41 Band Pass Filters & Amplifi er Accessories RF Vacuum Tubes For special RF power replacement vacuum tubes to fix a current amplifier, revive a legacy model, or build a new one, choose Penta Laboratories. Penta tubes are burned in for a minimum of 48 hours, dissipating full power with filament, plate, and screen voltages that are normally used in amp applications. This ensures electrical parameters are stable and will perform as expected during their lifetime. Tubes are evaluated on WT-100A original RCA production testers for plate current, screen current, and transconductance.

Here’s an ef ective way to combat its inference. Below 1.7 MHz, the filter hits unwanted signals with over 40 dB of attenuation. And it’s virtually unnoticeable on the HF bands—there’s less than 0.85 dB of loss with a SWR under 1.2:1. The filter is optimized for 50 Ω and installs between your radio and antenna (or amplifier/tuner). It handles 200 watts. DLW-FL1718 AM Broadcast Band Brick-Wall High Pass Filter ........................... $195.00 200W PEP Transmit Band Pass Filters A great choice for contesting and DXpeditions, one for each band transceiver for multi-two or multi-multi operations, these precisely craf ed band pass filters from French manufacturer RF Meca are expertly designed to block all signals outside the target frequency band, minimizing interference to and from adjacent frequency bands, improving transmitted and received signal quality.

This allows, for example, several PAs to be addressed simultaneously with one press of the PTT button. A status LED signals the user that a PTT signal is present. The PTT input as well as the outputs are designed as RCA jacks. Requires 9-15VDC via barrel plug; cable with an open end is included. The assembled board is available individually or in an aluminum enclosure. QRO-PTT4 4-Way Splitter, No Enclosure ...........................................................$76.99 QRO-PTT4BOX 4-Way Splitter, With Enclosure ........................................................$88.99 Transceiver Key Line Splitters and Combiners Choose from three dif erent Key Line Splitters and Combiners for the “ground-on- transmit” amplifier keying line of one or multiple transceivers to key one or more accessories or amplifiers safely, without interaction. They are passive DC-only devices that require no power and provide multiple PTT keying line outputs, inputs or both. All four connectors are female RCA phono. Center conductor grounding to the shield of any one of the PTT IN connector(s) provides the same diode protected center conductor grounding to the shield of the PTT OUT connector(s). For example: • KEYLINE-3 is a splitter for one transceiver to key one amp and two accessories. • 3RIGKEYLINE is a combiner for up to three transceivers to key one amplifier. • KEYLINE-DUAL is a combiner-splitter for two transceivers to key two amplifiers, or one amplifier and one accessory. These devices are really handy when using amateur radio devices that need to “share” a T/R keying line and don’t have a keying line pass-through. Each keying input or output is guarded with a separate 60V 2A Schottky diode, providing ground-on-transmit isolation between each accessory keying line. They keep the load or voltage of any one piece of equipment from af ecting the others. Their voltage and current handling depends upon the rating of the transceiver(s) transistor or relay amplifier keying circuit. Check your transceiver manual for the total voltage and current that it will safely handle. These devices handle keying lines only. Other connections and appropriate amplifier and accessory operation must be considered.
