Stamford Amateur Radio Association Repeater Club. Located in Stamford, Connecticut.

The Eastman Amateur Radio Club (VE4TG) operates a **VHF repeater** at 146.73 MHz and a **UHF repeater** at 444.15 MHz, both located at the Manitoba Hydro gas-fired generating station near Selkirk. These repeaters are situated on the power plant roof, leveraging its infrastructure for antenna placement. The club's primary objective is to offer a reliable local repeater site for members in the East Selkirk and Lockport areas, ensuring consistent amateur radio access. Beyond routine communication, the club maintains a standby communications link to assist local municipal authorities during emergencies requiring communications support. The unique repeater site location at a generating station provides a robust backup power supply, enhancing reliability. The club also organizes activities such as a weekly net and participates in WARC Field Day, fostering community engagement and operational readiness.

The P4 Aruba Callbook, last updated in 2010, serves as a directory for amateur radio operators active from the Caribbean island of Aruba. It meticulously categorizes P4 callsigns into several types: **P41-** for special resident calls valid for one month, **P43-** for permanent resident calls renewable annually, **P49-** for permanent visitor calls also renewable annually, and **P40-** for temporary visitor calls valid for one month, often used in contests. The resource notes that obtaining a permanent visitor callsign requires passing a local examination. The callbook lists numerous specific callsigns, including their QSL routes, operator names, and sometimes addresses or activation dates. For instance, P41A routes via P43A, and P40HQ was used by P43ARC via I2MQP for IARU contests. The entries include both active and Silent Key (SK) operators, with dates of passing where known, such as P43ADA (SK, Sep 2014) and P43JB (SK Jan 2012). This detailed listing assists DXers and contesters in verifying contacts and ensuring proper QSLing for Aruba operations.

Developing operational amateur radio equipment for the 134 GHz band presents significant technical challenges, particularly in frequency generation and stability. This resource details the construction of a 134 GHz system, outlining its architecture with separate transmit (Tx) and receive (Rx) modules, each employing a local oscillator (LO) and RF head units. The system utilizes a dual Flann 50 GHz lens-type horn antenna configuration for optimal signal coupling. The transmit path incorporates an LMX2541 synthesizer chip operating at approximately 2.8 GHz, referenced by a 10 MHz double-oven Morion OCXO for exceptional stability. This signal is multiplied through a series of stages (X4, then X2) to generate a 22.4 GHz signal, which subsequently drives a dual series diode multiplier to produce the final X6 signal for 134 GHz operation. The receive side features an anti-parallel diode mixer coupled to a 144 MHz transceiver via a preamplifier, ensuring effective downconversion. Operational mode is CW, achieved by keying a multiplier stage. The project includes images of the Tx and Rx head units and describes a successful 3.5 km test with G8ACE, demonstrating stable signal tones due to PLLs locked to OCXOs at both ends, confirming the system's robust performance.
