Hi! After I returned from Dayton last week, I ordered a Wouxun KG-UV8D 2m/70cm FM HT. Even after working Andy W5ACM while I was at Dayton, and reading his e-mail where he mentioned he used a KG-UV8D for that QSO, I still wanted to see for myself. I ordered the radio last Tuesday (20 May) from MTC, and it was delivered at my office by USPS Priority Mail two days later. Along with the radio, I ordered a programming cable. The programming cable was not necessary, as this radio is compatible with the programming cable used for Baofeng (and other Wouxun) radios, but I have it anyway. Out of the box, the radio was open from 135 to 174.995 MHz and 400 to 479.995 MHz. There is software from the Miklor UV8D pages that is supposed to open the radio up to 134-174 MHz and 400-519 MHz. I have not used this software, since I don't have a need to transmit above 480 MHz. This HT is not compatible with the open-source CHIRP radio-programming software at this time, so I had to use the Wouxun software to load the memory channels (I received a small CD with it, or the Miklor site also has it). This radio carries the same FCC ID number as Wouxun's KG-UV6D. On the back of the radio, below the FCC ID/warning label, the aluminum case was engraved with "MTC - USA version". It is interesting that this radio carries the same FCC ID number as the Wouxun KG-UV6D, although this radio appears to have more functionality than the UV6D - except in one regard. The UV8D does not tune in 2.5 kHz steps. For some reason, this was left out of the radio, but is present in the previous UV6D. I can enter frequencies that would normally be reached with 2.5 kHz steps in the VFOs, but those frequencies are rounded down when stored in memory channels (i.e., 436.8025 becomes 436.800). The UV8D has the capability to receive from both VFOs, regardless of the frequency in each VFO, and one VFO can be turned off, if you don't want to hear from both VFOs. Before continuing, I will answer the question that most FM satellite operators have about this radio. I won't make you wait to get the answer, since it really doesn't take many months to figure this out. Does the KG-UV8D do cross-band full-duplex operation for SO-50 (transmitting on 2m while simultaneously receiving the satellite downlink on 70cm)? No. As I transmitted on 145.850 MHz to SO-50, the other VFO with the 70cm downlink frequency was desensed. The behavior is similar to what I heard with the Alinco DJ-G7T 2m/70cm/23cm FM HT a few years ago, and what was (finally, after 6 months) reported for the Puxing PX-UV973 2m/70cm FM HT. Andy W5ACM told me about what he saw when he used his KG-UV8D on SO-50, and my findings mirror what he told me. This radio might work better if the uplink and downlink bands are reversed, as will be the case with AMSAT's Fox-1 satellite due to be launched next year, but it doesn't do full-duplex for SO-50. I used my Elk Antennas 2m/70cm log periodic antenna and (briefly) my Arrow Antenna 146/437-10WBP 2m/70cm Yagi for these tests, although all QSOs were completed with the Elk log periodic. The KG-UV8D's receiver is certainly better than the Alinco DJ-G7T, more sensitive and selective than that radio. Compared to the Baofeng UV-5R and UV-82 HTs I have been using for the past few weeks, I can say that the UV8D's receiver is at least as sensitive as the Baofeng HTs, and more selective. My Icom IC-2820H 2m/70cm FM mobile transceiver still has a more sensitivie and more selective receiver than any of these Chinese-made HTs, including the UV8D. The UV8D's transmitter is supposed to put out 5W on VHF and 4W on UHF, and tests have confirmed that the radio puts out at least that much. One peculiar "feature" - for lack of a better word - I see with the KG-UV8D is that when I would normally adjust my 70cm receive frequency to copy SO-50, there are moments when I wish this radio had the 2.5 kHz tuning steps. When I am having difficulties clearly hearing the voices on a frequency like 436.800 MHz, I'm not clearly hearing them on 436.795 MHz either. This doesn't appear to be an issue with most non-Chinese HTs or FM mobile transceivers I have used over the years. I just have to wait a moment for the satellite to move, and the downlink frequency get closer to the next (lower) tuning step to clearly hear the voices again. This repeats each time I need to tune down to the next tuning step during an SO-50 pass. After working SO-50 with the KG-UV8D and Elk log periodic antenna on 24 May, I went to a two-radio setup similar to what I have been doing with my Baofeng HTs. Taking advantage of the better receiver in the UV8D compared to the Baofengs, I used the UV8D as the 70cm downlink receiver. I used a Baofeng UV-82 with a dual-PTT speaker/mic as my transmit radio, since I could put 145.850 MHz in each of the UV-82's VFOs, with a different PL tone for each VFO (74.4 Hz for the upper VFO using the upper PTT on the speaker/mic, and 67.0 Hz for the lower VFO using the PTT on the left side of the speaker/mic). Plugged into the KG-UV8D's speaker jack is my splitter cable, to feed the receiver audio to an earpiece and my Sony audio recorder. The dual-PTT speaker-mic is plugged into the UV-82. The UV8D, like the Baofeng and many other Chinese-made HTs, are compatible with Kenwood speaker/mics if you already have one of those. Both radios are connected to a 2m/70cm diplexer, since the Elk has only one coax feedpoint. Other than the pecularities when it was about time to change my receive frequency, I saw no desense on the KG-UV8D's receiver when I transmitted with the UV-82. This leads me to believe the issues with the KG-UV8D and cross-band full-duplex operation are internal to the radio. When working with stronger signals - local repeaters, or when I transmit with one of my many Baofeng or other radios - the KG-UV8D had no problems serving as a cross-band repeater, no matter which direction it was retransmitting (receive 2m and transmit on 70cm, or receive on 70cm and transmit on 2m). As with other radios, or combinations of radios, that are capable of serving as a cross-band repeater, please comply with your local regulations on the operation of cross-band repeaters (in the USA, these are usually classified as "auxiliary stations" in the FCC Part 97 rules). The KG-UV8D has a female SMA antenna connector on the top of the radio, the same type of SMA connector used by Icom/Kenwood/Yaesu/Alinco HTs (and different from the male SMA connector on my Baofeng UV-5Rs and UV-82s). I put a Diamond BNCJ-SMAP adapter on this SMA connector, and now use antennas and coax with BNC connectors with this radio - my normal setup for all of my radios I use with satellites. I have an assortment of antennas and coax with BNC connectors, so I won't need to remove the adapter from the UV8D. Another practical observation... the LCD display. In bright sunlight, the KG-UV8D's display is difficult to see - similar to the LCD displays used on many mobile phones, tablets, and laptops. Without the backlighting activated, I could not read the LCD display at all, so I leave the backlighting on all the time. This doesn't appear to be a huge drain on battery life. Most other radios I have, or have used in the past, don't use LCD displays that are this difficult to read in bright sunlight. The supplied 7.4V/1700mAh lithium-ion battery pack is a good choice for this radio. Wouxun has a larger 7.4V/2600mAh pack, the BLO-009, but at present it doesn't appear to be available from stateside distributors. If I use eBay or other offshore radio shops, I can order them from the Far East. I have not seen any AA or AAA battery cases for this radio yet, but those may be coming later. This is still a relatively new radio. There you go. Is the KG-UV8D worth the purchase price? That is up to you. It is a neat radio, a little larger and heavier than other Wouxun and Baofeng radios I have used over the years. I'll keep the UV8D around, and use it as part of my SO-50 satellite demonstrations, along with another HT (probably a Baofeng UV-5R or UV-82) to demonstrate full-duplex FM satellite operation. It's one thing to talk about full-duplex operation, but another to actually demonstrate it for a crowd - something I did with a UV-82/UV-5R combination on SO-50 at a hamfest earlier this month in southern Arizona. With Fox-1 in the pipeline, and SO-50 having a weak downlink, working full-duplex becomes more important than in the past with satellites like AO-27 and AO-51. 73!
