By the way, 210 00:10:37,639 --> 00:10:41,079 I'm curious 211 00:10:39,720 --> 00:10:43,440 See what he's like inside, right? 212 00:10:41,079 --> 00:10:47,959 Let's see everything. In fact, the equipment 213 00:10:43,440 --> 00:10:47,959 It's new, new, new, new. 214 00:10:48,040 --> 00:10:51,040 Nothing 215 00:10:51,839 --> 00:10:55,000 to add 216 00:10:56,560 --> 00:10:59,560 negative. 217 00:11:01,120 --> 00:11:07,880 Everything seems original to me, 218 00:11:04,160 --> 00:11:11,800 no finger marks, no marks like that 219 00:11:07,880 --> 00:11:11,800 things, everything 220 00:11:13,639 --> 00:11:22,560 everything beautiful. On this side, the same thing. 221 00:11:18,279 --> 00:11:22,560 Everything is impeccable. 222 00:11:25,639 --> 00:11:29,959 The equipment is actually new, 223 00:11:32,720 --> 00:11:37,120 It's not even a year old. 224 00:11:35,399 --> 00:11:40,120 So there is not here, in fact, it will be 225 00:11:37,120 --> 00:11:40,120 new. 226 00:11:40,279 --> 00:11:46,279 There is nothing here that says the 227 00:11:42,959 --> 00:11:46,279 equipment has been disturbed. 228 00:12:21,120 --> 00:12:24,120 Yeah, 229 00:12:24,519 --> 00:12:29,480 I don't have a big one 230 00:12:27,399 --> 00:12:32,240 great thing to say. I put the 231 00:12:29,480 --> 00:12:36,040 covers on the equipment, but to make 232 00:12:32,240 --> 00:12:39,360 tests. Why? Because even before 233 00:12:36,040 --> 00:12:41,040 go and touch the PA, we have to see if there is 234 00:12:39,360 --> 00:12:42,680 even need it. And I think 235 00:12:41,040 --> 00:12:45,839 there is not. I think the equipment is 236 00:12:42,680 --> 00:12:48,959 very good. I didn't put the screws in, 237 00:12:45,839 --> 00:12:53,000 but the equipment is very good 238 00:12:48,959 --> 00:12:56,000 part regarding the bias adjustments of the 239 00:12:53,000 --> 00:12:57,120 of HF and DHF and therefore I do not see 240 00:12:56,000 --> 00:12:59,639 absolutely no need for 241 00:12:57,120 --> 00:13:02,360 be there moving. And for you 242 00:12:59,639 --> 00:13:06,639 try it, I'll show you, I'll do it, let's go 243 00:13:02,360 --> 00:13:09,079 do an IMD test here, i.e. and 244 00:13:06,639 --> 00:13:11,920 distetor by intermodeling. And let's go 245 00:13:09,079 --> 00:13:14,000 Also do the envelope test. 246 00:13:11,920 --> 00:13:16,440 SSB. You will see that the PA is 247 00:13:14,000 --> 00:13:18,000 work perfectly, without any 248 00:13:16,440 --> 00:13:21,199 problem. 249 00:13:18,000 --> 00:13:23,959 In this case, let's do the test first 250 00:13:21,199 --> 00:13:26,199 of IMD. 251 00:13:23,959 --> 00:13:30,320 The intermodeling destruction test. 252 00:13:26,199 --> 00:13:32,560 We're going to inject a double tome, 253 00:13:30,320 --> 00:13:36,000 so let's broadcast it and let's see on 254 00:13:32,560 --> 00:13:39,880 in the spectrum analyzer how do 255 00:13:36,000 --> 00:13:43,639 is there 256 00:13:39,880 --> 00:13:48,000 third order intermodeling. 257 00:13:43,639 --> 00:13:51,199 For that we have to have one here, yeah 258 00:13:48,000 --> 00:13:53,600 It is important that the ALC does not act. This 259 00:13:51,199 --> 00:13:56,240 why? Because the ALC will block, 260 00:13:53,600 --> 00:13:58,920 let's say, the purity of the PA and the 261 00:13:56,240 --> 00:14:01,600 the AC must be turned off. You have to be 262 00:13:58,920 --> 00:14:04,279 to zero. And to do this we have to reduce the 263 00:14:01,600 --> 00:14:08,839 mic gain. In this case I reduced it to 18, 264 00:14:04,279 --> 00:14:12,360 are you seeing? And without so that the 265 00:14:08,839 --> 00:14:14,720 OLC. The power is 30. Maybe, maybe 266 00:14:12,360 --> 00:14:16,680 be. There is no need to be the 100 W, 267 00:14:14,720 --> 00:14:19,959 it can be between 20 to 50 W. I have it here 268 00:14:16,680 --> 00:14:19,959 30W. 269 00:14:20,600 --> 00:14:26,320 So, Micanin at 18. 270 00:14:24,000 --> 00:14:28,160 We are here generating 271 00:14:26,320 --> 00:14:31,560 a doublet, 272 00:14:28,160 --> 00:14:36,839 one at 700 Hz and another at 1900. It is a 273 00:14:31,560 --> 00:14:39,839 standard thing. Then the two tones come out and 274 00:14:36,839 --> 00:14:42,079 go here to this to this mixer done 275 00:14:39,839 --> 00:14:46,639 for me. 276 00:14:42,079 --> 00:14:48,880 H, and go to the microphone. The little cable 277 00:14:46,639 --> 00:14:51,160 also made by me from the microphone with 278 00:14:48,880 --> 00:14:54,279 a little PTT 279 00:14:51,160 --> 00:14:57,519 for radios and ESO. After that, 280 00:14:54,279 --> 00:15:00,560 comes out from behind the transmission of the 281 00:14:57,519 --> 00:15:04,440 equipment in SSB, 282 00:15:00,560 --> 00:15:06,800 go this way, go up and go to the 283 00:15:04,440 --> 00:15:13,399 spectrum analyzer. 284 00:15:06,800 --> 00:15:15,040 OK. We have 10 kHz spam here 285 00:15:13,399 --> 00:15:16,639 and let's see what will happen. 286 00:15:15,040 --> 00:15:19,759 Let's see what we're going to get 287 00:15:16,639 --> 00:15:22,639 there when we broadcast. OK? So I will 288 00:15:19,759 --> 00:15:24,519 transmit. 289 00:15:22,639 --> 00:15:27,880 If you guys stop, I'm streaming. Se 290 00:15:24,519 --> 00:15:30,839 you notice the LC is not 291 00:15:27,880 --> 00:15:32,480 works, or rather it's not showing up, 292 00:15:30,839 --> 00:15:35,079 which is good. Let's pass the gain here 293 00:15:32,480 --> 00:15:37,000 from the microphone to 19. 294 00:15:35,079 --> 00:15:40,000 appeared soon. Do you see this the ALC 295 00:15:37,000 --> 00:15:43,800 This equipment is very aggressive. 296 00:15:40,000 --> 00:15:45,839 So you're at 19, let's get it down to 18. 297 00:15:43,800 --> 00:15:48,680 And so we are left with the ALC is zero. They are 298 00:15:45,839 --> 00:15:51,800 to see? It dropped to zero. The power 299 00:15:48,680 --> 00:15:54,399 resulting here from this transmission 300 00:15:51,800 --> 00:15:59,959 of this two-tone SSB broadcast 301 00:15:54,399 --> 00:16:03,800 it's 20 W in SSB, isn't it? 302 00:15:59,959 --> 00:16:06,560 And let's see how it goes 303 00:16:03,800 --> 00:16:09,440 spectrum analyzer. 304 00:16:06,560 --> 00:16:12,440 We have all these peaks. And, by the way, 305 00:16:09,440 --> 00:16:17,279 let's do this here, one swip 306 00:16:12,440 --> 00:16:20,560 It's unique, single. 307 00:16:17,279 --> 00:16:22,800 OK. Ready. So we can stop 308 00:16:20,560 --> 00:16:25,160 transmit, 309 00:16:22,800 --> 00:16:28,000 it's better. And now we have, let me go 310 00:16:25,160 --> 00:16:30,759 get up. And now we have here 311 00:16:28,000 --> 00:16:36,880 spectrum analyzer. We have here the 312 00:16:30,759 --> 00:16:39,839 700 Hz peak and 1900 Hz peak. 313 00:16:36,880 --> 00:16:42,000 What interests us here is this peak here 314 00:16:39,839 --> 00:16:43,399 third order 315 00:16:42,000 --> 00:16:46,720 who is here, who is the biggest, are 316 00:16:43,399 --> 00:16:50,000 see? After the two tones, it is 317 00:16:46,720 --> 00:16:53,920 third order. It’s important to see which one it is 318 00:16:50,000 --> 00:16:56,120 the difference between this and this, being that 319 00:16:53,920 --> 00:16:58,399 eh 320 00:16:56,120 --> 00:17:04,199 if it is 321 00:16:58,399 --> 00:17:07,199 is greater than - 30 dBs, - 30 dBs 322 00:17:04,199 --> 00:17:09,640 it will be good. If it's smaller that's also good, 323 00:17:07,199 --> 00:17:13,240 but every time it's that distance 324 00:17:09,640 --> 00:17:16,799 is shorter and worse. If this peak 325 00:17:13,240 --> 00:17:19,480 third order is higher is bad. 326 00:17:16,799 --> 00:17:21,760 This means that the equipment is not 327 00:17:19,480 --> 00:17:25,880 with intermodel destruction 328 00:17:21,760 --> 00:17:29,840 Too much, right? And so, let's go. 329 00:17:25,880 --> 00:17:33,480 Eh, let's put it here, wait, 330 00:17:29,840 --> 00:17:35,160 let's put the delta here. 331 00:17:33,480 --> 00:17:38,840 OK. I've already adjusted it here more or less 332 00:17:35,160 --> 00:17:40,080 so you can see. 333 00:17:38,840 --> 00:17:43,919 And what is this, what is the difference that 334 00:17:40,080 --> 00:17:49,760 we have here from the 700 Hz peak to here 335 00:17:43,919 --> 00:17:54,960 for third order is -31.5 336 00:17:49,760 --> 00:17:58,280 dB? In other words, it's good, it's very good, 337 00:17:54,960 --> 00:18:00,720 because if it were below 30 it would be bad, 338 00:17:58,280 --> 00:18:04,760 but 339 00:18:00,720 --> 00:18:06,679 31, almost 32, it's very good. It is 340 00:18:04,760 --> 00:18:11,640 fantastic. There's no need to be 341 00:18:06,679 --> 00:18:13,960 messing with the PA equipment. 342 00:18:11,640 --> 00:18:15,320 We can see some destruction here 343 00:18:13,960 --> 00:18:18,159 in the passband. This is the band 344 00:18:15,320 --> 00:18:20,280 through the equipment. Is there anything here 345 00:18:18,159 --> 00:18:21,919 destruction, some noise. This here, 346 00:18:20,280 --> 00:18:24,720 It's probably phase noise from the 347 00:18:21,919 --> 00:18:28,000 oscillator or DSP. 348 00:18:24,720 --> 00:18:30,919 It's not critical. Now here this peak of 349 00:18:28,000 --> 00:18:34,480 third order, yes, here is if it were 350 00:18:30,919 --> 00:18:38,600 higher was worse. In other words, 351 00:18:34,480 --> 00:18:40,760 higher more destruction. OK? Therefore, 352 00:18:38,600 --> 00:18:44,159 the equipment is fantastic in terms of 353 00:18:40,760 --> 00:18:47,360 touch IMD. Now let's do the test, 354 00:18:44,159 --> 00:18:48,919 but in this case from the SS envelope. 355 00:18:47,360 --> 00:18:51,840 >> The configuration is basically the same, 356 00:18:48,919 --> 00:18:56,200 while 357 00:18:51,840 --> 00:18:58,159 in the IMD test we do it here, very 358 00:18:56,200 --> 00:19:00,320 although it can also be done in 359 00:18:58,159 --> 00:19:02,679 oscilloscope, but in the case of the 360 00:19:00,320 --> 00:19:07,320 IMD, we did it here in the 361 00:19:02,679 --> 00:19:09,840 the test spectrum and the SSB envelope. 362 00:19:07,320 --> 00:19:12,640 do it here. See? It's already there 363 00:19:09,840 --> 00:19:15,640 transmit. I'll even do it here. I will 364 00:19:12,640 --> 00:19:15,640 stop. 365 00:19:16,120 --> 00:19:23,080 It stopped. And as you see, 366 00:19:19,960 --> 00:19:24,679 it's perfect. It's fantastic. It's not 367 00:19:23,080 --> 00:19:28,400 flat 368 00:19:24,679 --> 00:19:32,520 us on the peaks. 369 00:19:28,400 --> 00:19:34,679 The intersection point is clearly marked there. 370 00:19:32,520 --> 00:19:38,120 It's fantastic. 371 00:19:34,679 --> 00:19:44,600 SSB envelope looks fantastic. 372 00:19:38,120 --> 00:19:47,760 Now there is a question. They want to see if I 373 00:19:44,600 --> 00:19:49,919 Here the ALC is not acting, is it? But 374 00:19:47,760 --> 00:19:52,280 If I get the ALC to act, let me put 375 00:19:49,919 --> 00:19:54,880 here again o o 376 00:19:52,280 --> 00:19:56,880 oscilloscope a 377 00:19:54,880 --> 00:20:00,480 without being 378 00:19:56,880 --> 00:20:03,159 fixed. Let's broadcast and let's go. They are 379 00:20:00,480 --> 00:20:06,360 see the LC went up a little, but let's 380 00:20:03,159 --> 00:20:09,799 make it go up a little more. 381 00:20:06,360 --> 00:20:13,520 For example, let's put it here. 382 00:20:09,799 --> 00:20:16,200 You will see the ALC already there. They want to see 383 00:20:13,520 --> 00:20:18,799 Now here's the envelope? 384 00:20:16,200 --> 00:20:22,000 Maybe it's already starting to flatten here. I 385 00:20:18,799 --> 00:20:25,400 I will increase more. I will increase until 386 00:20:22,000 --> 00:20:29,039 to the maximum limit 387 00:20:25,400 --> 00:20:33,200 of the ALC, 388 00:20:29,039 --> 00:20:36,880 which is in that area. Are you seeing it? 389 00:20:33,200 --> 00:20:41,159 I'm holding the microphone here at 49 390 00:20:36,880 --> 00:20:44,080 and the ALC at the maximum limit. 391 00:20:41,159 --> 00:20:48,679 You see here the 392 00:20:44,080 --> 00:20:50,600 Are the peaks already flat? So the 393 00:20:48,679 --> 00:20:52,000 see? 394 00:20:50,600 --> 00:20:56,640 Let it go broadcasting. In fact, 395 00:20:52,000 --> 00:20:58,240 let's put it here. Let's stop. Let's go 396 00:20:56,640 --> 00:21:01,960 let it be transmitted so as not to be here 397 00:20:58,240 --> 00:21:04,960 force the radio. See? is already 398 00:21:01,960 --> 00:21:04,960 flatten. 399 00:21:05,200 --> 00:21:13,919 In other words, the fact that we have increased the 400 00:21:10,279 --> 00:21:16,679 ALC up to the limit on this equipment does not 401 00:21:13,919 --> 00:21:18,240 It's a very good idea. it is convenient that the 402 00:21:16,679 --> 00:21:21,760 ALC is always a little more 403 00:21:18,240 --> 00:21:25,320 below, but this also demonstrates that the 404 00:21:21,760 --> 00:21:28,840 SSB envelope and in this case the PA 405 00:21:25,320 --> 00:21:32,360 it's working perfectly. 406 00:21:28,840 --> 00:21:34,159 The service menu has been readjusted 407 00:21:32,360 --> 00:21:37,600 for powers slightly above 408 00:21:34,159 --> 00:21:41,000 100, that psychological barrier 409 00:21:37,600 --> 00:21:44,440 to be outdated. So let's go 410 00:21:41,000 --> 00:21:47,880 test. I did a reset again after 411 00:21:44,440 --> 00:21:50,480 adjust the service menu and let's test 412 00:21:47,880 --> 00:21:54,200 all bands. See how they turned out. 413 00:21:50,480 --> 00:21:54,200 160 m. 414 00:21:54,360 --> 00:22:00,279 OK. ALC 415 00:21:56,279 --> 00:22:03,279 It's OK.

Eh, 422 00:22:19,039 --> 00:22:26,679 let's go to LSB, let's put it on CW. 423 00:22:23,880 --> 00:22:28,480 We have to go up a little. 424 00:22:26,679 --> 00:22:31,679 We broadcast 425 00:22:28,480 --> 00:22:36,080 LC.

I don't think so. If they 489 00:26:16,440 --> 00:26:21,399 are for 100 W, it is supposed to be 100 W or a 490 00:26:18,240 --> 00:26:23,640 a little more. Leave it even at 100 W 491 00:26:21,399 --> 00:26:26,640 sure, I don't think it's good 492 00:26:23,640 --> 00:26:26,640 politics. 493 00:26:27,399 --> 00:26:32,039 I know that most of the OMs 494 00:26:30,480 --> 00:26:34,640 like 495 00:26:32,039 --> 00:26:37,080 let it be a little more. 496 00:26:34,640 --> 00:26:38,919 I know that right there at 100 is that 497 00:26:37,080 --> 00:26:41,279 it was that fantastic thing, but we know 498 00:26:38,919 --> 00:26:43,120 than with heating, with 499 00:26:41,279 --> 00:26:46,360 operation always drops a little. 500 00:26:43,120 --> 00:26:48,039 So if we leave it a little longer it will stay 501 00:26:46,360 --> 00:26:52,039 very well.
