For those with shortwave receiver or a CB or ham radio with receive frequency coverage of the HF bands, this is a magical night that only happens once a year, and very much worth the beautiful Radiogram QSL you receive!
From the MRHS press release (check out all the frequencies!!):
Each year the MRHS commemorates 12 July 1999, the date on which the supposed last commercial message was sent in the US. On that date we pick up the thread, keep the faith and maintain the traditions of maritime radio communications so that the skills and traditions of all the radiotelegraphers who came before us will be maintained.
While MRHS station KSM is on the air every Saturday, on Night of Nights we originate stations KPH and KFS in addition to KSM. We will joined on the air by KLB, WLO and KKUI. See below for details.
You can participate by listening or by visiting the ex-RCA receive site to see the action in person. If you'd like to operate K6KPH just bring your key. No license required!
Here are the details of the event:
Date: 12 July 2011 Pacific time, 13 July GMT

Professional operators will be at the key and commercial procedures [see below] will be used. But please don't hesitate to call, no matter what your code speed or experience level may be. We look forward to your call.

[Commercial procedures: If you wish to replicate the KPH commercial calling procedure pick your calling frequency and send K6KPH K6KPH K6KPH repeatedly until the operator sends DE. Then send you call and traffic. If you really want to get into it send your call and QSS XXX UP where XXX is the last three digits of your working frequency. For example if you call on 7050 you might send QSS 065 UP. The operator will respond with UP - (dah dit dit dit dah) and listen for you on your working frequency while continuing to transmit on 7050. Or the operator may respond with QRX QRY 1 OK? meaning stand by you are number one on the list, which is what KPH did when multiple ships were calling. They stacked up 20 ships or more before starting to work the list. K6KPH typically runs a list of not more than three calling stations. Advisory: On Night of Nights there is often a pileup calling K6KPH which might prevent the above procedure, or you may get a guest operator who will not understand QSS. In those situations just make a normal contact using amateur procedures.]

Remember, this is a public event. If you are in the area you are invited to join us at the RCA receive site, 17400 Sir Francis Drake Blvd in the Point Reyes National Seashore north of San Francisco. If using a computer mapping program add "Inverness" after the address above even though the station is well beyond that town.
Doors open at 3:00pm Pacific time. Snacks will be served. Tours of the transmitting station may be arranged for "true believers" by appointment only.
