QC I had seven DX3 models through my hands lately, every one had to be fully realigned, and the SO-239 was loose on all rigs. Today Quantity takes priority over Quality, this is true of most manufacturers not only Ranger, and this is why most major outlets offer a peak and tune service...

Yaesu FT-857D & MH-59 I managed to resolve the feedback problem with the MH-59. In the car Yaesu suggest connecting the negative power lead to the battery terminal, I cut the negative lead and fuse holder off, soldered a lug on and connected to the chassis. I then grounded the rig via the...

Yaesu FT-867D & MH-59 Some folk blame bias settings for the problem, however, mine checked out ok! The MH-59 is the culprit, fitting two clip on ferrites at either end had no effect, but gripping the mic lead tightly by hand my body capacitance fixed the problem, no more RF feedback. Even...

Vortex Quasar .64 I took delivery of the Vortex Quasar 64 recently. Out of the box you are immediately struck by the great build quality. I tend to take a lot of time building antennas and the Vortex was no exception. All the joints were waterproofed using C-Seal, a compound I've been using for...

The TS-590S is a total pain if you plan to use an LA due to the ALC overshoot powerspike which causes my Acom protection circuit to kick in. This is simply poor design, the ALC circuit is still pulling its boots on and the powerspike has come and gone in about 5mS. It cannot be fixed by firmware...

Make sure the AT-50 is connected to the TS-50 then power the rig on. The AT-50 should at least attempt to tune the mismatch on demand. Try pressing and holding AT Tune key for two seconds as this will enable Thru mode then you can establish if the AT is contributing to the problem or the rig...

Move the jumper across from Local to DX. That is from CN103 to CN102.

RCI-2950DX3 I bought four 2950's recently, and every single one needed attention. The SO-239 retaining nut was barely more than finger tight, and the TRX alignment needed attention too as did the TX output which measured between 5 and 8 watts PEP and 3 and 6w on AM/FM on 10m. It seems to me...

Image Rejection Mod Ranger won't do the FL3 mod because they deny there is a problem! Anyway, I fitted the BHI NEDSP1061-KBD DSP unit and it does a good job of cleaning up the white noise and a host of other undesirable noises!

Firmware Update 1.6 (EXP) Got an email from Sam Yaesu UK below...... You should not have uploaded the update to Yahoo Group. Software should only be available from our official website. I know you believed what you were doing was correct but please do not do something like this again. We...

Hi Doc & Vanilla Sky, the jury's still out on that one, however I'm inclined to lean towards the effects of the thunderstorm as lightening struck the QTH and all the trips when off causing a power outage. The 350 was not connected to an external antenna but a WonderWand multi bander, it was...

Faulty Firmware 1.6 My 350RE has firmware 1.6 apart from a few minor bugs it worked great. However, after a violent thunderstorm everything went pear shaped and it began behaving badly, mere coincidence or what I don't know. Now my FTM-350RE has been consigned to storage as I can't get a 1.6...

Hi James, manual: http://www.cbtricks.com/ant_manuals/avanti/av174/graphics/sigma4_av174_om.pdf Had one many years ago, the only problem I had was the gamma match, changed that for an air variable capacitor fitted in a water proof box with a protruding tuning wheel, worked very well with none...

The TS-440 is not designed for Hi-Fi audio, so don't waste your money on expensive mics. The standard dynamic hand mic through the MC desktop series (except MC-90) and similar mics already mentioned elsewhere do a good enough job for communications. The TS-440 is very prone to picking up RF in...

TS-440 AM TX Drop the carrier power to around 20 / 25 watts, reduce the mic gain to eleven o'clock, speak in a normal voice and observe the slightest ALC meter deflection. Works for me!
