Durante la trasmissione in CW o RTTy l’apparato assorbe circa 18Amp. mentre in SSB con microfono originale HM-219\u00a0 assorbe al massimo 12Amp.<\/p>\n

During the trasmission in CW and RTTy the current abssorbed is around 18A, using SSB it not exced 12A, (Power Supply at 13.8V).Original HM-219 micro used<\/span><\/p>\n

Dopo una sollecitazione ricevuta da parte dell’Amico Martino IW7DNY il quale dopo aver visto la modifica sul mio sito personale che riguarda l’audio del l’IC7610, mi pone il problema della mancata erogazione dei 100W in SSB e mi ricorda la modifica fatta da Greg SP3RNZ e consulenza di Marios SV1CL sull’IC7300 che presenta lo stesso problema.<\/p>\n

After a solicitation received from an OM Martino IW7DNY who after seeing the change on my personal site concerning the audio of the IC7610, he asked me a solution regarding\u00a0 no full power delivered using SSB and reminds me\u00a0 the change made by Greg SP3RNZ and Marios SV1CL advice on the IC7300 which presents the same problem.<\/span><\/p>\n

in the picture as shown below the capacitor marked in red to be eliminated and the addition of the capacitor to the tantalum<\/span><\/p>\n

La Modifica \u00e8 semplice, consiste nel togliere C2037 ed aggiungere nel circuito un condensatore al Tantalio da 3,3uF 16V.\u00a0 Suggerisco di eseguire la modifica\u00a0 solo ad esperti in componentistica smd con attrezzatura da Laboratorio adeguata onde evitare di danneggiare l’RTX in modo irreparabile.<\/p>\n

The modification is simple, it consists in removing C2037 and adding a 3.3uF\u00a0 16V, Tantalum capacitor to the circuit.\u00a0 I suggest to perform the modification only to experts in smd components with adequate laboratory equipment to avoid damaging the RTX irreparably.<\/span><\/p>\n

Eseguita la modifica ho alimentato l’RTX con 13.8V e eseguito prove in SSB in diverse bande 160, 80, 60,40, 20mt l’erogazione della potenza \u00e8 100W e l’ALC non supera l’80% i corrispondenti mi dicono che la modulazione \u00e8 favolosa! Ho utilizzato il micro originale.<\/p>\n

Performed the modification I powered the RTX with 13.8V and performed tests in SSB in different bands 160, 80, 60.40, 20mt the power delivery is 100W and the ALC does not exceed 80% the correspondents tell me that the modulation is Amazing! I used the original micro.<\/span><\/p>\n

Disclaimer: Premesso che l’IC-7610 \u00e8 di per s\u00e8 una ottima Radio con la modifica\u00a0 suggerita vi consentir\u00e0 di arrivare meglio in SSB, tuttavia chi la esegue lo f\u00e0 solo a proprio rischio e pericolo, non mi ritengo in nessun modo responsabile di eventuali danni.<\/p>\n

Disclaimer: Although the IC-7610 is in itself an excellent Radio with the suggested modification will allow you to get better in SSB, however those who run it do it only at their own risk, I do not consider myself in any way responsible for any damage.<\/span><\/p>\n

Dopo una grande richiesta di aiuto, ho deciso di aggiungere altre foto (clicca per ingrandire) e spiegazioni riguardo a questa modifica.<\/strong><\/span><\/h4>\n
