Mike: One of the boards, the one with the display, lifts out, but you have to remove the front panel and pull it forward to gain enough clearance to remove the boards. To get the front panel off, rem
Oh, by the way, to clean out the meter, cut a sliver of double-sticky-sided Scotch tape, hold it with a tweezer, and carefully insert it into the meter armature. The sticky tape will pick up any fore
I would like to improve the SSB/CW selectivity of my 1254 receiver. 455 kHz filters narrower than 4 kHz are very expensive. I thought of trying to make a filter out of 455 kHz ceramic resonators, but
Yes, the 1254 provides a great foundation for modification or experimentation. I put an RCA jack on the rear panel for muting the receiver, but I have not yet tried it with a transmitter. I might mod
Lee: Yes, that is another option. The AGC is not audio derived, but an audio filter would work fine. There are lots of active filter designs around. I was thinking about the Idiom Press SCAF filter.
That's exactly what I was doing today: looking at the QF-1 schematic to see if it could be done with FET's. That Q-multiplier from the 1958 Handbook sounds like the same one that I built from the 196
I searched for Q-Multiplier, but it mainly led me to the boat anchor Q-Multipliers. Then I searched for SM0VPO and I found the schematic. I'll give it a try, its certainly simple. Thanks. 73, Bob WB2
No, as I understand it, its a California thing. Look at any product that uses solder and you will see a notice that the state of California has determined that the product contains known carcinogens.
I use FSK with my Paragon and a Kantronics KAM. It works fine. To go to the RTTY mode, press SHIFT then CW. This should give the proper offsets. I run with the PBT centered with all filters except th

Ed: Try different values for the temperature compensating capacitor. This is selected at the factory, but you may get better results from another value. Only trouble is, N750 caps are hard to find, b
Ed: That's excellent, very low drift. Hardened PTO grease usually causes frequency jumping, not warm-up drift. I had it really bad with my Corsair, until I rebuilt the PTO. The components were not re

Luca: Just turn down the monitor control on the back panel. This is a voice sidetone for checking the speech processor, but it isn't particularly useful. 73, Bob WB2VUF Hi to All I am new member of t
You're right, Clark, noise blankers represent tradeoffs. For example: My Corsair: no distortion, but limited noise blanking ability. Paragon: great blanking, but introduces distortion, typically key
I'm thinking the same thing. I have a Drake tuner with an antenna switch to select between 2 antennas, and a separate switch to select among the Ten-Tec and Heath rigs, but it would be nice to put 2

Yes, I remember that antenna. It was a broadband dipole that had transformers and resistors built into the center insulator. QST actually x-rayed and disassembled the potted assembly. Some of the cir
Its a mystery to me why hams would go for a broadband antenna of any kind, when a dipole fed with ladder line and used with a decent tuner (auto or manual) is cheaper and more efficient. Yet, I const
