Looks like "HQ" was in keeping with company tradition of model identification which began with the earlier Hammarlund- Roberts kit receivers; HI-Q-6, HI-Q-29, Hi-Q-30 and HI-Q-31 Retrocom Presents the 'History Of Hammarlund' THE HISTORY OF HAMMARLUND The name Hammarlund is one of the most distinguished in the early history of radio in America. The Hammarlund Manufacturing Company ranks among the nation's very oldest producers of radio equipment. Organized in 1910, Hammarlund is one of the hand full of firms in the radio field which has continued in business without interruption down through the years. So pre-eminent were Hammarlund products in the pioneering era of radio that they attained for Hammarlund the ultimate distinction of becoming a part of the language of radio. The early radio enthusiasts, the amateur operators, affectionally referred to Hammarlund products as "Ham" products, and called themselves "Ham" operators, a nickname that is now a part of our living language. Among the long line of firsts introduced by Hammarlund were high-precision variable air capacitors, the first commercial short-wave superhetrodyne receiver, and the first selective calling equipment for two-way mobile radios. The Hammarlund story began in 1882 when Oscar Hammarlund, the Company's founder, came to America from his native home in Stockholm. In Sweden he had been a special tool designer and inspector of electrical instruments for the L. M. Erickson Company, leading instrument manufacturers and originators of the French-type telephone. He came to this country to accept a similar position with the Elgin Watch Company, and at the time was regarded a something of a prodigy in Electrical experimentation although only 22. After four years with Elgin, he joined the Western Electric Company as superintendent of the Chicago plant. ... The Hammarlund Manufacturing Company came into being in 1910, 28 years after Oscar Hammarlund came to America. Hammarlund himself had just turned 50. The first Hammarlund plant was a loft operation on Fulton Street in lower Manhattan, New York City. Here Mr. Hammarlund worked on the development of ideas which had been taking shape in his mind for several years. Among the products he designed here was an armagraph, a code practice machine that employed a rotating disc similar to a phonograph record. ... Nine years later, Oscar Hammarlund and his son, Lloyd, developed the Midline variable capacitor which subsequently became the standard for the industry. The company's pioneering work in the capacitor field quickly made it the leading producer of these vital components, and today Hammarlund capacitors are functioning in radio equipment throughout the free world, and are in use in America's space program. With its experience in design and production of capacitors and coils, Hammarlund was among the first manufacturers to supply do-it-yourself kits to the growing numbers Of hobbyists fascinated with radio and wanting to build their own sets. The first Hammarlund-Roberts radio receiver kits Were place on the market in 1925 and found almost immediate acceptance. Not only were the kits purchased by hobbyists, but they were also sold to custom radio builders who resold them as ready-to-use radio sets. The first kit produced by Hammarlund was the HI-Q-6, a model which many old-timers in radio remember well. Later models included the HI-Q-29, Hi-Q-30 and HI-Q-31. By 1931 when the depression was developing and the Market for kits began to diminish, Hammarlund moved aggressively into the ready-made radio field. Wisely declining to cater to a price-conscious market, Hammarlund instead concentrated on highest quality, custom units. ... In addition to Super-Pro receivers and capacitors, Hammarlund produced radar and electronic counter-measures equipment for the armed forces. The war years saw Hammarlund devoting all of its productive capacity to the military effort. In addition to turning out some 40,000 receivers for the armed forces, Hammarlund also built special equipment such as the SX or Navy Search Radar installed on big carriers, battleships and cruisers, and "jamming" equipment for blotting out enemy radio transmissions. Shortly after the war, the market was flooded with surplus Super-Pro receivers at bargain prices. Notwithstanding competition from its own brand of receivers, Hammarlund quickly introduced the HQ-129 receiver for the radio amateur market. This was followed in 1947 by the SP-600 receiver which, remarkably even surpassed the Super-Pro in flexibility and performance. They were quickly selling at a rate of about 5000 sets per year, in spite of their high price. When two-way mobile radio was being introduced to taxicabs, railroads, power companies, pipe lines and industry in 1948, Hammarlund became the first to bring out selective calling equipment. By means of push buttons, individual cars could be alerted without disturbing others in the same fleet. Regards, Greg Gore In a message dated 10/27/2009 1:46:52 P.M.

The power transformer was definitely out of commission so I decided on a replacement and if everything works allright then I will go for a rewinding of the old one. In any case the replacement can be used in many other receivers. The replacement transformer was easily installed and new power supply electrolytics were put in place too. All tube sockets were cleaned and given a Deoxit bath. Tubes were replaced. One paper cap was replaced and one RF filter coil repaired. Checking and rechecking revealed no other major issues so I decided on a smoke test in Band 1. It came out alive and well and so did bands 2 to 4. On band 5 there was no signal but I discovered that L19 was out of adjustment. Bands 5 to 6 were well but needed alignment. The GPR was alive and working. More cleaning of the tuning cap section followed with lubrication of gears and the chassis was scrubbed too without removing the tube labels. Yesterday a preliminary alignment was done and everything improved a lot. A finer alignment will follow. I am now polishing the tube shields. Some issues that I have observed: Meter pegs to the left under no signal conditions and no adjustment affects this. BFO injection circuit has a 56pF cap instead of the 15pF one. It also has an additional 18megohm resistor from pin 6 of the BFO tube to ground. More will follow.

It had been cut and left hanging on one lead while the 56pF cap was badly soldered in its place. The signal is definitely lower now but more manageable. The tendency of the meter to peg to the left with no signal is gone after further cleaning of associated tube socket contacts. Now I can adjust the meter correctly. Further alignment will be done tomorrow. Audio is great with that solitary 6V6. 73s Guido Santacana KP4FAR San Juan, PR, USA ----- Original Message ----- From: "Singley, Rodger" To: Sent: Tuesday, October 27, 2009 7:03 PM Subject: RE: TMC-GPR90 Report Guido, Sounds good so far. The change in BFO caps was to increase the rather weak injection but it does tend to increase the tendency for BFO pulling on strong signals. You will probably want to use an external adapter for CW/SSB usage. The GSB-1 would be great but they are incredibly high priced. I use a Hammmarlund HC-10 but the CE "sideband slicers" will also work well.
