View all posts by Alexandru Csete. You need a fine-tipped soldering iron, a steady hand, and good soldering technique to be successful.

I checked the output diodes to see if it had been over driven but they seemed fine. The IF command contains the frequency that the radio is tuned to. I have the same setup, and I just send a string of dits. Fed from a banana plug to bnc adapter directly on the T1.

Maybe the antenna is bad, I thought.

I know a transmatch will always Introduce some loss based on match differences, but they did a good job with this tuner. The T1 has 7 inductors and 7 capacitors to provide a wide tuning range. The explanations are simple and clear and illustrated when appropriate, though I did notice a couple of minor errors.

There are a number of header sockets on the board which are elecrafft simply to support the Arduino. Fortunately, I did not elecrft to do that.

It was an easy kit to elecaft all components that need to be installed are through-hole, you just need to make sure the leads are clipped off FLUSH with the board surface after soldering. The most interesting question is, of course, what can the T1 tune and how fast? It’s worked well since day 1.

I tried a new antenna. For power and SWR measurements the T1 uses a directional coupler. Eecraft amateur and SDR hacker during the night. The assembly manual is very detailed. The details are described in the T1 manual on page 8. One should keep in mind that the T1 is intended to be a portable or mobile equipment.

Inside the mini-DIN plug, is a tiny circuit board made with SMD components, including a tiny microprocessor control unit. There are several options, depending on whether you tap or hold the buttons, but don’t worry if you have a memory like a sieve like me: One must keep in mind that this is a pocket size tuner and the space is really tight, so it is a little difficult elecfaft solder at many places.

A jewel of electronic device. The T1 is very fast, since the best match is usually found within seconds.

Embedded software engineer in the satcom industry during the day. Re-tunes, such as when you change frequency within a band using a sharply resonant antenna, take a fraction of a second.

Before matching starts, the T1 determines the peak power of the transmitted signal, then uses a large fraction of this value as a qualifier for SWR readings. The second button is used in combination with the first to switch the tuner in-line or to bypass it, or if you press, hold, and eleccraft, it will give you detailed power g1 SWR information flecraft blinking the yellow LED in slow Morse.

Anyway, there should be no doubt that if you just follow the very good assembly guide step by step it will work out just fine. This type of bridge is inherently balanced over a wide frequency range and requires no adjustment. Open Design, No Secrets: It’s powered by the FT itself, drawing a tiny current. The same goes for power reading. This was matched with a 1: To initiate a tune, the power button is held until the green LED comes on; you must then transmit within three seconds.

It has a good tuning range and tunes very reliable. New to Ham Radio? Since I can’t see the point of using a great big computer to control a little tiny radio, I don’t regard it as much of a problem. In this way, SSB voice as well as any other modulation method can be used elecrfat tuning, with little loss of accuracy compared to the use of a constant carrier.

The 3B weighed around g versus the g of the 2B which came before. It matched elecgaft small non-resonant attic loop, which has an SWR of more than Using the T1’s Info mode another button tap combination you can find out even more information, such as the internal battery voltage, inductance and capacitance selected, network configuration and band in use.

It can be used with any 0. The EF Random wire was around 80 to feet I think An internal 9-V battery powers the unit, and battery life is excellent thanks to the use of latching relays and auto power-off after each use.

Elecraft is known for their excellent construction manuals, and this, of course, is no exception. Had the top off my old MTR-5B tonight as I thought it might benefit from a back up battery change before my winter bonus activation period really kicks off. The 3B was first offered as a self build kit, again with a case by TenTec, but this time all aluminium.

Using band data via remote control can, however, reduce this time by eliminating some L and C values based on the operating band. I also tried a 5m length of wire draped over a curtain rail, using the central heating system for a ground.
