The W6JWS 2-meter Repeater Maintenance and Repair Log documents the ongoing upkeep of a 146.745 MHz repeater, specifically addressing modifications to enhance its functionality. It details changes made to ensure the repeater powers up in _PL mode_ and to improve the reliability of touch-tone control, drawing comparisons to similar work performed on the AE6KE repeater. The log also notes a repair to a fused wire in the reverse battery protection circuit after an accidental polarity reversal, highlighting a temporary workaround where a wire was omitted but the system remained operational. The resource includes practical insights from Jeff Liebermann, AE6KS, regarding jumper configurations and programming, with accompanying photos. It provides access to several documents for the Icom RP-1510 repeater, including operating manuals and a schematic for the single logic board version, which differs from the dual-board configuration described in some printed manuals. The log mentions a specific modification to adjust the dropout delay, which was later deemed unnecessary, and references a related project for the AE6KE repeater, aiming to replicate successful modifications on the W6JWS machine, resulting in improved touch-tone reliability and proper PL mode activation.

The _Icom IC-7300_ transceiver, a popular SDR rig, can be readily configured for digital modes like FT8 using _WSJT-X_ software. This guide details the necessary steps, from downloading the correct version of WSJT-X to configuring the radio's USB audio and CAT control settings. It emphasizes a straightforward approach, aiming to simplify the often complex initial setup for new digital mode operators. K0PIR shares his practical experience, outlining the specific menu settings on the IC-7300, such as USB SEND/DPT and USB MOD LEVEL, which are crucial for proper signal modulation and transmission. The resource also covers the integration of WSJT-X's built-in logging capabilities, streamlining the process of recording digital contacts without needing external logging software immediately. This setup allows for efficient operation on various HF bands. Two embedded videos further illustrate the configuration process, providing visual aids for each step, from initial software installation to making the first FT8 contact. The author's method focuses on minimizing common setup hurdles.

AE6KE Repeater Repair Project Log, Icom IC-RP1510

A 15-pin data switch, typically a rotary-knob type designed for DB-25 connectors, forms the basis for this microphone selector project. The resource details the conversion process, which involves replacing the original DB-25 connectors with **RJ-45** or **RJ-12** jacks to accommodate modern amateur radio microphones. It specifically addresses wiring for radios like the Icom IC-706 series (including the IC-7000 and IC-703) and Yaesu transceivers such as the FT-857, FT-897, FT-817, FT-7800, FT-7900, FT-8800, FT-8900, FTM-100, and FTM-400. The design ensures all microphone lines are switched straight through, with separate contacts for external speaker/headphone jacks, allowing simultaneous switching. The project emphasizes the practical application of switching between a headset for net control and a hand mic for rag-chewing without repeatedly plugging and unplugging cables. It highlights modifications to the original concept, such as eliminating a separate PTT jack by integrating PTT into headset cables and building the external speaker cable directly into the selector. The article provides guidance on managing the non-color-coded wiring often found in these data switches by soldering wires one by one from old to new connectors, ensuring correct pin alignment. This approach simplifies the conversion, making it accessible for hams seeking a functional and cost-effective mic switching solution.

This article is about replacing the LCD display in a Icom IC-756 classic. The displays in these radios have not been supported by Icom in several years.

Icom PW-1 1kw Linear Amplifier described by WA0SXV

DF0WD/DL4YHF's Longwave Overview details amateur radio operations on the 135.7 to 137.8 kHz segment in Germany. The author outlines the "inofficial" European band plan, specifying segments for QRSS, TX tests, beacons, conventional CW, and data modes. Early LF activities at DF0WD began with a 20-watt CW transmitter, later upgraded to a homemade linear transverter capable of 100 watts, driven by an Icom IC706 on 10.137 MHz. The station's antenna system includes a 200-meter wire, approximately 10 meters above ground, supported by football field light-masts. Despite its length, the antenna's efficiency is noted as very low due to the immense wavelength of about 2.2 km. The author's experience highlights the significant challenge of achieving effective radiated power (EIRP) on LF, estimating DF0WD's EIRP at around 80 milliwatts based on field strength measurements from PA0SE. DF0WD/DL4YHF has successfully worked numerous countries on 136 kHz CW, including DL, F, G, GI, GM, GU, GW, HB9, HB0, LX, OE, OH, OK, OM, ON, OZ, PA, and SM. The author also mentions ongoing efforts to log contacts with CT, EI, LA/LG, and to complete a two-way QSO with Italy, demonstrating persistent activity on this challenging band.

Unlike older radios, the 706 uses only one crystal oscillator (called the Master Oscillator). All other frequencies in the radio (L.O., 3-4 I.F. stages, VFO, and CW-offset) are computer-derived from the Master Oscillator. This makes it relatively simple to frequency-align the radio, so that it agrees with the Frequency Display in all modes.
