good, remarkably close 25 years after alignment.
• AM test, 3880 kHz, 50 µV, 60% modulated at 1000 Hz, AF output into 8 ohms, distortion measured results: 2 W output, 2.7% THD; 50 mW output, 1.4% THD. Excellent.
Modifications in 2004.
• MUTE mod. Original mute arrangement requires connection to B+ line at inconvenient special tip jacks. This modification added a relay, and a phono jack at rear of chassis. Connecting jack to ground mutes receiver. The open-circuit voltage at the PTT jack is +12 VDC; closed current is 30 mA. With no connection to the new phono jack, the receiver operates normally. The panel standby switch and the original mute jacks remain functional.
• Replaced antenna terminal with a high-quality phono jack; this is now the sole input connection, unbalanced. The other antenna terminals are grounded, and may be used as grounding terminals.
• Added phono jack for speaker. Original speaker terminals remain usable.
• New three conductor AC line cord for safety.
This is a very well maintained and nicely modified HQ-129-x. Price is $195 plus shipping. It weighs about 60 pounds. PayPal preferred.
Due to its age, radio is sold as-is, no returns, no refunds. If interested, please email me for more pictures and information: ai6ii at arrl dot net. 73 ..mike AI6II
