Pittsburgh, PA and Cincinnati, OH
The June 30, 1942 FCC Annual Report states, "Public hearings were held on applications for construction permits for similar new coastal harbor stations at Pittsburgh, Pa. ---." The FCC Annual Report dated June 30, 1946 indicated that a new coastal Harbor station had been established (authorized?) during the fiscal year at Pittsburgh, PA. However, Jack Estes reports that Warner and Tamble (WJG) obtained a license for a station at Pittsburgh in the 1940s, but took no action to put it on the air and about 1950 relinquished it in favor of RMCA. The 1951 FCC Annual Report states: "Public coast stations were authorized at Pittsburgh, Pa., and --- ." The station was constructed started in the summer or fall of 1950 and completed during the 1950-51 winter. This 1951 RMCA ad mentions WCM as a new station. Since WCM was an RCA station it had a maritime tradition and all messages intended for everyone to read were titled, "All Hands."
Over the years WCM had three owners: RMCA from 1951 to 1967, Ray Gartman (Owner of high-seas station WLO, Mobile, AL and also of WGK, St. Louis, and WJG Memphis for a time) from 1967 to 1974, and Midland Enterprises (parent of the Ohio River Company, ORCO, one of WCM's major customers) from 1974 to 1995. The 1971, and later, ATT Maps show Gartman as the WCM owner.
WCM - PITTSBURGH
This Ship-to-Shore station, located about 17 airline miles southeast of the city of Pittsburgh, was originally installed and owned by RCA's Radiomarine Corporation of America. The builder of the station and its manager during many of the RCA years was William N. Hayton. Through the courtesy of ex-WCM operator Gary Hummell, N3YEX, who had the foresight to save some of the nostalgic items from the WCM Pittsburgh files on the station's last day of operation there on April 15, 1983, we have a great series of photos showing WCM's beginnings. Many of these photos are dated July 1951, but since many show snow on the ground and the trees are bare some were obviously taken the winter before.

following AM equipment:
Transmitters: Main TX was a Wilcox Model 96C (shown above). It had two 450-TLs modulated by two 450-TLs. There was a RF deck for each MHz range (2, 4, 6 and 8 Mhz) and each deck had its own pair of 450-TL tubes. The modulator and power supply (on the left end) were common. The Stand By TX (shown on the WCM Photo Page) was a Model TDF (Made by RCA?). It used a pair of 813s modulated by a pair of 813s.
Receivers: Fixed-channel units (8) by either RCA or Technical Material Co. (TMC) to cover two 2 MHz, two 4 Mhz, two 6 MHz and one 8MHZ channels with one spare unit. The RCA and TMC receivers were similar with plug-in (from the front panel) rf/oscillator sections so the unit's channel could easily be changed by changing the heads. Console tunable receivers: RCA AR 88 and Hammarlund SP-600JX. In the 1951 pictures there is a rack of 5 receivers of an earlier vintage, and the tunable receiver on the table appears to be a National NC-183.
Antennas: A multi-frequency tuned 84 foot vertical which is shown in many of the photos. Flat top dipoles for 4 and 6 and 8 MHz. These must have been installed after the initial construction as they don't show in any of the 1950-51 photos. There was a long-wire (400 Ft) receiving only antenna (which may be the antenna between the 2 telephone poles in the photos?)
Most station control and switching units were "home-brewed" by WCM operators.
In June 1955, the SSE-l was installed on board the M/V VALVOLINE, a river tow boat, owned and operated by the Ashland Oil and Refining Company. C. E. Schneider of Radiomarine operated the equipment on the vessel during a run on the Ohio River between Ashland, Ky. and Mt. Vernon, Ind. Traffic was worked through station WCM in Pittsburgh. The SSE·l consistently outperformed the 150-watt transmitter at WCM and under conditions of interference and atmospherics outperformed the 1000· watt station transmitter. The absence of selective fading effects with accompanying distortion of the received signal'was especially gratifying when using single sideband. The SSE· 1 operated very satisfactorily under the heavy vibration conditions present on board the diesel-driven VALVOLINE. Frequency stability proved excellent, with no distortion evident due to drift effects.
During the RCA years there was a pink RCA form that was used for all messages going to the boats, and another, almost identical pale yellow one, for the ship-to-shore messages. Probably these were generic forms that were used at all RCA stations. At WCM they were kept for all communications and sent to RCA in New York at the end of the month for billing. The outgoing forms actually had the complete text of the message. The incoming ones were gernerated during the scheduled communications with the boats and contained only the vessels position at the time of the communication. All positions were given in the following form; for example: 473 North Ohio or 473 NO. This meant the boat was at 473 river miles from Pittsburgh (mile zero on the Ohio) and was heading upstream. On the rivers upstream is North and downstream is South. It has nothing to do with compass direction. On incoming messages the signature was always "Master". This was probably another high-seas carryover as the top guy on a towboat is usually referred to as "Captain".
When Ray Gartman purchased the station in 1967 Hayton and two of the operators left to take other positions with RCA. Two other crew members managed the station before Frank Deedrick became manager in 1968. Under Gartman's ownership the conversion to Single Sideband (SSB) started. For a few years during the changeover WCM operated both AM and SSB - the existing AM equipment, along with various sideband units under test.
In 1974 Gartman announced that WCM was for
sale and that if there were no buyer the station would be
closed. There was no outside interest in the
station. A partnership was formed by Deedrick, and operators
Lindquist and Kelly to try to buy the station.
However, the others soon opted out leaving Deedrick as the only one
interested. He soon found an "outside" partner in Merlin J.
Pitts. Pitts was not a real outsider since he had been a
marine radio/radar repair person for many years. However, at
this time the FCC required that the station immediately finish
converting to SSB. The additional SSB conversion costs caused
Deedrick and Pitts to abandon the purchase attempt.
Enter, Cincinnati based river transportation company, Midland Enterprises owner of WCM’s biggest customer the Ohio River Company (ORCO). In addition to the ORCO traffic, WCM handled the traffic for all of Midland's other subsidiary companies (also for Dravo-Mechling and Ashland Oil). Since WCM was important to Midland, and since they did not want to find another form of communications, they decided to buy the station and continue operating it as a public correspondence station. The purchase was made in 1974, and the conversion to SSB was finished under Midland ownership.
At that time the technical lineup was Northern Radio Co. transceivers for each channel and 3 switchable Northern Radio linear Amps. The monitor receivers were Communications Associated Inc. (CAI) for each channel. Additionally, the vertical antenna was replaced with a Hy Gain 6 to 30 MHz. seventeen element rotatable log-periodic array on a 75 ft. tower. As with the earlier AM installation, all switching consoles were "home-brewed" by WCM personnel.
WCM also operated a VHF-FM public-correspondence marine station using GE Mastr Pro line equipment on channels 16 and 26. The down-river range was increased by adding remotely-controlled station KLU-836 at Freedom, PA (Ohio River Mile 23.5 - near the most northern point on the Ohio River) also on channel 16 and 26.
Frank Deedrick Repairing Equipment
After the 1974 purchase operation continued at the Pittsburgh location for about 9 years with Frank Deedrick managing in the early years, and Tony Garofalo coming on board as manager in 1979 when Deedrick left. The station maintained a 24 hour daily schedule every day of the year, and used this message format . There were 2 daytime operators (and a clerk-operator on weekdays) and 2 operators splitting the evening and overnight hours. The photos above are from a 1975 newspaper article which gives more information about the station at that time. Also in 1975 Associate, the company magazine of Eastern Gas & Fuel Associates, the parent of Midland, carried a three page color pictorial article about the station's operations. Page 1 - Page 2 - and Page 3 are full-size images of the article.
In 1982 the advantages of co-location with Midland's main office and of Cincinnati's more central location which offered better coverage of all of the inland rivers, particularly the lower Mississippi, prompted a decision to move the station to Cincinnati. FCC permission was requested and received, and the move was made in 1983. Pittsburgh went quiet and Cincinnati came alive at 23:00 on April 15, 1983. When WCM moved to Cincinnati the Pittsburgh and Freedom, PA VHF-FM operations were maintained for a few months and then sold to another VHF marine station operator.
WCM - CINCINNATI
The new Cincinnati station was built by personnel from ITT-Mackay Marine, and Chuck Reynolds provides some detail in his recollections. The new station utilized extensive redundancy to help assure reliable operation. There were 2 main control consoles located at Midland's headquarters on the 14th floor at 580 Walnut Street in downtown Cincinnati (Ohio River Mile 470.4). Six leased telephone lines connected the control point with the remote receiving and transmitting equipment on a two acre site in Withamsville, OH some 15 airline miles to the east. The station listened for calls simultaneously on channels 4, 6, 8, 12 and 16 via a rooftop antenna (just one? and what type?) and 5 CAI crystal controlled monitor receivers at the Walnut Street location. There was also an ICOM R71-A tunable receiver used as a backup for any malfunctioning CAI receiver. There was no transmitter at the Walnut St. site, and all transmissions were made, one frequency at a time, from the Withamsville site. To protect the equipment one set was completely shut down during thunderstorms. Also see this 1992 WCM QSL letter for more information about the station.
Except for Tony Garofalo none of the Pittsburgh staff transferred to Cincinnati. Five new operators were hired, and given 2 weeks intensive training prior to the April 15 switchover. Tony practically lived at the station for 4 months until the new operators became sufficiently proficient. The new WCM became the Communications Center for Midland, integrating the company's Cincinnati HF utility station WXZ354 and their local VHF-FM marine utility station (Call letters?)

WCM maintained two schedules each day at 07:00 and 13:00. The 1992 inland River Record lists 84 Midland boats, and all were contacted at these times. They reported their positions and other pertinent data and received the orders which governed their operation until the next schedule. Additionally, the Dravo-Mechling boats also had a 19:30 schedule just for receiving orders. The text of this 1984 article in Associate, the company magazine of Eastern Gas & Fuel Associates, the parent of Midland, reports on the station operations at it's new Cincinnati location.
With its Midland schedules WCM utilized a list of approximately 70 two-letter codes to speed up communications and simplify the task of entering (typing at the station and handwritten on the boats) the information which was transmitted by voice over the radio channel. It was a very efficient system. Years ago (when I was an active listener to WCM which was the strongest towboat or laker station for me in North Carolina), Tony Garofalo graciously sent me a copy of the WCM code sheet. I rearranged the codes in alphabetical order and combined them with some of WCM's river designator codes that I had obtained by phone from one of the WCM operators late one night. Here's my one-sheet version of those codes.

With new communications options developing, both Ashland oil and Dravo-Mechling eventually made other arrangements for communications services, and after the early 1990s WCM was providing service only to Midland boats. In 1989 Midland started to make some use of the communications services provided by Watercom and also, about this time, began planning to put PCs in the pilot houses with satellite data and voice communications. By 1995 the boats had operational PCs and satellite communications service provided by American Mobile Satellite Corp. This new capability combined with Watercom (which was used until about 2001) and the growing use of cell phones on the towboats led to a decision close WCM rather than move it from 580 Walnut St. to the new Midland headquarters location in the "Book Building." WCM surrendered its license and ceased operation on May 31, 1995,
After WCM went off the air the WCM crew continued operating the Midland Communications Center. Prior to WCM's closing the towboat captains had been furnished with a document detailing alternative communications options and costs including, Satellite, WFN, Watercomm, and VHF public-correspondence marine stations, and much of this communication continued to flow through the Communications Center.
Midland was to last only a few years after the closing of WCM. In 2002 Midland was sold to Ingram Industries (operator of Ingram Barge Line), and during the next two years Midland's operations were integrated into Ingram's, and Midland's Cincinnati headquarters was substantially eliminated with the Communication Center closing on April 11, 2003. Ingram sold off some of the smaller Midland subsidiaries, retained and renamed ORCO's bigger, newer boats and sold the smaller, older boats to other operators. On May 19, 2004 Ingram announced that ORCO would cease to exist.
