|We have just hired a new Contest Branch Manager, who will be getting things back on track shortly. Prior to this point, the Contest Branch was being covered by other staff members, who did their best to keep up while also doing their primary job. Thank you for your patience.
You are always welcome to call ARRL Headquarters and ask for the Contest Branch.

|Collins supplied a specially designed RF interconnecting cable to use with the exciter of the 30L1; typically the KWM-1. This cable was special as it presented 50 ohms to the input circuits at all times.
Also, on another W8JI related topic regarding the 30L1, the AC power cord and transformer have wiring issues that are potentially dangerous. Collins made some serious errors wiring the power transformer. For safety sake, please read the information on the following link to make sure your 30L1 isn't wired in a dangerous manner:
|Tuska 224||KG4AIP||on 1/5/14|
|This is a single tube, AM Broadcast Band Receiver. You will need a six volt battery (or 6 V dc power supply) and 22 to 27 V dc to power the plate. The 9 volt batteries in series works good for that.
You will also need high impedance headphones (2K-3K Ohms), a good antenna and an good ground to make it work.
It uses a four pin 200 type tube, though a 201 type tube can also be used.
