Someone was seeking a Drake SL1800 Filter for the R7 or TR7, I have one. They are going for $80 to $90 on the bargain site. Mine is $70 shipped in CONUSA. Gary W0DVN

Drake MN 2700 Matching Network In very good condition. Maybe a little Windex may help. I am the second owner, No need for me to describe this "tuner". Drake guys are familiar.:-) $300 plus shipping.

Not that I recall. I would loosen the lower cover screws so you can get the top cover to come away easily. Gary W0DVN

Do you really have to remove the bottom cover before the top part of the case can be removed (so you can get to and replace the meter lamps)? W3RJ

Joe's answer is correct, but it is worth pointing out that the accuracy of any digital frequency counter display is going to be +/- 1 count. So technically your are still close to spec. With careful

Thanks Joe I thought that might be it but I wasn't sure.Sent from Samsung Galaxy smartphone.

If the rest of the radio is in alignment, adjust L1001 on the PBT/Reference board which adjusts the 40 mhz oscillator which is divided down to 500 khz for the display time base. 73, Joe Pyles KC9LAD

Can someone tell me what to adjust on a TR-7 when the freq is slightly off? My radio tunes 14.279.9 for instance on SSB instead of 14.280. Dan K9DTC

Yep, I'm working on a T-4XB right now that has no output of the CO and control of that goes through at least two switch wafers. V1.2 and V1.3 are giving me fits. they should be 1.6 and 4.2V,

*** Me neither. Nothing will stop me from fixing a piece of equipment faster than a problem hidden in a mass of rotary switches. That being said - is there a standard for labeling switch wafers? I

Yeah, RTTY mode is an anachronism from before the days of computer generated tones. The ACG time constants and of course the fixed passband are altered from the normal SSB values. It has occurred to

Bill - If you end up needing to buy a crystal for your TR-4, please consider my company, AF4K Crystals. Here's a direct link to my web-store page where I offer the crystals suitable for the TR-4...

True, that. I'm thinking more along the lines of checking out those settings. I just did the check with my TR7A and they all line up except for RTTY, which I have not done because I'll likely never

Well, it is not perfect but it gets you "close enough" in a pinch. However, since you need a counter for the rest of the frequency alignments I see no reason to go halfway. If you are the sort to

Hi Jim Thanks for the message I just checked the adjustment on CW, it seemed to be ok, zero beat at 13694.2Mhz But whereas the USB and LSB only gives one tone as its tuned across, in CW going from low

I’d never seen this particular procedure before. Interesting and I assume that it eliminates the need for a counter. Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a banana. Sent

Check the fixed passband adjustments. You may want to start with 3-1 10 Volt adjustment and proceed through 3-6 Fixed Passband adjustments. There is also a quick and dirty adjustment procedure from

Hi Fairly new to TR7 ownership here, and apologies in advance if this is a silly question. In CW mode when tuning through a signal (or the calibrator tone), the main signal appears ok, then moving
