The History of W1BST and the LRRA

George “Pete” Hall WA1APL spoke to the Lakes Region Repeater Association at its dinner meeting on September 26, 1998.  In his remarks Pete described the early work of establishing a two-meter FM repeater that would regularly serve Lake Winnipesaukee and the surrounding area.   Here Pete shares with us the notes he used as he addressed the group.

Beginnings of the LRRA

I would like to thank Tom Bates (AA1NZ) and Dan Morgan (W1UR) for inviting me here today to talk with you about the first days of the LRRA and some of the events that evolved.

From 2-Meter AM to FM

Back in the Late 1950’s and early 1960’s, there was a group in the Lakes region that held regular roundtable transmissions on a daily basis using 2 meter AM transmission. This activity became popular, as near as I can tell, by the availability of the Benton Harbor Lunch Boxes manufactured in kit form by HeathKit, Inc. For roughly $50 you could get on two meters. There were no repeaters in those days so anyone on two meters sported some form of beam antenna. Polarization was horizontal so there was relatively no mobile operation on two meters. It wasn’t until the 1970’s that HAM FM repeaters were introduced to the area. The most successful was probably the Concord Repeater under the sponsorship of Ted Everett. Most of the Lakes Region Hams who had 2 meter FM equipment monitored the Concord Repeater at that time.

Conditions of the time – Difficult to get licensed – FCC Requirements – Technology limited.

Saddleback Repeater – Tom Vinton (K1CEU), a technician, had a drive to build repeaters. He was probably the most knowledgeable person in the area regarding the technical requirements of the then current Repeater technology. If there was a mountain top available, Tom wanted to put a repeater there.

Doc Steady W1BST

I personally got involved with 2 meter FM and repeaters through my acquaintance with Tom. Fred (Bing) Miller(W1IIQ) had been a long time friend of mine and he was very active with the Lakes Region Hams on the Concord Repeater and through working Bing I made acquaintances with Doc Steady and his crew. I also worked the Saddleback repeater with Tom, in fact Tom and I both worked for NHN and saw each other almost on a daily basis. Eventually we all got together and Tom heard Doc speculating on a “someday Lakes Region Repeater”. This fit right into Tom’s agenda, and I, as the middleman, became somewhat of a liaison.

The LRRA

It wasn’t long before a meeting was set up between Doc’s crew and Bing, Tom and I. As Tom lived in Dover, we chose middle ground and met in Wolfeboro. Doc and ?, and maybe Pete Steady, all came to Wolfeboro in Doc’s boat and met with Bing, Tom and I at the town docks. We held our meeting right there on a park bench and decided to organize the “Lakes Region Repeater Association”. Doc pledged to advance the association the necessary funds to get started until we could build a membership and set up a dues schedule. The meeting took no more than a half-hour as I remember.

Cotton Mountain

Needless to say, the membership grew to over twenty member’s overnight. A technical committee made up of Tom, myself, Bing and Bob? (WA1KVW) were selected. Bob was a natural choice as he lived on top of CottonMountain, which had a view of almost the entire Lake Winnepesaukee. Needless to say, he also offered his residence and tower as a host site for the repeater. It was decided early on, that a very low power repeater would be constructed. It was felt that with the terrain, as it was in the area, restricted the coverage potential pretty much to the local area around the lake. Low power would (1) be adequate for the area and (2) would eliminate many problems, particularly that of de-sensing the repeater receiver. At this point in time, we planned to use two antennas, one for receiving and one for transmitting. This was before the days that duplexers were readily available. Tests were conducted and it seemed that everyone in the Lakes Region could work Bob at his QTH. There were a few dead spots, but all in all, the coverage seemed to be satisfactory.

From Modified Motorolas to HeathKits

Most repeaters at this point in time were made out of modified commercial two-way radios. Old Motorola and GE 2-Way radios (boat anchors) were very scarce even though most of the tube type gear was being replaced with the new transistor equipment by the public service organizations. The Concord, Saddleback, and Derry Repeaters all used this type of gear. There was no lack of information on how to modify the gear. Practically every issue of QST or CQ magazines carried “how to” articles. At this point in time, there were a lot of operators and few repeaters. The “baby drake”, TR22, one of the more popular ham rigs in use at this time, and because of its low cost (less than $200.00) and six receive and transmit xtal controlled channels and rechargeable nicads, made repeater operation readily available. Heathkit had a very popular rig also.

Early Repeater Licensing and the FCC

Up until this point in time, the FCC was very wary of repeaters. They did not have clear cut rules and were very cautious about giving out repeater licenses. The monitoring requirements by the license holder were very ambiguous and it seemed that every license holder had their own idea regarding them. Some insisted that there had to be someone sitting by a switch and ready to turn the repeater off if a perceived usage was not exactly within the guidelines that they thought to be good amateur practice. Most hams agreed that in order to license a repeater one had to present to the FCC a broadcast license type of presentation. The Saddleback repeater license application consisted of over 50 pages and included propagation studies, graphs, along with detailed descriptions of equipment, antennas, etc. It took weeks of work and considerable amount of technical expertise to prepare one of these applications. At the time the Lakes Region Repeater Association was about to submit a license application, it was generally accepted that this was the route that had to be taken. It was also pretty much the rule that it took about 3 to 6 months to have an application acted upon by the FCC.

License Application

I was the one elected to prepare and submit the application for a license for the Lakes Region Repeater Association. It was agreed that Bob (WA1KVW) would be the designated license holder as the repeater was to be located at his residence. Fred (Bing) Miller(W1IIQ) and myself (WA1APL) were to be designated as control stations. That meant that Bing and I, along with Bob, were the ones to pull the switch if we were to accept the more radical interpretation of the almost non-existent rules and regulations of the FCC. Actually, we didn’t think too much about control at this point, as we were sure the repeater would take about six months to get licensed. This was the average time frame so far.

Enter the ARRL

The ARRL was very much aware of the consternation among the hams and the lack of any realistic guidelines governing all aspects of the relations between the Hams and the FCC. Unknown to us at this time, the ARRL had a man in Washington at this exact time, to discuss the licensing and control requirements for repeaters. Fortunately, of the many repeaters around the country, there had been very few complications and they seem be working very responsibly. The gentleman from the ARRL and the FCC discussed simplified license applications for repeaters but no action had been taken. They even drew up a possible application, which was based on both the ARRL and FCC input. This application was for study by both the ARRL and the FCC. Somehow, and I don’t recall how, we got wind of this meeting. I called the ARRL and happened to get a hold of the gentleman who had just returned fromWashington. He hadn’t even opened his briefcase as yet, but he told me about his experience in Washington and said that the FCC was very receptive to him and his ideas. He told me about the application form they had put together and that it was all very tentative, but suggested as an experiment, why didn’t we try using it. He said he would send me a copy and that I could make reference to the meeting in Washington. A couple days later I received from the ARRL a very abbreviated application form less than one page long. I filled it out, with a cover letter of explanation, and mailed it to the FCC. Two weeks later I got a call from Bob and he told me he just received a repeater license in the name of the LRRA. Needless to say, the next month, I think every Ham publication in the Country had an article about the license that the LRRA got in two weeks. The day we got the license, I called the ARRL and reported to them, and they were astounded and elated. This apparently ended the folderol of repeater license applications.

Building the First LRRA Repeater

Now we were in a dilemma. We had a repeater license but no repeater. We fully expected that we had at least six months to get it all together. We knew we wanted to go low power (1 or 2 watts), we had a Tower to put two antenna’s up, but we hadn’t made any decisions regarding what actual equipment we wanted to use. At the time, there was a company over in NY state called VHF Engineering that put out a line of kits for 2-Meter transmitters and receivers. Tom had built a couple of these units and they appeared to work quite well. They were inexpensive, so if we couldn’t get them to work together using dual antennas as a repeater, it wouldn’t be a financial disaster. We ordered a transmitter and a receiver. I think the total cost was less than $100.00. Tom went to work putting it together. He was super at this type of activity and when he finished, it looked like a commercial rig. We were fortunate, as both Tom and I worked for the NHN; we had good picking from a great deal of discarded commercial equipment and some of the best test gear around. We also had Charlie Tamm as our chief engineer and boss, who was a devoted ham, and who I believe became a member of the LRRA.

Antenna Up, and Running

Now we had a location, and a repeater, but we didn’t as yet have nor had we decided upon an antenna pair for the repeater. Andy Nuttle(), a member of the association came to our rescue. Andy owned the GAM Antenna Co. in Manchester, where he manufactured his antennas in an old abandoned mill (which subsequently burned down). His antennas were popular with the Hams around the country and several cities used them for their police communications. The popular television series of the day, “Hawaii 50” sported GAM antennas on their police cars. Andy had a base station antenna design, which he said he could make up for us and donate to the club. Sure enough, he came through with a pair of antennas and he even helped us mount them on the tower. That evening, we got on the air and surprisingly; we had very little desensitizing, which was the plague of dual antenna repeater installations. Before we finished that night, I bet we had twenty people sign on. If memory serves me correct, I believe Doc Steady was the first station to call in.

WR1ADX Begins with the First Beep

There was a lot of activity at this time. All of the existing repeaters were busy most of the time. WR1ADX (LRRA Call sign) was no exception. Even though it was only one watt, there must have been 35 or 40 regulars on and there was seldom a time when you couldn’t raise someone. Keeping in mind that the existence of repeaters, and all of ham radio, for that matter, was to provide service in an emergency. There were no cell phones at this time, so there was an obvious need for some kind of reliable mobile communications. This fed the popularity of repeaters and their support and provided a challenge to all of the hams using the repeater. In my experience, hams are very much aware of this responsibility, and were generally on the lookout for someone who might be in trouble on the roadside and need help. Hardly a day went by when there wasn’t at least one “911” call by one of the hams on the repeater. In order of facilitate this emergency need, the “beep” was introduced. As far as I know, this repeater was the first in the country to have this feature. In practice, when an operator turns over transmission to another operator, there is a tail on the repeater when it is released before the repeater drops out. There were timers built into the control systems of repeaters that timed out a transmission if someone was too long winded or captured the repeater before the tail dropped out. Very few operators can say they never timed out a repeater. If one came back on a transmission too quickly, the timer would not reset and subsequently the time left would be the accumulated time between the previous transmission and the current one. Timers were usually set around two minutes, which was long enough for a single transmission but rarely long enough for two transmissions. By setting the timer a few seconds into the tail, this forced a period of time for someone with an emergency, or for that matter someone to break in for any reason. Operators quickly learned that this was borrowed time and if they wanted to make a transmission, such as in a round table, they had better wait until the timer was reset. The beep indicated the resetting of the timer. To my knowledge, this feature was first introduced on this repeater. It is a feature that has been copied throughout the country. In fact, the control system, which was designed and built by the technical committee, was replicated and used in several other computers throughout New England.

Duplexers

Whenever a repeater operates on two antennas, there is always a discrepancy. There are spots that you can hear the repeater but can’t get in, or you can get in but you can’t hear the repeater. Also, though we were pleased with the operation of our one watt repeater, it soon became obvious that it really didn’t serve the mobile operators very well, as there were many dead spots throughout the region. After a couple of months, we had pretty much decided that we should up the power. We also decided that we should get a hold of a duplexer and go to a single antenna. The repeater was easy. Standard Communications had come out with a very nice package of a self-contained ten watt repeater. We had a good healthy membership and had no trouble raising the funds to purchase the Standard Repeater.

Duplexers were another problem. There were no commercial duplexers available in the market at this time for ham repeaters. There were commercial duplexers out there but the cost was prohibitive. Tom Vinton had a friend in Vermont that had built a duplexer which was installed on the Mt. Ascutney repeater and worked quite well. This was a four-cavity duplexer called a hybrid ring configuration. Tom’s friend provided us with instructions on how to build one and we proceeded to scrounge around for materials. What would we use for the cavities? When Tom first went to work for the New Hampshire Network, he was the transmitter operator at the Network Hanover Station. Apparently, when the station was first constructed, a section of hard line transmission tubing, six inch copper tubing with a center conductor, was damaged. The installers just left the damaged hard line out in the woods near the tower. This would be perfect material for building the cavities. Charlie Tamm told us we could have it. We salvaged enough material to make two complete duplexers of four cavities, each approximately 2 ½ feet tall. One set went to the Saddleback repeater, which was Tom’s repeater, and we got the other set. Bing Miller (W1IIQ) was instrumental in doing the precision machine work, Doc Steady’s son was instrumental in acquiring some very special rod material that had an almost zero expansion/contraction characteristic for the tuning rods and in a matter of a few weeks we were in business. They were not easy to tune. We were fortunate that we had the use of a very fine spectrum analyzer and some super test equipment complements of Channel 11. They worked beautifully. We were amazed that we had absolutely zero desensing.

A Tower and a Shed

Shortly after the completion of the duplexes, we learned that Bob Thomas, our host, was going to be moving out of the area. Don MacBeth, who lived in the same area as Bob, with an equally desirable site, offered us the opportunity to put the repeater at his residence. This meant we had to find a tower and some sort of a building to house the repeater. Again, through the generosity of many members of the association, we were able to assemble about sixty feet of Rohn tower. We also purchased a tool shed that was very adequate for our needs. A couple of Saturdays and all kinds of assistance from the membership, we were able to install the shack, equipment, raise the tower, run electrical power, and get on the air.

Tech’s Call Sign and a Laconia Site

It wasn’t long after this that the FCC changed it licensing requirements and repeaters used the call signs of the tech that maintained them. Also, my work assignments changed, and I became unavailable to help out on the tech committee. Roughly around this time, a decision was made to move the repeater again, this time to the Laconia area, where some tech people were more readily available. Also, the majority of the membership was from theLaconia area, and moving the repeater there would definitely serve the majority of the membership better. I was not involved at all at this time, but the repeater was successfully moved and remained in that area for some time.
