Review of the ICOM IC-R9500 Wide Band DSP Receiver

Modifying the ICOM IC-756 Standard (non-Pro model) for 60m takes a little work, but it is worth the effort.

This article describes the construction of a simple dual-band VHF/UHF end-fed vertical dipole antenna designed for local repeater access using an Icom IC-705 radio. Built from a single piece of RG58U coaxial cable, the antenna consists of a 460mm exposed inner conductor, 450mm of intact coax, and a 9-turn choke balun wound on a 27mm former. Mounted on a 10m Spiderpole, the antenna achieves excellent SWR readings (<1.2:1 on 2m, <1.5:1 on 70cm) and provides effective coverage of local repeaters with unexpected reach into distant locations.

Without any doubt at all, the best radio I have owned is the ICOM IC-7610. But the grass is always greener and so even though I loved my IC-7610, I thought there might be something better out there. I purchased a YAESU FT-DX101D and really disliked it.

The ICOM IC-705 remains a standout portable transceiver after 3.5 years of use. Its unmatched feature set includes multi-band/mode support, built-in WiFi, GPS, remote operation, and excellent third-party app integration, making it versatile and user-friendly. Despite competition like the Elecraft KX3 and Yaesu FT818, the IC-705 excels in flexibility, durability, and ease of use. Whether for QRP operations, digital modes, or SSB, it delivers exceptional performance in diverse settings, reaffirming its status as the best portable transceiver on the market.

The article "Icom IC7300 RTC Fix" details the meticulous repair of an Icom IC-7300's faulty real-time clock (RTC). The author and a friend, Nacho, discovered the RTC was gaining an unacceptable 11 seconds per day. Investigations revealed the Seiko Epson RX8803LC RTC was far outside its specified stability. Despite replacing the RTC and a burned pullup resistor, the transceiver still malfunctioned, leading to the replacement of the processor. Post-repair, the clock's accuracy improved significantly, now gaining only 1.4 seconds per month. This narrative underscores the complexities of electronic repairs and the satisfaction of resolving intricate issues.

The international SWL Contest is oen to SWL all over the world. You can use a real radio receiver or a kiwi or web SDR. We have many sponsors who will give nice gift for best listeners of AM radios on SW and MW.

In 2024 the goal of the SWL contest will be to listen maximum of AM radio station on shortwave bands. Awards for all the participants. 73 de Frank SWL F14368

After years of reliable performance, a 26-year-old Icom 706MK2G exhibited an unusual deviation during FM transmission, with the actual frequency being 10kHz off from the displayed frequency. Additionally, the power meter showed a sharp dip during transmission. Upon investigation, it was discovered that the FM VCO voltage adjust variable had become dirty and sluggish over time. By adjusting the variable capacitor and cleaning it with switch cleaner, the issue was resolved, restoring stable power output and accurate frequency transmission.

The Icom IC-7851 features the capability to display two scopes simultaneously, providing frequency, mode, and antenna information for each receiver. Users can choose between vertical or horizontal display orientations, and the dual scopes are also viewable on a high-resolution monitor connected to the radio. Additionally, the IC-7851 allows for mouse connectivity, enabling users to click on signals displayed on either scope for quick tuning. A demonstration video is available showcasing this dual scope functionality.
